Gas Check Valves

Gas Check Valves

Self activating safety valves that stop the backflow which protects the equipments and mechanical devices from sudden backflow surge is made by Rego/Goddard Valve, a  world leaders in valve manufacturing.  Applying the latest technology, Rego/Goddard Valve Check valves are designed to suit a wide range of applications to meet all your check valve needs, be it for gas check valves, cryogenic check valves or internal check valves for CO2 services.

 

Design benefits of Sherwood Check Valves

 

  • Swing check valves made from bronze or stainless steel allow smooth flow and automatically close when the pressure decreases and fully closes when the flow reaches zero
  • The valve is designed as a disk and hinge with the hinge being suspended from the hinge pin which is on the body
  • The seating is made from either metal to metal or metal seat to composition disk
  • The swing check valve is in a Y-pattern with the closure element attached to the top cap
  •  Rego/Goddard Valve check valves, cryogenic check valves, CO2 service check valves permit easy opening at low pressures
  • Less shock when closing under high pressure
  • Turbulence and drop in pressure is very low
  • Rego/Goddard Valve Lift Check Valves have a similar seating pattern like Rego/Goddard Valve Globe valves
  • The pressure of upward flow opens the disc, the disc falls when flow is reversed
  • The valve stopper operates silently as it uses a spring and bushing system
  • Internal valves for CO2 service can be operated manually or pneumatically

 

Specific usage of Rego/Goddard Valve Check Valves

 

Rego/Goddard Valve swing check valves should be used in systems that use gate valves. The design of the disk valve is such that it is recommended to use this check valve for media that has particles present in it. Sherwood check valves are used in cryogenic gas lines as well as CO2 service to stop the backflow and protect rotating equipments and mechanical devices.

Rego/Goddard Valve internal valve for CO2 service are designed for use with withdrawal of the liquid from delivery trucks, transports, storage tanks and inline installation.
