About On/Off Valves

Threaded On/Off Valves
Use these valves in general purpose applications, such as those with water, oil, air, and inert gas.
Bronze valves are stronger and more durable than brass valves for a longer service life. Full-port valves 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.

- Valve Type: Ball
- For Use With:
NPT: Argon, Helium, Krypton, Neon, Oil, Steam, Water, Xenon
BSPP and BSPT: Air, Argon, Helium, Krypton, Neon, Oil, Steam, Water, Xenon
UN/UNF: Air, Argon, Oil, Steam, Water - Seal Material: PTFE Plastic
Lever handles give you the most leverage for quickly opening and closing valves with minimal effort.

Lockable On/Off Inline Hydraulic Valves

Lock the handle using a padlock. When unlocked, a quarter turn of the handle starts and stops flow. Valves are full port, so they do not restrict flow.
UN/UNF (SAE Straight) thread connections have straight threads and are also known as O-ring Boss fittings.
