Control the flow of chemical solutions from any garden hose. With a fluoroelastomer seal and polypropylene body, these valves withstand strong chemicals, such as chlorinated water and phosphoric acid. This makes them a great choice for lines used to spray greasy floors with cleaning solutions or to spread fertilizer. These valves have garden hose threads, which are a standard size, so they’re compatible with all standard garden hoses. When open, these valves don’t restrict the flow—they’re full port.
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.
