High-pressure Thermodynamic steam trap with socket weld ends as standard.
Trap to be inline maintainable with complete replacement of operating
internals. The trap is constructed with alloy steel, suitable for operation
from 116 psig to 3,190 psig. The trap comes standard with sinter stainless fine
Install in a horizontal pipeline with the nameplate on top. After 24 hours in
service, the cover nuts should be checked for tightness. Full-port isolating
valves should be installed upstream and downstream of the trap.
This product can be maintained without disturbing the piping connections.
