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.

On/Off Valves with 37° Flared Tube Fittings for Fuel

- Valve Type: Ball
- For Use With: Diesel Fuel, Fuel Oil, Gasoline
- Seal Material: PTFE Plastic
These valves have 37° flared tube fittings that form a tight seal on metal tubing lines to transfer diesel fuel, fuel oil, and gasoline. All are full port, so they do not restrict flow.

On/Off Inline Hydraulic Valves

Start and stop flow with a quarter turn of the handle. Valves are full port, so they do not restrict flow.

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.

International Standard ISO B Quick-Disconnect Hose Couplings for Hydraulic Fluid

A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them if you need frequent access to a hydraulic hose line. All of the International Standard ISO B quick-disconnect plugs are compatible with any of the International Standard ISO B quick-disconnect sockets of the same coupling size, regardless of the pipe size. Couplings meet ISO 7241-1 Series B dimensional and performance standards and are compatible with Parker 60 couplings. Also known as double shut-off couplings, the plugs and sockets both have a shut-off valve that stops the flow when the coupling is separated.
Plugs are also known as nipples.
Sleeve-lock sockets connect by sliding back the sleeve on the socket, inserting the plug, and releasing the sleeve. To disconnect, slide the sleeve back and pull out the plug.
Zinc-plated steel is stronger and more durable than other metals. It has fair corrosion resistance.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings are given for static (constant) pressure conditions.
Warning: Never attempt to connect or disconnect couplings when operating at maximum pressure. Stop the flow before you disconnect the line.
