R-331 is a dual element combination consisting of a fully ported, spring return, 3-way valve, and an adjustable flow control to provide a delay “IN” function. Input signal at port 4 will be delayed through adjustable flow control and will delay the actuation of the valve. The 3-way valve is fully ported and can be used normally-OPEN, normally-CLOSED, or as a selector or diverter. Port 7 is an auxiliary for adding volume for longer time delays. If not used, port 7 should be plugged.
