Safety information

Pressure

Before attempting any maintenance, consider what is or may have

been in the pipeline. Ensure that any pressure is isolated and

safely vented to atmospheric pressure before attempting to

maintain the steam trap. This is easily achieved by fitting Spirax

Sarco depressurisation valves types BDV1 and BDV2 (see

separate literature for details). Do not assume that the system is

depressurised even when a pressure guage indicates zero.

Temperature

Allow time for temperature to normalise after isolation to avoid the

danger of burns and consider whether protective clothing

(including safety glasses) is required.

Isolation

Consider whether closing isolating valves will put any other part

of the system or personnel at risk. Dangers might include; isolation

of vents, protective devices or alarms. Ensure isolation valves are

turned off in a gradual way to avoid system shocks.

Installation

General

There are two criteria which must be satisfied to ensure that the

swivel connector trap will operate correctly and ensure effective

condensate removal:

1. The PC4_ shall be installed with flow in the direction of the arrow.

Flow can be horizontal (left to right or right to left), vertical or

inclined.

2. The connection face for the swivel connector steam trap must

be in the vertical plane.

Ensure that there is sufficient access to the handwheel to allow

proper operation.

After installation it is recommended that the pipeline connector is

insulated to minimise radiated heat losses and to protect

personnel from burns risk: Please note that some steam trap

types should not be insulated.

If the optional BDV1 and/or BDV2 is being fitted to your application

for line drain, trap vent or trap testing, consideration must be given to

the position of the discharge - See TI-P600-01 for further information.

The discharge must be directed or piped to a safe place where it will

not injure personnel nor damage plant.

The BDV1 provides straight through discharge, generally used as a

line drain or trap test valve where discharge is directed to grade.

The BDV2 provides a side connection discharge, generally used as

a trap vent or to ensure discharge is piped to grade.

For detailed Installation and Maintenance Instructions see

IM-P128-06, which is supplied with the product.

This product is recyclable. No ecological hazard is anticipated with

How to order

Example: 1 off Spirax Sarco PC40 pipeline connector having a

forged austenitic stainless steel body with two integral piston valves

and DN15 socket weld connections to ASME B 16.11 Class 3000.

Note: Where BDV1 or BDV2 valves are to be fitted they must be

ordered separately - See TI-P600-01.

The spare parts available are shown in heavy outline. Parts drawn

in broken line are not supplied as spares. For ease of replacement

an extractor tool is available for removing the sealing rings.
