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
