Butt-Weld On/Off Valves
- Valve Type: Ball
- For Use With: Argon, Helium, Krypton, Neon, Oil, Steam, Water, Xenon
- Seal Material: PTFE Plastic
Weld these valves to unthreaded metal pipe for a permanent, flush connection that permits smooth flow through a line. To access internal components without disturbing welded connections, disassemble the three-piece bolted body inline. Valves are cleaned and bagged for high-purity applications such as oxygen service. All have a 316 stainless steel body for excellent corrosion resistance. The lockable lever handle can be fixed in place using a padlock (not included) with a shackle diameter up to 5/16”. These valves are full port, so they do not restrict flow.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

On/Off Valves with Butt-Weld Fittings for Food and Beverage
- Valve Type: Ball
- For Use With: Food, Beverage
- Seal Material: PTFE Plastic
Weld these valves to unthreaded metal pipe for a permanent, flush connection that permits smooth flow through a line. For easy cleaning in food and beverage systems, they have polished internal surfaces and a three-piece bolted body that disassembles inline for access to internal components without cutting welded connections. All valves have a lockable lever handle that can be fixed in place using a padlock (not included). They are full port, so they do not restrict flow.
