Conval: Clampseal Fire-Safe Globe Valves

Conval eNews 10.15.14Conval offers Clampseal® fire-safe globe valves for refining and chemical plants where fire safety is a major concern. The fire-safe valves are available in Y, angle and T-pattern configurations in ½” through 4” sizes, up to ASME 2500 pressure ratings, and with NPT, butt weld, or socket weld ends. Other end connections are available upon request.

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. The testing procedure calls for the test valve to be placed in-line and pressurized for 75% of rated pressure, then subjected to a 1,400 – 1,800° fire for 30 minutes. The valve is then quenched with water to cool it to ambient temperature, cycled to prove operability, then subjected to further testing. The valve is required to maintain strict leakage allowances during and after the burn.
