Description

Way Valve Module, Redundant Way Valve, Redundant Proportional Directional Control Valve Voith way valve modules are redundant proportional directional control valves. They have integrated position controls and provide direct control of hydraulic positioning cylinders in processes re­quiring high availability. The positioning cylinders operate a valve that controls the mass flow needed to drive ma­chin­ery. Voith way valves ensure very pre­cise and highly dynamic control of the mass flow. A way valve module consists of two way valves connected in parallel. 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 the way valves are a 3/3 way hy­draulic unit for single-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 module. Every way valve has a monitoring circuit that detects malfunction of a way valve. In the event of way valve malfunction, a hydraulic maximum selection circuitry ensures that the other way valve assumes control. This makes it possible to remedy the cause of the malfunction during operation. The Mean Time Between Failures (MTBF) for Voith way valve modules is over 8,800 years. Your equipment runs for a very long period of time without unplanned down­time; availability is increased.
