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.

Threaded On/Off Valves
Use these valves in general purpose applications such as those with water, oil, air, and inert gas.
Short lever handles, lockable oval handles, and T-handles resist accidental movement when snagged or bumped.
Full-port valves do not restrict flow.
Standard-port valves slightly restrict flow.

Threaded On/Off Valves with Easy-Access Strainer
A built-in strainer traps debris and allows you to replace the screen without disconnecting your pipeline. These valves have a T-handle or lever that resists accidental movement when snagged or bumped. They are full port, so they do not restrict flow.
Nickel-plated brass valves are more corrosion resistant than plain brass valves.

Compact Threaded On/Off Valves for Chemicals
For chemical-processing applications in confined areas, these valves have a low-profile handle to fit in tight spots. A rubber seal and a plastic body stand up to aggressive, corrosive solutions.
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.
