Product Description

Structure and Usage:

The valve is mainly composed of main valve, one-way valve, needle valve, ball valve and pressure gauge. The slow-closing check valve has the check function of opening and closing speed control. After the valve is installed, it can effectively control the pump to automatically adjust to the best speed when it starts and stops. It is suitable for industrial and mining enterprises and high-rise buildings to directly supply and drain water pumps to reduce water hammer and water hammer to achieve the effect of safe shutdown.
