Product Description

Features and advantages
Equipped with balancing hammer device. The valve flap has little resistance to water flow when it is turned on, and the opening force is only one-fifth of the original turning type, which is an energy-saving product.
The back stroke of the valve disc is equipped with a damping device, and the damping time is adjustable to prevent the generation of destructive water hammer.
Novel rubber coated valve disc design, reliable sealing, anti-corrosion, vibration reduction and wear resistance, long service life; Smooth operation, low noise.
