JM744X, JM644X diaphragm type hydraulic, pneumatic quick opening mud valve, is a hydraulic source or pneumatic source as the actuator of the Angle type cut-off valve.Usually mounted in rows on the outer wall of the bottom of the sedimentation tank to remove the sediment sand and dirt from the bottom of the tank.The valve is divided into two Chambers by nylon reinforced rubber diaphragm, connected with hydraulic or pneumatic source, using electric or manual two four-way reversing valve control, to achieve rapid mud discharge.The valve will replace the diaphragm piston, no motion friction, more suitable for mud and other granular media, greatly improve the service life of the valve.
1. The valve body adopts full channel and streamline design, with small fluid resistance and large flow rate.
2. The joint of body, cover and piston rod is double sealed by sealing gasket and sealing ring without leakage.
3. Double guide of valve body, piston cylinder and piston ensures stable and reliable movement.
4. All stainless steel piston cylinder, integral casting piston and NBR sealing ring. Perfect combination greatly prolongs service life.
5. The detachable valve seat with advanced technology has ingenious structure, novel conception and convenient maintenance and replacement.
6. For the piston cylinder with guide hole, properly increase the resistance to make the piston movement more stable.
