Often used in HVAC or refrigeration systems, these valves are designed to control the flow of ammonia, nitrogen, and other harsh chemicals. To prevent accidental spills, a spring on the handle will automatically close the valve if you lose your grip. It’s also known as a deadman’s handle. The ball has a vent to relieve gas buildup when the valve is closed. Made from 316 stainless steel, these valves have excellent corrosion resistance.

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.
