Explosion Isolation Pinch Valve

Overview

An active mechanical isolation protection device that collaborates with a control panel and explosion detector. It employs a  rugged  elastomer sleeve and compressed air to rapidly pinch the device into full closure within milliseconds of detection, protecting downstream equipment from flames and pressure.

Features

  • Bi-directionally isolates explosions in the process flow
  • Super fast Interception Valve
  • Designed to prevent explosion propagation
  • Quick reset after activation, avoid downtime
  • No refurbishment needed
