The Explosion Isolation Pinch Valve (EIPV) is an economical, yet reliable form of explosion isolation — a method for preventing deflagration propagation through interconnecting pipes or conveyor lines. The EIPV consists of a cast valve body containing an elastomeric sleeve. Upon explosion detection, compressed air is released at high speed and within milliseconds, the sleeve is pinched to full closure, stopping explosion propagation beyond the valve. The valve has been proven to block explosion pressures of 3 bar. — Fike, Blue Springs, Mo.
