About On/Off Valves

Panel-Mount Threaded On/Off Valves

Control the flow of your line while it’s protected behind an instrument panel. These valves have threads and a hex nut below the handle, so it sticks out of your panel for access.
Full-port valves do not restrict flow.
Standard-port valves slightly restrict flow.
316 stainless steel valves are more corrosion resistant than brass valves.
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.

Panel-Mount On/Off Valves with Yor-Lok Fittings

Easily access the handle of these valves while protecting your line behind an instrument panel. Threads and a hex nut below the handle allow you to install these valves in instrument panels. For extra gripping power and a strong seal, they have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. Valves are standard port, so they slightly restrict flow.
Valves with lockable handle can be fixed in place using a padlock (not included).
316 stainless steel valves are more corrosion resistant than brass valves.
Fluoroelastomer seals are highly compressible, so they conform to connections to make tight seals, even when surfaces are uneven, misaligned, and dirty.
PTFE seals are the best choice for valves that are opened and closed often. The PTFE material forms a seal while remaining slippery, so you can open and close the valve frequently without the seal wearing down and failing.
PFA seals withstand high pressures and temperature changes. The plastic of the seal is nonporous, so it won’t trap gases or liquids that would weaken these seals.
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.

Panel-Mount Threaded On/Off Valves for Drinking Water




- Valve Type: Ball
- For Use With: Drinking Water
- Seal Material: EPDM Rubber
- Specifications Met: NSF/ANSI 61
Protect your drinking water line behind an instrument panel while keeping the handle handy. These valves have a nut that threads onto the stem to mount the handle onto the panel. They meet NSF/ANSI 61, a strict standard for drinking water systems.
PVC valves are the most common for drinking water systems.
Polypropylene valves are more flexible than PVC valves, so they’re better at handling movement and vibration without cracking.
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.

Panel-Mount Threaded Diverting Valves
For installation in instrument panels, these valves have threads and a hex nut below the handle. They divert flow between ports. Turn the handle to direct the flow.
Full-port valves do not restrict flow.
Standard-port valves slightly restrict flow.
Valves with a 316 stainless steel body are more corrosion resistant than those with a brass body.
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.

Diverting Valves with Yor-Lok Fittings

- Valve Type: Ball
- For Use With: Air, Argon, Helium, Krypton, Neon, Oil, Water, Xenon
- Seal Material: See table
For extra gripping power and a strong seal, these valves have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. Valves divert flow between ports. Turn the handle to direct flow from the bottom-port inlet to either side-port outlet. Valves are standard port, so they slightly restrict flow. All have threads and a hex nut below the handle for panel mounting.
Valves with flow shut-off can stop flow completely in addition to diverting flow between outlet ports.
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.

NFPA Valve-Mounting Blocks







NFPA valve-mounting blocks have standardized valve mounting patterns to keep hydraulic lines compact and organized.
NPTF (Dryseal) threads are compatible with NPT threads. UN/UNF (SAE Straight) thread connections have straight threads and are also known as O-ring Boss fittings.

Directional-Control Inline Hydraulic Valves



Turn the handle to direct flow between ports. All valves are standard port, so they slightly restrict flow.
In NFPA diagrams, P represents the pressure source, T represents the tank, and A represents the work port.
