CONVAL: Fire-Safe Valve / Vent Drain Combination
Conval announces the availability of the Clampseal Fire-Safe Valve factory-equipped with an SaVD Safe Vent Drain.This combination is ideal for refining and chemical plants where fire safety is a major concern, and is available in Y, A and T pattern configurations in 1/2" through 4" sizes; with up to ASME/ANSI 2500 pressure ratings; and with NPT, butt weld and socket weld ends.
The Clampseal Fire-Safe Valve contains a simple mechanism that compensates for thermal expansion. As a result of this and other design features, the valve meets API fire-safe standards by extremely high margins. In brief, the testing procedure calls for the test valve to be placed in line and pressurized to 75% of rated pressure, then subjected to a 1,400 - 1,800F fire for 30 minutes. The valve is then quenched with water to cool it to ambient temperature, cycled to prove operability, and then subjected to further pressure testing. The valve is required to maintain strict leakage allowances during and after the burn.
Manufactured to ISO 9001-2000, the ultra-safe SaVD Safe Vent Drain replaces bull plug and screwed caps, and requires just one weld to connect to the pipe. Safe depressurization is achieved in just one drip of fluid, significantly enhancing safety and environmental protection. The SaVD features secondary containment, easy cleaning and pressure purge, no-spill gravity drainage, and meets OSHA regulations.
