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. Optional BDV1and / or BDV2 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. Maintenance For detailed Installation and Maintenance Instructions see IM-P128-06, which is supplied with the product. Disposal This product is recyclable.

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.
