SE3 Servo cartridge valve Size 30, 50 & 63 2
Servo valve for manifold mounting
Continuously adjustable flow from P to A or A to T;
Pilot valve (1) located directly on the cover (4).
Technical design
The valve comprises of 6 main groups:
Pilot valve (1)
Main stage spool (2)
Sleeve (3)
Cover (4)
Position transducer (5)
Integrated control electronics (6)
Function description
- Main stage spool (2) with equal pilot-surfaces.
- Controlled by a high-dynamic proportional-pilot valve (D633).
- Pressure balance through the drilling (7) in the main stage spool (2), resulting in a very low
displacement force.
- Control of the main flow from P to A or A to T by the spool lands (8).
- Control of the main stage spool by a position transducer (5).
- Closed loop by integrated electronics (6).
- Failsafe features: => Fail-safe sandwich plate or biased pilot valve, see on page 13.
Recommendation: For application where vibrations shocks higher than 30g are expected, the
electronics with additional dampening elements are required. (see “ES” in the
Ordering Information)
Attention: Wrong connecting leads to uncontrolled movements of the main stage spool and
may cause damage to person and machine!
