Profile: Zhejiang Regis Machinery Co., Ltd. is a supplier of air cylinders, solenoid valves, air source treatments, couplings, connectors, and other related accessories. Directional valves are available in two-way & three-way configurations in port sizes from M5 to 1/2". We offer direct-acting poppet or solenoid-controlled pilot operated balanced spool design. Spool valves are body ported, but can be bolted to a parallel circuit manifold. These electronic valves offer high flow in a small package, and are constructed of aluminum, stainless steel, and thermoplastic materials. The four-way valves are also available in 3 position versions with either pressure center, closed center, or exhaust center spool options.
