JM744X, JM644X diaphragm hydraulic, pneumatic quick open sludge valve, is a kind of hydraulic source or pneumatic source as the actuator of angular truncation valve, usually installed in rows on the outer wall of the bottom of the sedimentation tank to remove the sedimentation and dirt at the bottom of the pool. JM644X pneumatic angle type quick open mud discharge valve is divided into two chambers by nylon reinforced rubber diaphragm, connected to hydraulic or pneumatic source, and controlled by electric or manual two-position four-way directional valve to achieve fast sludge discharge. JM644X pneumatic angle type quick open mud valve The diaphragm replaces the piston without motion friction, which is more suitable for granular media such as slurry, which greatly improves the service life of the valve.
