This valve will be preferably installed at the bottom of the tank or near the basin

MODEL MV-AP

性能特点：
*入口压力直接作用在压力控制室，在设定值
时，阀门对压力反映灵敏、精确；
*出口压力可以从PT1/8”接口的压力表上直
接读出；
*阀门的阀体与上盖为螺栓螺母锁紧结构，非
螺纹直接锁紧。此种结构密封性更好。
DP型泄压/背压/持压阀是隔膜驱动阀。阀门在
管线压力到达其设定值时，自动开启，系统正常工作时，阀门受压缩弹簧的压迫，处于常关状态，阀门的有效受压面积比阀座大很多，所以设定压力可以很精确，阀门对入口压力的反映很灵敏。

*The Air Release Valves can remove
all pockets of air quickly whichentrained in a water transmission.
*Stainless steel trim assures lowmaintenance.
* Stainless steel floats unconditionallyguaranteed.
* Easily maintained without special tools.
*Complete interchangeability of all parts.
