PC4001, PC4000 and PC40

Pipeline Connectors

Description

The PC4001, PC4000 and PC40 range of pipeline connectors are a complete ‘Trap valve station solution’ developed for use with two bolt universal swivel connector steam traps.
As the unit has been designed with two integral piston stop valves, it is possible to isolate both upstream and downstream of the universal trap connection.

PC4001 and PC4000 models only
Through the use of the fitted depressurisation valves it is possible to depressurise, test and drain the pipeline.
The trap depressurisation port also incorporates a maintainable 40 mesh stainless steel strainer screen to provide trap protection from system dirt and debris, which can be cleared through the use of the line pressure.
