WRCE | Directional high-response cartridge valve Function, section: "2WRCE" Valves of type 2WRCE are pilot-operated, 3-stage directional high-response cartridge valves. They control the quantity and direction of a flow and are mainly used in control loops. Set-up The valves consist of the following assemblies: ▶ 2-stage pilot control valve (1) – with dry torque motor – low-friction nozzle flapper plate amplifier – mechanical feedback of the control spool position ▶ Main stage (2) for flow control ▶ An inductive position transducer (3) the core (4) of which is attached to the main control...
