Directional valve size NG 16 WL 4.16 Installation dimensions ISO 4401 / DIN 24340 A16 electro-hydraulically pilot operated

 Open the catalog to page 1

Directional valve size WL 4.16 Installation dimensions ISO 4401 / DIN 24340 A16 A pilot valve operates the main control valve electrohydraulically. For operating the pilot valve, pressure-tight direct and alternating current magnets can be fitted switching in oil. The control piston for the main control valve is operated by the flanged pilot valve directly subject to actuating pressure and switched to indexing position a or b. The buncher space or spring chamber is formed by two flanged covers that can also be fitted with a stroke limiter. The control oil in- and outlet can be individually switched...

Directional valve size WL 4.16 Installation dimensions ISO 4401 / DIN 24340 A16 Control oil in- and outlet Counterbalance valve in connector P Counterbalance valves are used for valves with pressure-free circulation and internal withdrawal of control oil. The counterbalance valve also functions as a check valve in connector P. Ordering code: 3301121/4 Check valve in connector P A check valve can be built into connector P in order to prevent volume displacement from the client to connector P when activating statically loaded clients. Ordering code: 3301122/4 A check- or counterbalance valve can...

Q (Qmax.) [l / min] at . The flow rate Q = 250 l/min is a recommended rate. This can be up to Q = 300 l/min taking account of higher flow resistance. . In the case of pressure flow rate values above the values stated and the flow resistance of subordinate importance (see Äp-Q-characteristic curve), the pressure-centred recirculation is to be used (on request).
