Combined Butterfly-Check Valve

Basic information
This valve acts as a closed circuit valve and a check valve to protect the system by avoiding and reducing the backflow of the intermediate fluid in the piping system and causing excessive water hammer.
Features
1. Valve opens automatically when the pump starts and closes automatically before the pump is stopped;
2. In case of power failure at the pumping station, the valve closes like a hydraulic damped check valve;
3. Both opening and closing times are adjustable;
4. The hydraulic power pack is also equipped with a handpump for emergency opening of the valve.
Principle
This combined butterfly check valve is opened by means of a cylinder driven by the hydraulic power pack. The valve is only set to open at a constant speed, and the opening time can be adjusted by adjusting the knob of the valve opening in the hydraulic oil station. Before the 75 ° fast closing, time is 5 ~ 12 seconds (adjustable site); after the 15° slow closing, time is 20 ~ 40 seconds (adjustable site). The realization of closing the valve fast and slow is mainly regulated by controlling the amount of oil drainage through adjusting the two-way oil drainage regulating device. The regulating part is in the part protruding from the upper part of the oil cylinder. If the adjustment is needed, the part protruding from the upper part of the oil cylinder should be removed.
