Type IVE mechanical isolation valve

The Type IVE mechanical isolation valve prevents hot particles, glowing embers and flames from passing through interconnected piping and potentially starting a fire that spreads from one vessel to the next. The valve remains open until receiving a signal from either a pressure transmitter and/or optical sensor that detects hot particles, embers and flames. Once signaled, the valve closes within milliseconds. Actuation occurs by means of a tank of compressed air located at the valve, which ensures the fastest responsepossible. The valve features a wear indicator in the bladder, which indicates exposure to abnormal wear by dislpaying a message on the controller.
