Features and advantages of HH44X micro-resistance slow-closing check valve
1. Equipped with counterweight device. When the valve flap is rotating, the resistance to the water flow is small, and the valve opening force is only
One-fifth of the original swing type is an energy-saving product.
2. There is a damping device on the back stroke of the valve flap, and the damping time can be adjusted to prevent the occurrence of destructive water hammer.
3. Novel rubber-coated valve disc design, reliable sealing, anti-corrosion, damping and wear-resisting, long service life; stable operation, low noise
