MB Series valves are designed for the actuation of small air cylinders and clamps, and are suited for applications requiring low air flow. For manifolding, 2 or 3 station bases are offered. Manifolds can be bolted together to provide the desired banking combination. The valves are direct acting, multipurpose valves with all ports in the body. The valve body is molded from plastic, while the internal parts are nylon, polyester and stainless steel. The valves will operate at up to 150 PSI, consuming only 4 watts per coil on AC operation, 5 watts per coil on DC. Functional design flexibility is assured given the wide variety of available valve configurations. The listed accessories enable the user to customize MB Series valves as 2-way normally open or normally closed by plugging one port; 3-way normally open, normally closed or directional control.
