PPA自動排氣閥用于自動噴水滅火系統、給排水系統及輸水系統等流體為水的系統中，排出水中的空氣
PPA 自動排氣閥用于自動噴水滅火系統、給排水系統及輸水系統等流體為水的系統中，排出水中的空氣。
自動排氣閥有普通，電控兩種形式。
自動排氣閥主要用于濕式系統及給排水系統中．可以把管網加壓過程中，水流動時由于改變壓力，流速而從水中析出的空氣排盡．從而減少管網中水錘現象。提高系統工作效率。
PPAD 電控自動排氣閥通過電磁閥來控制，電磁閥打開時排氣，關閉時，系統內可以充氣，主要用于干式系統和預作用系統，電磁閥由總控室控制，有火情時．通過驅動模塊打開電磁閥，加速系統排氣，縮短了管網充水時間，提高滅火效率。
PPA automatic exhaust valve use for automatic sprinkler systems, water supply and drainage systems and water conveyance systems, and such water fluid systems, exhaust air from water.
Auto exhaust valve have two forms of common and electronic control.
Automatic exhaust valve is mainly used for wet systems and drainage systems. It could exhaust air which separates out from water during the forcing procedure on tube network, caused by the pressure and speed changes by water flow. Thereby reduce the water hammer appearance in the pipe network. Improve the system efficiency.
PPAD electronically controlled automatic exhaust valve is controlled by a solenoid valve, when the solenoid valve opens, the air exhaust, when closed, can be inflated within the system, mainly used for dry systems and pre-action system, the solenoid valve control by the master control room, when a fire, open the solenoid valve through drive module, speed up the exhaust and shorten the time of filling water
of pipe network, improve firefighting efficiency.
