QRS type electronic dry-valve fast opening external device reset QRS Electronic Accelerator dry type valve is fast opening valve means dry wet rain valve wholesale, can reduce when one or more action dry sprinkler valve opening time. Electronic Dry Accelerator uses a unique valve system air pressure monitoring device (UL and ULC announced, FM certification QRS type fire extinguishing system accessories) wet rain valve quality, 2 times per second continuous sampling system air pressure. When the air pressure decline rate than 0.007bar / sec of continuous falls, confirmed by three consecutive samples, QRS send a signal to the fire control box, fire control box emit electromagnetic valve open signal, QRS open valve solenoid valve wet rain, QRS system pipe network pressure through a pipe into the dry valve seat intermediate chamber, and the dry valve to accelerate open. QRS Electronic Accelerator has the following characteristics: * dry pipe valves in four seconds or less action - depending on different combinations of pressure pipe network, pipe network volume, nozzle flow coefficient K values. * Built-in low pressure and high pressure alarm monitoring devices. * When the backup battery with good wet rain valve to ensure reliable operation of mains failure Tyco Fire Suppression and Building Products TFS & amp; BP provide fire program and auxiliary building solutions for commercial, industrial, institutional, government agencies and housing Construction solution. Its focus is research and development in chemical and water-based fire-fighting technology, providing innovative technology solutions and global certification. Key products include sprinkler systems and valves, piping products and accessories, manual fire fighting equipment, fire detection / suppression systems, fire extinguishing agent. AV-1 type wet alarm check valve DN65 ~ DN200 ductile iron manhole covers and hand seat for the bronze, DN65 valve, stainless steel valve, other valves of ductile iron valve, all valves are made of EPDM for clapper facing.
