Gems Sensors Solenoid Valve Manifolds are 303 stainless steel manifolds that can be used with any Gems solenoid valve manifold mount type A Series or B Series valves. Specify the "MM3" Body Port Configuration code when ordering valves to mate with these manifolds. To complete a solenoid valve manifold assembly please order a manifold and then order the valves separately. Valves screw easily onto the manifold. If needed, a spanner tool for installing the valves is available in the Ordering Table. Blank plugs to block off unused ports, with a variety of O-ring material options, are also available. Typical applications for Gems Sensors Solenoid Valve Manifolds include: thermal control, waste handling, gas delivery, liquid delivery, fluid mixing and inventory management systems.
