slow close hydraulic control check butterfly valve
slow close hydraulic control check butterfly valve
The potential energy characteristics of heavy hammer type slow close hydraulic control check butterfly valve have higher safety coefficient than other hydraulic control valves, and it has double functions of gate valve and check valve. The valve opens with the weight lifting and maintains the fixed potential energy of the heavy hammer for a long time. When the motor unit of the oil pump fails or the power is cut off, the weight hammer slowly decreases with the gravity of the ground, and closes the valve.
