| RICO Safety
The Rico family of Ventex explosion barrier valves provides protection against the propogation of an explosion from one process vessel or area to another. They are extremely effective where the dust concentration is low in the xplosive category 1 and 2 range. The standard valves require no external electrical detection or control and little maintenance. CONCEPT The Rico Ventex Valves use a suspended valve poppet. Under normal operation the air stream flows freely around the valve poppet. When an explosion occurs the valve poppet is thrown against the internal valve seat and locks into a closed position. Units are available in single and bi-directional versions. An additional version offers the benefit of assisted closing for applications with fast flame propagation. The ESI-R model can be fitted as a check valve. BENEFITS - No Detection or Controls Required - Low Cost Maintenance - Speedy Low Cost Reconditioning - Fast Action Assisted Version Options -Cost Effective Design DESCRIPTION The Rico Ventex Explosion isolation valves are used in applications where cost effective isolation, without sophisticated explosion detection and control systems are required. Their unique design allows them to be reconditioned, maintained and re-used at exceptional low cost of operation. The valves basic construction uses a valve poppet suspended in the flow area between one or two valve seats. An explosion force (Pressure Wave) moving ahead of the flame front hurls the poppet forward to the valve seat providing an airtight seal. The poppet once seated is locked in by a mechanical shut-off device which retains the seal until manually re-set. The three basic versions of the standard mechanical Ventex valve are available with a set pressure of 1.5 PSI and a maximum pressure of 150 PSI. The maximum operating teperature is 90 deg C for Neoprene Seal units and 150 Deg C and 260 Deg C for optional two Silicone Seals units. The valves are designed for a maximum normal air velocity of 66 ft/sec (20m/sec). Optional configurations are available on request. Vapour use is subject to Rico approval. |  |
