Sherwood Inert Gas Valve – CGA580, 1.125″ UNF – Argon, Helium, Nitrogen

This Sherwood inert gas valve is made from heavy-duty forged brass and is specifically designed for use with argon, helium, or nitrogen in steel inert gas cylinders. Common applications include welding and other industrial uses. This inert gas valve has a CGA580 valve outlet with a 1.125″ UNF inlet and safety (burst disk).

Premium Construction

  • Automated assembly and testing processes ensure exceptional quality
  • 100% helium leak tested
  • Heavy-duty forged brass body for durability and high pressure
  • Precisely machined internal components meet the most stringent international valve performance standards
  • Pressure Relief Device (PRD) is a unitized plug design that provides excellent flow characteristics, ensures proper assembly and tamper resistance
  • Metal-to-metal seal below bonnet threads prevents pressure in the threads at top of valve body
  • Direct-drive stem design with optimized O-ring (GSV) or double O-ring (GSHV) seal reduces friction and operates at exceptionally low torque levels
  • Inlet and outlet thread configurations are available for a broad spectrum of customer, country and code specifications
  • Tapped for dip tube as required
