The 4-in-1 drip valve is a combination automatic jar-top valve, filter, pressure regulator, and drip adapter for micro watering applications where clean water and low pressure are important for optimum performance. It is also called a “drip control zone.” It is compact enough to fit four valves side-by-side in a standard rectangular valve box using a manifold. The valve features an easy-to-service jar-top design, a 24 VAC solenoid, manual actuation lever, and bleed screw. The filter is made from fine 120-mesh stainless steel and has a flush port on the top for easy cleaning. The compact pressure regulator reduces pressure to 30 PSI while maintaining flow up to 10 gallons per minute (GPM). Both the inlet and outlet are 1-in. male pipe thread (MPT). The Drip-Lock adapter connects to 17mm or .700-in. drip blank distribution tubing. The 4-in-1 valve is compatible with all major brands of 24 VAC irrigation controllers. We recommend B-hyve controllers for optimum water conservation. For outdoor irrigation use with cold water only.
