Ductile iron micro-resistance slow closing check valve HH44X-16Q

HH44XMicro-resistance slow-closing check valveIt consists of valve body, valve cover, valve flap, valve spindle andcontrol valveIt is installed at the outlet of water pump to prevent the medium from backflow and eliminate destructive water hammer, and can effectively reduce the water hammer pressure of the valve closure, which can guarantee the safe operation of the pipeline network. It is characterized by light valve flap, large opening, small fluid resistance, novel design of water hammer elimination mechanism, reliable sealing, long service life, smooth operation, no vibration, no noise and so on.

Product Features

• Micro-resistance slow-closing check valve has the characteristics of light valve flap, large opening, small power-saving loss, small fluid resistance, novel design of water hammer elimination mechanism, stable and reliable sealing performance, wear-resistant, long service life, smooth operation, no vibration, no noise and so on.

• Equipped with a balancing hammer device. The resistance to water flow is small when the valve flap is rotating, and the opening force is only one-fifth of the original rotating type, which is an energy-saving product.

• The latter part of the flap closing stroke is equipped with a damping device and the damping time is adjustable, which prevents the generation of destructive water hammer.

• Novel rubber-covered valve flap design, reliable sealing, corrosion prevention, vibration and wear resistance, long service life, smooth operation, low noise.
