Excess Flow Valves

Safety Excess Flow Valves for guaranteed shut-off in your system


Our range of automatic controlled bleed and manual reset excess flow valves are the perfect solution for preventing uncontrolled flows of gases and liquids. They can be considered for the following primary uses:


  • As a Safety Product for use with aggressive and toxic media systems to prevent potentially deadly leaks or pipework ruptures. The excess flow valves can be factory pre-set according to individual process parameters to detect and shut-off lines on either increasing or decreasing flow conditions.

  • To provide Commercial Savings as they can be used to stop precious and expensive media (such as Helium) from escaping through relief valves to atmosphere or protected waste areas. Units can be specified to provide a positive shut-off to prevent any loss of media.
