Servo-proportional directional valve – DLHZO-T, DLKZOR-T

Direct-acting servo-proportional directional valves in a sleeve design, with LVDT position transducer and zero-overlap spools to ensure the best performance in any closed-loop position control. The valves operate in combination with separate digital drivers or digital axis cards, see section . The LVDT transducer and sleeve design ensure very high control precision and response sensitivity. The fail-safe function allows the actuator movement to be intercepted in the event of a power failure. Spool control characteristics: L = linear V = progressive T = non-linear, for precise low-flow control D and DT = differential, for the control of actuators with a 1:2 area ratio DLHZO: DLKZO.
