Description
The BDV depressurisation valves are designed to be fitted into 3/8", 1/2" and DN15 connections for drain/blowdown/purge and vent/depressurisation of pipework or products.
The BDVi provides discharge straight through the valve, generally to be used as a drain, or for line depressurisation where discharge is directed to grade/atmosphere.
The BDV2 provides 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.
BDV1 /BDV2 fitted to pipeline connectors PC3_ / PC4_: When a depressurisation valve type BDV1/BDV2 is fitted to a pipeline connector type PC3_/PC4_ designed for use with swivel connector steam traps, the valve can be used for drain/vent/depressurisation of pipework and upstream/downstream trap testing. An internal drilling is provided in certain connector bodies specifically fortraptesting. Where it is acceptable to discharge to atmosphere a BDV1 may be used for line drain and trap test service.Where it is not acceptable to discharge to atmosphere the BDV2 should be used and the piped discharge taken to a suitable point.For upstream trap vent applications always use a BDV2.
