Sherwood GRPV valves are designed to retain approximately 30 to 50 psig pressure, maintaining the integrity of the cylinder contents against contaminants,, even if the valve is left open. The unique combination of innovative design and quality construction offers protection of cylinder contents without the expense of a time consuming purge and clean cycle.
