PC4_

Pipeline Connectors

Description

The PC4_ range of pipeline connectors have been designed for

use with swivel connector steam traps. The PC4_ is a pipeline

connector with two integral stop valves which isolate upstream

and downstream of the steam trap. The stop valves are piston

type. The PC4_ is available with optional connections (BDV1

and/or BDV2) for the draining of upstream pipework and trap

venting upstream and trap testing downstream of the steam trap

- See 'Optional extras'.

Optional extras (see TI-P600-01 for further details)

BDV1 blowdown valve is available for the draining of upstream

pipework and trap testing downstream of the steam trap during

operation. Care should be taken when using the BDV1 blowdown

valve as the discharge may be hot.

BDV2 depressurisation valve is available to provide side

connection discharge, generally to be used as a vent for top pipe

mounting or for line depressurisation, to ensure discharge is piped

to grade/atmosphere.

These products fully comply with the requirements of the

European Pressure Equipment Directive 97 / 23 / EC.

Certification

These products are available with certification to EN 10204 3.1.

Note: All certification/inspection requirements must be stated

at the time of order placement. For other certification contact

Spirax Sarco.

DN15 and DN20 condensate inlet/outlet connections are

available in screwed BSP or NPT and socket weld ends to

ASME B16.11 class 3000. Drainage and venting connections are

available in DN15 screwed BSP or NPT and socket weld

connections for use with BDV1 or BDV2 valves.

Flanged versions are also available upon request. Please contact

Spirax Sarco for further details.
