Excess flow valves (threaded)

  • Precision machined
  • Low pressure drop = minimised cavitation in pump suction lines
  • Cotter pin preventing loss of spring retainer
  • Consistent closing flow by stainless steel spring
  • Long service life
  • Separate models for installation in half or full coupling

Excess flow valves are safety devices that check flow lines and protect against surges in which case they shut-off the flow. They are installed in flow lines and are designed specifically for pressure gauges, pipelines and tank nozzles.

Did you know?

Every excess flow valve has a bypass feature not exceeding a #60 drill, which allows a small amount of product to pass downstream of the seat disc

The valve will automatically reset itself as the pressure will pass through the bypass area to reach the downstream side, which is then increased to match the pressure on the upstream side

NOTE: A threaded type, designed to be installed in a threaded flange, is available from 2″ to 8″
