mud valve is also known as cover valve, commonly used in urban waterworks, sewage treatment plant sedimentation tank discharge sludge. sludge valve suitable medium for the primary sewage, medium temperature should generally be less than 50 ℃, its working depth is less than 10 meters. sludge valves are also used in water treatment plants as sludge and waste water in discharge basins. sludge valve angle structure, the internal nylon reinforced rubber diaphragm for long-term use of mud valve.
jm744x hydraulic, jm644x pneumatic angle fast open mud valve is a type of hydraulic or pneumatic source for the executive body angle truncated type valve. usually installed in rows at the bottom of the sedimentation tank on the outer wall to remove sediment sediment sediment and dirt. the valve is made of nylon reinforced rubber diaphragm divides the valve into two chambers, connected hydraulic or pneumatic source, controlled by electric or manual two-position four-way reversing valve to achieve rapid sludge discharge. the valve will replace the piston diaphragm, no friction, more suitable for slurry and other granular media, greatly improving the service life of the valve.
