RC-1 type delay fluctuations in water pressure in the water supply system, an instant rise in water pressure valve plate open, water flows out of stainless steel valves from the alarm port, due to the delay buffer cavity, will not alarm immediately. When the momentary fluctuations in pressure drop, the valve plate to close the valve Legend delay chamber through the throttle body assembly water outlet orifice emissions. Anyuan Hubei Chong Mechanical and Electrical Equipment Co., Ltd. The company provides FM spray product certification, FM certification sprinklers, FM certification deluge valve FM certification / UL registered sprinkler system products Tyco central spray Po (TycoFire & amp; Building Products) series spray shower systems Valves, including various types of sprinkler head, wet alarm valves, deluge valves, flow indicator PS10A / PS40A Series pressure switch PS10A series is a pressure type flow detection switch, into PS10-1A (including an SPDT contact) , PS10-2A (including two SPDT contacts), in the wet, dry and pre-action system, connected to the valve on the water pipe alarm interface pneumatic valve, the valve is opened based on the flow monitor. Only one sprinkler head movement can flow pressure switch operation. In the pre-action system connected to the outlet valve at the pipeline pressure monitoring system, when the pressure decreases, issue a low pressure alarm signal. Operating pressure can be between 4-20psi (0.28-1.38bar) regulation. Switch must be installed vertically.
