Digital servo proportional directional, direct operated valves with LVDT position transducer and zero-spool-overlap, for position control in a closed-loop. The valve's double-solenoid construction allows its application with larger flow rates and provides a central safety rest position.
TEB - basic execution with analog reference signals, and a USB port for software's functional parameters' setting.
TES - full execution, which includes optional alternated P/Q control, and Fieldbus interface for functional parameters' setting, reference signals, and real-time diagnostics.
The digital version TEZ integrates an on-board driver and axis card, while TEB and TES versions are applicable in combination with Z-BM-KZ off-board axis card.
DHZO: Size: 06 Max flow: 80 l/min. Max press: 350 bar.
DKZOR: Size: 10 Max flow: 180 l/min. Max press: 315 bar.
Servo proportional directional, direct operated valves with LVDT position transducer and zero-spool-overlap, for best performance at any position in a closed-loop. LVDT transducer and sleeve execution ensure high regulation accuracy and response sensitivity.
The "fail-safe" position allows intercepting an actuator's movement, in case of power supply interruption.
Spool's regulation characteristics - L - linear; V - progressive; T - non-linear, for low-pressure control; D and DT - differential, for control of actuators with area ratio 1:2.
DLHZO: Size: 06 Max flow: 70 l/min. Max press: 350 bar.
DLKZOR: Size: 10 Max flow: 160 l/min. Max press: 315 bar.
Digital servo proportional directional, direct operated valves in sleeve execution with LVDT position transducer and zero-spool-overlap, for best performance at any position in closed-loop control.
Proportional directional pilot operated valves with two LVDT position transducers and positive spool-overlap for directional control dynamics and not compensated flow regulation.
The LVDT transducers (pilot and main stage) ensures high regulation accuracy and response sensitivity. With de-energized proportional solenoids, mechanical central positioning of the spool is performed by centering springs.
Spools regulation characteristics - L - linear; S - progressive for low flow control; D and DL - differential, for control of actuators with area ratio 1:2; D9 and L9 - for the regenerative circuit; Q5 and V9 - for P/Q control.
Size: 10 ÷ 32
Max flow: 180 ÷ 1600 l/min.
Max press: 350 bar.
Digital, servo proportional, directional, pilot operated valves, with two LVDT position transducers, and zero-spool-overlap, for position control in a closed-loop.
LEB - basic execution, with analog reference signals, and USB port for software functional parameters' setting.
LES - full execution, which includes optional alternated P/Q controls, and Fieldbus interface for functional parameters setting, a reference signal, and real-time diagnostics.
The digital version, LEZ, integrates an on-board driver and axis card, while LEB and LES versions are applicable in combination with Z-BM-KZ off-board axis card.
Size: 10 ÷ 35
Max flow: 180 ÷ 3500 l/min.
Servo proportional 3-way cartridge valves, designed for high-speed control in a closed-loop. Two LVDT transducers (pilot and main stage) ensure high-accuracy regulation and response sensitivity; the cartridge execution, for installation in blocks, allows high-flow capabilities and minimized pressure drops.
Spool's regulation characteristics - L - linear.
LIQZO: Size: 25 ÷ 40 Max flow: 500 ÷ 1050 l/min. Max press: 350 bar.
LIQZP: Size: 50 ÷ 80 Max flow: 2000 ÷ 5000 l/min. Max press: 420 bar.
Digital servo proportional 3-way cartridge valves, designed for high-speed control in a closed-loop, equipped wit two LVDT position transducers for best dynamics of directional control, and not compensated flow regulation; cartridge execution, for installation in blocks, allows high-flow capabilities and minimized pressure drops.
High-response, 2-way servo proportional, cartridge valves, designed for dynamic and accurate control. LIQZH valves are typically applied in die-casting, and fast-forging processes. LIQZH valves are equipped with two LVDT position transducers, for dynamic regulation of not compensated flow. Cartridge execution, for installation in blocks, allows high-flow capabilities and minimized pressure drops. Valve's hydraulic regulation is performed by the integral digital electronic driver following the reference signal, assuring the valve-to-valve interchangeability, due to the factory's presets.
LEB - basic execution, with analog reference signals, and USB port software functional parameters setting. LES - full execution, which includes optional Fieldbus interface for functional parameters' setting, reference signals, and real-time diagnostics.
Size: 32 - 100 Max flow: 1800 - 16000 l/min. Max press: 420 bar.
