Product Details:

 

L&T Valves Limited is a wholly owned subsidiary of Larsen & Toubro.

Backed by a fifty-year track-record of excellence and world-leading

innovation, the company provides engineered flow-control solutions for

key sectors of the economy such as oil & gas, power, petrochemicals,

chemicals, fertilizers and pharmaceuticalsL&T Valves manufactures a comprehensive range of Ball Valves in sizes

up to 8" (DN 200) and in ASME classes from 150 to 2500. The valves are

offered in combination of size, pressure class, material of construction,

end-connection, etc., to suit myriad applications in process plants, utility

lines and HVAC.

L&T Ball Valves are available in single-piece, two-piece and three-piece

constructions. In these valves, line pressure forces the floating ball against

the downstream seat to effect bubble-tight sealing.

Blowout Proof Stem

The side-entry stem of L&T Ball Valves has a

shoulder that bears against a matching shoulder

in the body to make it blowout proof - the

higher the line pressure, the better the sealing to

atmosphere.

Mirror-finished Solid Stainless Steel Balls

To obtain bubble-tight sealing and lower

operating torques, mirror-finished SS balls are

used as a standard. The solid construction of the

balls guarantees higher structural strength.

Inserts in single-piece Ball

Valves are provided with

a hexagonal slot for easy

removal.

Seats with Pressure-relieving Slots

Seats with fine grain structure are used to ensure

better strength and longer life. Pressure-relieving

slots are a unique feature of L&T Ball Valves. The

slots relieve upstream pressure when the valve is

 

in closed position and prevent seat damage.

High Integrity Stem Sealing

Sealing to atmosphere is further enhanced by

stem thrust seals and stem packing rings. To

compensate for wear and thermal expansions,

 

Belleville springs are used

Fire-Safe Feature

L&T fire-safe Ball

Valves feature

secondary metal seats.

In the event of a fire,

after the soft-seat

totally sublimates, the

ball moves and abuts

the downstream metal

seat to form a

leak-tight seal.

Cavity Pressure Relief Mechanism

A slight increase in temperature of fluid

entrapped in ball cavity can cause a rapid

increase of pressure and damage the ball and

seats.

To prevent this, L&T Ball Valves are equipped

with automatic cavity relief mechanisms. When

the valve is in open position, a hole provided on

the ball connects the body cavity to the ball port

and thereby ensure that cavity pressure does

not build up. In the closed condition, when the

cavity pressure rises above a designated level,

the seat lip deflects to relieve pressure to the

upstream side.

Antistatic Feature

Static electricity builds up inside a valve when

the ball rubs against non-metallic seats. This

is a fire hazard, especially in flammable fluid

pipelines. L&T Ball Valves have inbuilt antistatic

mechanisms to provide electrical continuity.

Stems of full bore valves of size 65 mm and

above and regular bore valves of size 80 mm and

above are equipped with spring-loaded plungers.

In valves of smaller sizes, electrical continuity is

achieved by using Carbon-filled PTFE thrust seal

 

and graphite stem packings.

Pressure

The strength of the vulcanised liner as well as its strong bonding with the

body ensure that it doesnt get deformed and torn by the disc during valve

operations. Further, friction during operations is minimised owing to the

smooth liner surface. The strong seat and reduced friction greatly enhance

 

service life of the valve.

Tight Sealing, and Consistent Low Torque

Bubble-tight sealing is obtained by the tight interference fit between liner

and disc. The insitu moulded seat does not deform with age, and hence

the operating torque stays low and consistent during the entire life cycle of

the valve. High reliability and consistent torque make Aquaseal 16 the ideal

 

valve for actuated systems

The flat profiles on the top and bottom of Aquaseal Plus disc engage with

matching profiles on the body liner, and the large area of contact prevents

leakage to atmosphere. Integrally moulded O-Ring that compresses around

 

the blowout-proof shaft provide a secondary seal.

Actuator Mounting Platform

The integral ISO 5211 platform facilitates direct mounting of actuators and

 

gear units, thereby improving system reliability and efficiency

Enhanced Reliability

The rugged body is designed to withstand

pipeline stresses and vibrations. Further,

enhanced liner thickness assures reliable

performance over an extended service.

Reinforcements are provided on Aquaseal 16

 

disc also.

Lower Torque, Longer Life

The Aquaseal 16 disc is profiled for smoother

flow. Further the coating/ encapsulation of Nylon

and EPDM on the disc helps to reduce torque

and prevent disc damage.

In Aquaseal 16 a two-piece shaft is employed for closer control and

smooth operation. The shaft is Xylan-coated to reduce friction and improve

wear resistance. While the square shaft provides positive drive, the bottom

 

shaft acts as a pivot for operational ease.

