LPS 1041 – 1.3, Requirements and testing procedures for the LPCB approval and listing of dry pipe valve sets, published by BRE Global in 2014, defines a mechanical type dry pipe valve as a: ‘Type of dry pipe valve in which a mechanism acts to produce a force which is multiplied through a series of levers, links, or latches to maintain the water sealing assembly in the closed position. Operation of this type of valve is generally independent of water pressure.'
