Safety Pressure Relief Surge Anticipating Valve

Features

1) Maintain safe and stable pressure, once overpressure or pressure dropped below the set value, main valve can be fully opened to drain and release pressure in time.

2) Closing speed is adjustable, to eliminate the valve closing pressure fluctuation.

3) Diaphragm transmission mechanism minimizes operational hysteresis. Response time is short, high sensitivity.

4) It can be installed in any position, can be repaired and checked without changing pressure set value or removing from the pipeline.

5) Streamlined wide valve body. Y-shaped full opening flow channel design, to ensure that the valve has the largest discharge capacity and good anti-cavitation ability.

6) Enlarged conduit and installed filter to reduce the risk of blocking.

7) Quick response.  High sensitive pressure components can respond to pressure changes in time. Reliable adjustment makes the valve pressure relief hammer elimination action in accordance with water surge propagation speed.

8) V-shaped plug and unique pilot valve design, the valve adjustment is more convenient, and operation is more stable.

9) The protection pressure and the discharge time can be set freely according to the site conditions.

10) The valve has a self-inspection and valve working status indicate function to ensure that the valve is always in good working condition.

11) The electronic control part has its own power supply, even if the power fails, it will not affect the valve working.
