Mud valve installed in the water company or other types of pool next to the pool in order to rule out any sediment pool. Valves of the main features of the dual-chamber diaphragm replacement piston drive mechanism, no moving wear, the product from the hydraulic cylinder and valve combination Jiao-type cut-off is made, hydraulic cylinder valve dynamic drive down to open or close valve Tong Dao, to achieve the fluid off. Hydraulic cylinder piston seal for the L-cups, the sealing performance and durability. Valve flap and valve seat for the soft seal, seal performance, no leakage. The use of electric two four-way valve or reversing valve manually two centralized control, easy to operate. The principle and performance: the valve from the valve, hydraulic cylinder, piston, valve stem, valve flap formed cylinder liquid instruments. Liquid as the driving force, piston, valve stem as a switch. Open just a minute to open the valve plate, the valve must be fitted with a manual valve or solenoid valve for side can be remote controlled mud valve switch, the valve sealing performance, the switch flexible, easy maintenance, long service life, life up to five years.
