Features And Benefits
This valve is through the valve plate linear movement to the valve seat to realize the opening and closing of the valve.This kind of valve is mainly assembled in the horizontal pipeline, the main function is to prevent the medium backflow when the water pipe needs to be repaired and thus the pump is shut down.
Excellent Sealing Performance
Ensure good sealing effect, effectively prevent leakage, applicable to a variety of media and working conditions.
Lifting Valve Plate
Equipped with lifting valve plate design to enhance the accuracy of flow control and flexible operation.
Wide Range Of Applications
Adapt to a variety of working conditions, can be widely used in different industrial fields.
Quick Closing
The valve plate supports quick closing function, which improves the operation efficiency and reduces the switching time.
Low Closing Shock
The design effectively reduces the impact force when closing, reduces the vibration of the system, and protects the equipment and pipelines.