carrierASME B16.34 L&T Gate, Y-Globe & Swing Check ValvesPressure Seal Bonnet designThe ASME B16.34 family of L&T Gate, Y-Globe and Swing Check Valves features a pressure seal bonnet design for high pressure services. These valves are extensively used in high pressure and high temperature steam, oil, gas, chemical and water applications in thermal power plants, fertiliser plants, petrochemical plants and refineries. The valves are available with butt-weld ends in pressure ratings of Classes 900, 1500 and 2500, and come in carbon steel and alloy steel construction.Gate valves also meet the requirements of API 600 Style A.Seat ringsBody seat rings are welded to the body to offer a leakproof design as they eliminate the leakage path betwen the seat ring and the body. This design is superior to screwed seats which can loosen up due to temperature fluctuations, corrosion or vibration and result in leakage.TrimBoth the disc and the seat ring faces are hard-faced with Stellite #6 or equivalent.Back-seatThe back-seat is in-situ hard-faced with Stellite #6 or equivalent.Stem and Gland PackingThe valves feature a stem, made of 13% Cr. Steel - ACmE threaded, precision-machined and ground to a high finish to ensure a smooth operation. The high-purity graphite gland packings, used for stem sealing, provide capability to withstand high temperatures and pressures, and also to resist many chemicals. The smooth-finish stuffing box ensures longer life for the packings.AccessoriesL&T Valves can be supplied with accessories such as bypass arrangement, drain plugs, live-loading and mountings like extension spindles, floor stands and chain wheel. The valves can also be supplied with gear units and electrical actuators.Yoke Sleeve and Thrust BearingsThe yoke sleeve is made of nodular niresist Iron, supported by a set of bearings to reduce friction and the consequent torque required to operate the valves. nodular niresist Iron also withstands high temperatures. Weather seals, provided in the yoke sleeve, protect the bearing area against ingress of dirt and water.Gate ValVesParallel Slide disc MechanismThis mechanism consists of two independent discs held by a disc carrier. An alloy steel spring between the discs provides the initial loading to keep the discs pressed against the body seats. The disc faces are parallel to each other and seal on parallel seat rings in the body. Sealing takes place by utilizing the line pressure to provide tight seal on the downstream seat. As the two discs are independent and parallel, opening / closing torques are significantly lower than comparable wedge disc designs, thereby minimizing the possibility of jamming at high temperatures or pressures.When the valve is operated, the discs are allowed to slide and rotate over the body seats. This helps wipe out foreign particles from the seat faces.Pressure Seal arrangement for body-bonnet jointThis pressure seal body-bonnet joint utilizes the line pressure to create a tight body-bonnet seal. Sealing is achieved by compressing a high-purity graphite gasket between the bonnet and the body retainer ring. Preloaded fasteners provide an initial tight seal at low line pressures. At higher pressures, the line pressure pushes up the bonnet against the gasket, compressing it further and providing a much tighter seal.

y-GloBe ValVesBy virtue of their Y-type configuration, L&T Y-Globe Valves have a relatively straight flow and a lower pressure drop compared to conventional globe valves. The valves are suitable for tight shutoff and throttling in high pressure and high temperature lines.Some of the unique features of L&T Y-Globe Valves are : Pressure Seal Bonnet Low operating torque due to use of thrust bearings non-rotating stem Integrally-stellited body seats Fully-guided disc with Stellite seating and guiding surface Impactor handwheel in sizes of 6 (150mm) and aboveordering

Quality Valves manufactures a comprehensive range of Ball Valves in sizes

up to 8 (DN 200) and in ASME classes from 150 to 2500. The valves are

offered in combination of size, pressure class, material of construction,

end-connection, etc., to suit myriad applications in process plants, utility

lines and HVAC.

Quality  Ball Valves are available in single-piece, two-piece and three-piece

constructions. In these valves, line pressure forces the floating ball against

 

the downstream seat to effect bubble-tight sealing

Blowout Proof Stem

The side-entry stem of Quality Ball Valves has a

shoulder that bears against a matching shoulder

in the body to make it blowout proof - the

higher the line pressure, the better the sealing to

atmosphere.

Mirror-finished Solid Stainless Steel Balls

To obtain bubble-tight sealing and lower

operating torques, mirror-finished SS balls are

used as a standard. The solid construction of the

balls guarantees higher structural strength.

Inserts in single-piece Ball

Valves are provided with

a hexagonal slot for easy

removal.

Seats with Pressure-relieving Slots

Seats with fine grain structure are used to ensure

better strength and longer life. Pressure-relieving

slots are a unique feature of Quality Ball Valves. The

slots relieve upstream pressure when the valve is

in closed position and prevent seat damage.

Actuator Mounting Flange

Quality single-piece and two-piece Ball Valves are

provided with an integral actuator mounting

flange conforming to ISO 5211.

Please note that full bore valves in sizes DN 15 to DN 25

would be supplied with mounting arrangement as per L&Ts

manufacturing standard.

High Integrity Stem Sealing

Sealing to atmosphere is further enhanced by

stem thrust seals and stem packing rings. To

compensate for wear and thermal expansions,

 

Belleville springs are used.

Fire-Safe Feature

Quality fire-safe Ball

Valves feature

secondary metal seats.

In the event of a fire,

after the soft-seat

totally sublimates, the

ball moves and abuts

the downstream metal

seat to form a

leak-tight seal.

Cavity Pressure Relief Mechanism

A slight increase in temperature of fluid

entrapped in ball cavity can cause a rapid

increase of pressure and damage the ball and

seats.

To prevent this, Quality Ball Valves are equipped

with automatic cavity relief mechanisms. When

the valve is in open position, a hole provided on

the ball connects the body cavity to the ball port

and thereby ensure that cavity pressure does

not build up. In the closed condition, when the

cavity pressure rises above a designated level,

the seat lip deflects to relieve pressure to the

upstream side.
