Product Details
The 1/2 pipe, 501-4AA Series piston-poppet, 4-way air piloted valve achieves high flow from a compact body. Incorporates an internal compensating orifice to achieve faster response, or a "momentary signal, maintained position" function. Excellent choice to operate large double acting pneumatic cylinders (up to 8" bore) in poor media, difficult environments. Mounting feet standard.
