Dry pipe valve
The Loss Prevention Certification Board (LPCB part of BRE Global) sets the standards needed to ensure that fire and security products and services perform effectively. LPCB’s Loss Prevention Standards (LPS) are applied in fire and security sectors around the world.
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, suggests that a dry pipe valve is an: ‘Automatic sprinkler water-supply control valve designed so that air pressure in a system of piping will hold back water pressure until the air pressure in the system is lowered sufficiently to cause automatic operation of the valve and admission of the water in the system, or the valve is tripped by direct action by an accelerator.’
A dry pipe valve set is: 'An assembly complete with dry pipe valve, trim and water motor alarm. Optional items, such as accelerator, exhauster, flow meter, pressure switch and flow switch may also be included as part of the dry pipe valve set.'
