Stucture and purpose
Used on the pump outlet of a water supply system to prevent medium's back -flow,water hammer and water shock.combining three functions as anelectric valve ,check valve and W ater hammer remover, capable of effectively raisingsafety and reliability of the water supply system,integr ating thetechnical principle of slow-open, speed valve, slow- close removing water hammer and preventing both pump- starting and pump- stopping waterhammers fr om being formed.the gate can automatically carry out open-close upon the operation rules of the water pump just by operating the pumpto open or close electrically.this valve features a big flow and a small pressure loss,r eliable sealing performance, easy installation,debugging andmaintenance and a long duration.
