Basic Information of Anti Water Hammer Valve

This anti hammer water control valveis used to reduce the pressure fluctuation caused by the sharp change in the flow rate when the pump is closed or stopped due to power failure, thus protecting the water pump system.

Features of Anti Water Hammer Valve

1. anti water hammer check valvecan sense low-pressure waves and high-pressure waves.2. Sensitive induction, quick control3. Fast Opening to Maintain Line Pressure4. Full port, small fluid resistance

Principle of Anti Water Hammer Valve

Generally, the sudden stop of the pump will produce huge pressure fluctuations, the pressure in the sampling tube will also fluctuate at this time. The low-pressure pilot valve senses this initial pressure wave to open the drain so that the main valve opens to prevent high-pressure fluctuations from returning from the system. The opened main valve drains high-pressure waves into the atmosphere. The high-pressure pilot valve induces high-pressure waves which also open and keeps the main valve open. When the system pressure is lower than the preset pressure of the pilot valve, the high-pressure pilot valve is closed, the pressure of the main valve control room is increased, and the main valve is closed to maintain the system pressure in the pilot valve preset pressure.

Installation and Commissioning of Anti Water Hammer Valve

Determine the high and low-pressure settings, and adjust the pipeline pressure at low-pressure settings. At this point, the low-pressure pilot valve is set at the critical state of opening and closing and locking the nut. Adjust the pipeline pressure to the high pressure setting value, set the high-pressure pilot valve to the critical state of opening and closing to lock the nut. For specific use, please consult ZECO Valve Group.
