Multifunctional Check Valve

Features:

1.Multifunctional check valve: It integrates the functions of cut-off, check-back, and water hammer elimination.

2.Slowly open the pump: During the pump starting, the valve inlet pressure reach a predetermined value before the valve opens, which can reduce the pump starting current and protect the motor and electronic control system.

3.When stopping the pump, it first closes quickly and then slowly closes, effectively eliminating water hammer and ensuring system safety.

4.Good flow condition: The opening and closing parts are of inclined butterfly plate type, with smooth water flow and small pressure loss.

5.Reliable sealing and zero leakage: using soft sealing structure and metal hard sealing structure, the friction torque is small. The oblique eccentric structure sealing pair shortens the valve closing stroke, reduces the sliding distance, and reduces friction torque, achieving an instant separation. Therefore, it has the functions of sediment prevention and automatic pressure compensation.

6.Simple maintenance: There is no external power or components, and there are few fault points for maintenance.

7.Tilting disc check valve butterfly type: It adopts butterfly structure, which is small in size, light in weight and takes up little space. It reduces costs while increasing system reliability and stability and saving energy consumption.

8.When the nominal diameter is > DN300, the valve is equipped with a buffer piston damping protection device, which can protect the valve sealing surface and reduce the vibration and sound during closing the valve.
