Description Size 32 … 50 Component series 2X Maximum operating pressure 420 bar Maximum flow 2200 l/min Features 3-way directional cartridge valve Pilot control valve: 2-stage directional servo valve Main stage: position-controlled Flexible: – Suitable for position, pressure, force and velocity control Typical applications: - Presses - Die casting machines - Nibbling axes Product description Valves of type 3WRCE 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 spool (5) of the third stage Integrated electronics (6). Function The integrated electronics compares command and actual values and the torque motor of the pilot control valve is actuated with a proportional current according to the control deviation. The pilot control valve (1) takes a proportionally controlled position and controls the flow in and out of the control chambers A (7) and B (8) that actuate the main control spool (5) through the closed valve control loop up to 0 control deviation. This means that the stroke of the main control spool (5) is regulated proportionally to the command value. It must be noted that the flow also depends on the valve pressure drop. Valve features The opening point of 0% (symbol V) is set at the factory. Upon replacement of the pilot control valve (1) or the control integrated electronics (6), the opening point can be readjusted using the zero adjustment potentiometer R316 (accessible via a plug screw). During the exchange, no settings must be made at the control electronics (= controller or control electronics) and the pilot control valve (1), except for the zero adjustment at the position transducer. At the pilot control valve (1), only the filter element may be exchanged. The pilot control valve (1) is trimmed so that the pilot pressure is connected to control chamber B (8) in case of a power failure, i.e. the main stage opens from A to T and/or closes the connection from P to A. The spring behind the main control spool (5) moves it into position so that P to A is closed if no pressure is applied (e.g. prior to installation, before the pressures are reapplied after tool change). The integrated electronics (6) features an offset to compensate the trimming (pilot trimming) of the pilot control valve (1). Notice: Version "3WRCE" is not recommended for new applications. If version "3WRCE" is used, ports A and P have to be exchanged. Upon request.
