High-Pressure Compact Threaded On/Off Valves
These valves handle twice the pressure of other compact valves. Install them in tight spots, such as where pipelines are crowded together. They’re roughly half the height and length of standard threaded valves.
Brass valves resist corrosion better than steel valves. 316 stainless steel valves resist corrosion better than brass and steel valves.
Lever handles are easy to open and close—they give you the most leverage of any handle type. Lockable handles can be fixed in place using a padlock (not included).
Full-port valves do not restrict flow. Standard-port valves slightly 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.

Compact Threaded On/Off Valves
Install these valves in tight spots, such as where pipelines are crowded together. They’re less than half as long as standard threaded valves and one-third shorter in height.
Bronze valves are stronger and more durable than brass valves. Chrome-plated brass valves are more corrosion resistant than plain brass and bronze valves. Short-lever handles and T-handles resist accidental movement when snagged or bumped. Lever handles are easy to open and close—they give you the most leverage of any handle type.
Screwdriver-operated valves are our most compact option. Since they open and close with a slotted screwdriver (not included), they’re also the most resistant to accidental movement.
Valves with threaded outlets can connect to pipe or hose, giving you more control over where your fluid flows than valves with a drain or spout outlet.
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.
