Voith electro-hydraulic way valves are servo directional control valves. They have integrated position control and provide direct control of hydraulic positioning cylinders. The positioning cylinders operate a valve that controls the mass flow needed to drive machinery. Voith way valves ensure very precise and high dynamic control of the mass flow. Working in conjunction with a hydraulic cylinder, the way valve converts a constant input pressure into a variable stroke. A standard 4 – 20 mA signal specifies the stroke of the positioning cylinder. The major components of a way valve are a 3/3 way hy­draulic unit for single-acting positioning cylinders or a 4/3 way hydraulic unit for double-acting positioning cylinders and a force-controlled electromagnet with integrated position control. An additional pilot valve is not needed with the Voith electrohydraulic way valve. The way valve features a simple, compact design. This ensures consistent, reliable operation. The Mean Time Between Failures (MTBF) for Voith way valves is over 180 years. Your equipment runs for a very long period of time without unplanned down­time. Availability is increased. The way valve is available in two redundant designs: T-WSR Tandem Way Valve (Dual Coil Way Valve) with redundant control magnets (cold redundancy) WSM Way Valve Module (hot redundancy)
