1. Steel hydraulic actuator butterfly valve mainly composed of valve, hydraulic station, quick closing actuator, PLC intelligent electric control box and special stroke feedback device;
2. Precision-machined rack and pinion hydraulic actuator, compact structure, stable operation, safe and reliable;
3. PLC intelligent electric control system, with high degree of automation, can control the system remotely and locally;
4. Using international famous brand automation components, the product performance is superior and the quality is reliable;
5. The power source for the normal opening and closing of the valve is generally provided by the supporting hydraulic pump station, and can also be derived from the main turbine hydraulic station;
6. The system power supply is 380V, and the control power supply is AC220V, DC220V, DC110V and other power levels;
7. The valve adopts three-eccentric multi-layer metal hard-sealed butterfly valve, high temperature resistance, flexible opening and closing, easy, and reliable sealing.
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.
The slow close hydraulic control check butterfly valve is mainly installed at the inlet of hydropower station and turbine, and is used as the inlet valve of water turbine or the water pump outlet of various pump stations such as water conservancy, power, water supply and drainage, etc. The heavy hammer type hydraulic controlled slow closing check butterfly valve mainly consists of butterfly valve, transmission system, hydraulic station, heavy hammer energy storage mechanism, locking device, electrical control system and other six parts.
