Energy cut-off in the pump system and start and stop of the pump will cause pressure fluctuations caused by changes in water flow rate. When the energy is cut off, the valve opens quickly and discharges the negative pressure wave flowing back. When the negative pressure wave returns to normal, the valve closes slowly.

Technical specifications
Working with line pressure without additional energy consumption
easy to repair
Preventing pipelines from excessive pressure
Rapid detection of high and low pressure
Replacement balance tank use

Adjust
Provide electromagnetic coil energy through the board for the main valve. On the main valve, the miniature ball valves at the exit of the two miniature ball valves are closed. When the pilot valve adjustment bolt is turned clockwise, the adjustment pressure is lowered. When the required pressure value is reached, first tighten the lock nut under the adjusting bolt and then open the micro ball valve at the outlet.
