What is the difference between PC4001, PC4000, and PC40 models?

The PC4001 includes two piston isolation valves, upstream and downstream depressurisation valves, and a bypass valve with line drainage. The PC4000 has isolation and depressurisation valves but no bypass. The PC40 is the basic model with no valve connections—it serves as the connector body only.

Are these pipeline connectors IBR certified for use in India?

Yes, the PC4001, PC4000, and PC40 pipeline connectors fully comply with Indian Boiler Regulations 1950. All IBR certification and inspection requirements must be specified at the time of order placement.

What steam traps are compatible with these pipeline connectors?

These connectors are designed for use with Spirax Sarco two-bolt universal swivel connector steam traps. The maximum operating limits of the complete assembly depend on the specific steam trap selected—refer to the trap's technical documentation for pressure/temperature limits.

Can these connectors be installed in vertical pipelines?

Yes, the PC4001, PC4000, and PC40 can be installed horizontally, vertically, or inclined. However, the connection face for the swivel connector steam trap must remain in the vertical plane unless the trap's installation instructions state otherwise.

What spare parts are available for maintenance?

Spirax Sarco supplies sealing ring sets, piston valve assemblies, piston valve sub-assemblies, depressurisation valves with gaskets, bypass valve assemblies, strainer screens (pack of 3), and an extractor tool for sealing ring removal.

Overview

The Spirax Sarco PC4001, PC4000, and PC40 pipeline connectors are engineered trap valve station solutions designed for use with two-bolt universal swivel connector steam traps. These units provide a complete, factory-assembled station that simplifies steam trap installation and maintenance in industrial steam systems.

Each pipeline connector features two integral piston stop valves, enabling full isolation both upstream and downstream of the trap connection. The PC4001 and PC4000 models include depressurisation valves that allow safe system depressurisation, testing, and drainage. The trap depressurisation port incorporates a maintainable 40-mesh stainless steel strainer screen to protect the trap from debris, which can be cleared using line pressure.

These pipeline connectors comply fully with Indian Boiler Regulations 1950 (IBR), making them suitable for regulated steam installations across Indian manufacturing facilities.
