NG10 - Proportional directional valves

DKZO proportional valves cetop05 type, direct operated, which provide both directional and non-compensated flow control according to the electronic reference signals. They operate in association with electronic drivers, which supply the proportional valves with correct current signal to align valve regulation to the reference signal supplied to the electronic driver (which may be integral or Eurocard type).

These valves have a 4-way spool, sliding into a 5-chambers housing and directly operated by ZO solenoids. To compensate flow variations due to pressure variations, modular pressure compensators are available to keep a constant pressure drop across the spool.

The coils are fully plastic encapsulated (insulation class H) and valves have antivibration, antishock and weatherproof features.

Version DKZORA = without integral transducer. Spooltype S = Progressive. Version /B: Solenoid at side of port A.

Max. flow mentioned is at 30 bar differential pressure across the valve.

Max. working pressure: Port P, A and B: 315 bar Port T: 160 bar (250 bar with external drain, port /Y).

Recommended viscocity: ISO VG 15 - 100 (at 40°C).

Temperature range: -20°C to +60°C. (with standard seals. Up to +80°C if PE-seals are used).

Fluid contamination class: ISO 18/15 (with filters nom. 10my and ß10 larger than or equal to 75).

On request avaiable with seals for non-flammable fluids as water-glycol (/WG) or phosphate esters (/PE).
