The HH44X stainless steel micro-resistance check valve is specifically designed for pump outlet applications, primarily used to prevent reverse flow of the medium and eliminate destructive water hammer, ensuring the safe operation of the pipeline network. The following are its core features:
Core Performance
Work Pressure: 1.0-2.5 MPa
Applicable Temperature: ≤80℃ (expandable up to 200℃)
Applicable Medium: Freshwater, Sewage, Sea Water, etc.
Nominal Pipe Size: DN40 - DN800
Structural Features
Valve Body Material: Stainless Steel
Valve Disc Design: Rubber-coated valve disc paired with stainless steel valve shaft, ensuring stable sealing and corrosion resistance.
Balancing hammer assembly: Valve opening resistance is only one-fifth of that of traditional swing check valves, offering significant energy-saving effects.
Damping Mechanism: Features adjustable closing time from 0-60 seconds, staged closure to reduce water hammer pressure.
Applicable Scenarios
Suited for industrial, agricultural, municipal water supply and drainage systems, as well as petrochemical fields, particularly effective in reducing fluid resistance at pump outlet and extending service life.
