Surge relief valves

  - Quick response
The high-capacity proportional hydraulic design allows fast response to surge pressure. This results in prompt return to stable pressure conditions.

- Low-maintenance
Due to the absence of any external gas supply such as gas bottle, maintenance is reduced to the bare minimum, making the valve ideal for remote or inaccessible locations.

- High-performance
Surge valve designs are based on simplicity. All components are field-proven to provide maximum protection reliability. They operate solely on fluid static pressure.

- Stable operation
The design of the hydraulic incorporates snap-acting opening when the set pressure is reached and automatic switching to control in the event of continuing high-pressure conditions.
Surge relief valve Introduction
  Surge Relief Valves are consists of a main valve assembly and Hydraulic Actuator, Accessory, completely assembled and tested as a unit and ready for field installation.
The valves are open when system pressure exceeds its pressure setting and throttle as necessary to limit system pressure to a pre-set maximum pressure. When pressure subsides below the pre-set maximum the
valves are close tight.
