Fike introduces new Explosion Isolation Pinch Valve

Feb. 22, 2010 - PRLog -- In addition to Fike’s fast acting mechanical slide gate valve and the chemical barrier system, Fike now offers a pneumatically operated Explosion Isolation Pinch Valve.

The Fike Explosion Isolation Pinch Valve (EIPV) consists of a heavy duty cast valve body containing a rugged elastomer 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.

A deflagration propagating through a conveying line may cause pressure piling, rapid flame acceleration and transition to detonation if not disengaged in a timely manner.  The resulting explosion will not only damage the pipeline and accessories but also make adequate protection of downstream process equipment (e.g. Dust Collectors, Dryers and Silos) virtually impossible due to the effects of flame jet ignition and pressure piling in the receiving vessel or apparatus.

Used in conjunction with other Fike explosion protection system components, the EIPV is designed to provide a cost effective way to prevent deflagration propagation.

The EIPV System uses a heavy duty food grade elastomeric sleeve, high-speed solenoid valves, pneumatic accumulator, high and low pressure alarm switches and shut off/bleed/manual operation valves.

The main features of the Fike product include:

• Provides a mechanical obstruction to explosion flame and pressure
• Fast closure with minimized installation distance from vessel
• No pyrotechnical devices required to activate the valve
• No reaction forces upon closure
• Supervised accumulator pressure included
• Suitable for vertical or horizontal mounting
• Can be operated and reset by user
• Virtually maintenance free
• Uses standard plant air
• Sanitary design – elastomeric sleeve extends to the full face of the flange, eliminating potential for bacterial contamination
• Full-port design reduces pressure drop and avoids material accumulation
• Available in a variety of international flange standards and sleeve materials
• Food grade sleeve standard
• Proven concept, large-scale tested at Fike
• Third party tested and certified (CE, ATEX)
