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.
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 with Gauge Port
- Valve Type: Ball
- For Use With: Air, Water
- Seal Material: Fluoroelastomer Rubber
- Specifications Met: C-UL Listed, CSA Certified, CSA-US Certified, UL Listed
Attach a gauge to the side port on these valves to monitor pressure, temperature, and other measurements in your line. The port can also be used to drain and divert liquid. These valves are full port, so they do not restrict flow.
Lever handles are easy to open and close—they give you the most leverage of any handle type.
Short-lever handles and T-handles resist accidental movement when snagged or bumped.
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.

Compact Threaded On/Off Valves
Install these low-profile valves in tight spots.
Chrome-plated brass valves are more corrosion resistant than brass and bronze valves.
Short lever handles, T-handles, and screwdriver-operated handles resist accidental movement when snagged or bumped.
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.

Easy-to-Install Plastic Threaded On/Off Valves
A threaded union on these valves makes them easy to install and remove without disrupting your line. They’re a good choice for lines that require frequent maintenance or cleaning. They thread together or apart with only a turn to the union fitting, unlike other threaded on/off valves that require repositioning your pipe or valve. The union fitting slides over your pipe, and the threaded fitting sits inside. With a full port, these valves won’t restrict flow.
Made of plastic, they last longer than metal valves since the inside won’t corrode or pit. They’re also lighter in weight. Polypropylene valves are our most flexible option, so they’re best at handling movement and vibration without cracking.
Valves with a short lever handle are smaller than valves with a T-handle, so they’re better for low-clearance lines.
