On/Off Valves with Barbed Fittings
These valves have barbs that grip onto tubing, providing a secure hold.
Nickel-plated brass valves are more corrosion resistant than plain brass valves.
316 stainless steel valves have the best corrosion resistance.
T-handle valves resist accidental movement when snagged or bumped. They are also known as stop cocks.
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.
