Check Valves with Damper

Hanno Valve Check Valves with Damper are suitable for all kinds of working conditions, especially in the high head pumping station, which can effectively reduce the water hammer pressure and protect the system safety.

Check Valves with Damper are specialized valves designed to permit fluid flow in a single direction while effectively preventing reverse flow. These valves are equipped with a damping mechanism that slows down the closing speed, minimizing water hammer and ensuring smooth operation. The dampened closure helps reduce system pressure spikes and prolongs the valve’s lifespan, making it an ideal choice for systems requiring controlled flow and enhanced protection against shock.

Benefits of Check Valves with Damper

· Reduced Water Hammer: By controlling the closing speed, these valves help prevent sudden pressure surges.

· Increased System Protection: They protect sensitive downstream equipment from backflow and pressure fluctuations.

· Extended Valve Life: The gradual closing motion reduces wear on the disc and seat, prolonging valve longevity.

· Enhanced Flow Control: Ideal for systems where steady, one-way flow is crucial.

Applications

Check Valves with Damper are versatile components used in:

· Water Treatment and Distribution: Smooth and steady flow management for large water systems.

· Oil and Gas Pipelines: Preventing backflow and ensuring safe operation in pipeline systems.

· Power Plants: Controlling steam and other high-pressure media.

· Industrial and Chemical Processing: Providing controlled flow for abrasive or corrosive materials.

· HVAC Systems: Enhancing efficiency and stability in large-scale heating and cooling systems.

Installation Guidelines

· Ensure the valve is installed in the correct flow direction.

· Avoid installing in vertical piping if not specified for vertical use.

· Select appropriate materials and pressure ratings based on system requirements.
