Residual Pressure Valves

Protects cylinders and contents from back flow of contaminates. Used specifically with high pressure steel and aluminum cylinders. Retains small amount of filled gas (approximately 55-85 PSI) to ensure purity inside vessel. Valves are available in CGA-320 and CGS-580 models.

Key Features

  • Durable forged brass body with precisely machined internal components
  • Unitized plug design provides excellent flow characteristics
  • Dynamic front piston seal design avoids direct contact with flow passage during filling
  • Various inlet and outlet thread configurations available
  • 100% helium leak tested
  • Meets stringent international valve performance standards

Benefits

  • Prevents back flow of contaminates and foreign substances
  • Maintains integrity of contents, even if valve is left open
  • Retains small amount of filled gas (approximately 55-85 PSI) to ensure purity inside vessel
  • Eliminates expense of a time-consuming purge-and-clean cycle
  • Protects and extends life of cylinder by preventing ingress of moisture

Pin Adapters ‒ Retractable & fixed

Pin Adapters provide maximum operating flexibility to fill or evacuate a cylinder with either a conventional valve or an RPV.
The adapters incorporate an O-ring seal for a hand-tight connection.
