Quick Opening Mud Valve
Product overview
JM744X, JM644X Diaphragm hydraulic and pneumatic quick opening mud valve is an angle type block valve with hydraulic or pneumatic source as the actuator. It is usually installed in rows on the outer wall of the bottom of the sedimentation tank to remove the silt and dirt deposited at the bottom of the tank. The valve is divided into two chambers by nylon reinforced rubber diaphragm, connected with hydraulic or pneumatic source, and controlled by electric or manual two position four-way reversing valve to realize fast sludge discharge. The valve uses diaphragm instead of piston, which has no moving friction. It is more suitable for particle media such as mud, and greatly improves the service life of the valve.
Product Features
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.
