PC3_

Pipeline Connectors

Description

The PC3_ range of pipeline connectors have been designed for

use with swivel connector steam traps. The PC3_ is a pipeline

connector with one integral stop valve which isolates upstream of

the steam trap. The stop valve is a piston type. The PC3_ is

available with optional connections (BDV1 and / or BDV2) for the

draining of upstream pipework and trap venting upstream 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 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.

Standards

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.

Sizes and pipe connections

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.
