GAS CYLINDER VALVES 3/4″ -14 NGT – ARGON, HELIUM, NITROGEN
This DSW 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.

PREMIUM CONSTRUCTION
Heavy-duty forged brass body for durability and high pressure
Precisely machined internal components meet the most stringent international valve performance standards
Metal-to-metal seal below bonnet threads prevents pressure in the threads at top of valve body

GAS CYLINDER VALVES
Pressure relief device
Automated assembly and testing processes ensure exceptional quality
100% helium leak tested
Pressure Relief Device (PRD) is a unitized plug design that provides excellent flow characteristics, ensures proper assembly and tamper resistance
Direct-drive stem design with optimized O-ring or double O-ring seal reduces friction and operates at exceptionally low torque levels
Tapped for dip tube as required
