About On/Off Valves
More
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.
316 stainless steel valves resist corrosion better than brass and steel valves.
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.

On/Off Valves with Yor-Lok Fittings
For extra gripping power and a strong seal, the Yor-Lok fittings on these valves have 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.
316 stainless steel valves are more corrosion resistant than plain and nickel-plated 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.

Drainage Valves
Also known as stop cocks, install these valves on your tank for easy draining.
Valves with external seal are for higher flow applications than valves with an internal seal.
