GSRPV Series Residual Pressure Cylinder Valves

Sherwood GSRPV global industrial residual pressure valve are used in cylinders containing inerts, oxidizers and flammables designed to prevent backflow contamination in the cylinder. Valves are available with various inlets and outlet specifications, with or without pressure relief devices, and standard brass or chrome plated exterior.

Key Features & Benefits

Prevents backflow of impurities and foreign substances
Durable forged brass body, precisely machined internal components and design elements meet the most stringent international valve performance standards
Innovative design and quality construction offer protection of cylinder contents without the expense of a time-consuming purge-and-clean cycle
Retains approximately 55 to 85 PSI (3 to 6 bar) pressure, maintaining the integrity of the cylinder contents against contaminants, even if the valve is left open
Protects and extends life of cylinder by preventing ingress of moisture
Pressure Relief Device (PRD) unitized plug design provides excellent flow characteristics
Dynamic front piston seal design is not in direct contact with the flow passage during filling
Inlet and outlet thread configurations are available for a broad spectrum of customer, country and code specifications
Optical Character Recognition technology utilized to verify appropriate burst disc pressure rating
Exclusive “webbed washer” design protects burst disc during handling and bulk shipment
