PKP ZJHP(M) pneumatic single-seat (sleeve) control valve

PKP ZJHP(M) pneumatic single-seat (sleeve) control valve consists of a pneumatic multi-spring diaphragm actuator and a hydraulic resistance straightway single-seat valve (sleeve valve); the upper valve cover of the singe-seat valve is provided with a valve stem guiding structure and the valve plug is a plunge structure; compared with a common single-seat valve, it has the characteristics of small size, light weight and big flow etc, which is suitable for occasions with large flow and strict requirements on leakage volume. Compared with a common sleeve valve, ZJHP(M) type mini-type sleeve valve has the advantages of smaller size (smaller by 1/3), lighter weight (lighter by 1/3) and bigger flow (bigger by 1/3), Which can be broadly applied into industrial process automatic control system requiting low noise and large pressure difference.
