FCA Flow Check Adaptor

Gauge ValvesAnderson Greenwood

A rotatable connecting adaptor used with static pressure measuring instruments which, in the event of the instrument rupturing, closes automatically as a result of the process medium flow

The FCA is designed for flow prevention, pressure snubbing, as a gauge siphon for steam service and for hazardous service including toxic, flammable and high pressure duties, providing extra protection for personnel and the environment.

  • Seals off the flow when activated by escaping gas or liquid.
  • Automatically resets when flow conditions cease or the instrument is replaced.
  • Integral restricted orifice acts as a pulsation damper reducing damage to sensitive instruments.
  • Rotatable adapter option allows 360° positioning of gauges and instruments.
  • Integral siphon for steam service provides a protective condensate barrier to prevent live steam from damaging instruments.
  • Robust and compact design allows rigid installation of gauges and instruments.
