Servo Directional Control Valve with Redundant Control Magnet Unit (Dual Coil System) Tandem Way Valve Type T-WSR Voith tandem way valves are way valves with two control magnets (dual coil system). The control magnets are connected in series and create a redundant unit. Tandem way valves with integrated position control adjust hydraulic positioning cy­lin­ders by means of a pilot valve in processes requiring high availability. The positioning cy­linders operate a valve that controls the mass flow needed to drive machinery. Voith tandem way valves ensure very precise and high dynamic control of the mass flow. A tandem way valve consists of two electromagnets with integrated position control connected in series and a 3/3 way hydraulic unit for single-acting positioning cylinders or a 4/3 way hydraulic unit for double acting positioning cylinders. 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. An additional pilot valve is no longer needed with the Voith electrohydraulic tandem way valve. In the event of a malfunction, control magnet 1 switches off automatically and control magnet 2 switches on. The switching logic is located in the external control system and monitors the control magnets. The Mean Time Between Failures (MTBF) for Voith tandem way valves is over 360 years. Your equipment runs for a very long period of time without unplanned down­time; productivity is increased.
