EMG Servo Valve Type SV1-10

A torque is produced at the armature by a direct control current in the exciter windings. The size and direction of this torque are proportional to the control current and turn the armature, against the force of the centring springs, from its neutral position. As a result, the rotary slide fixed on the same shaft is also rotated; the blind holes in it create a continuously increasing connecting area between circular duct sections and consumer connections. The rotary slide, enclosed by its sealing cover, floats at a defined leak gap Y1 on an oil film, above the leading edge sealing surface.

Technical features

• temperature- and pressure-independent zero point stability
• practically constant dynamics (almost independent of pressure and drive)
• large control distances, long service life, low leakage flow
• mechanical manual/emergency control and external performance monitoring
• spring-centred rotary slide (zero position in the event of an electrical power failure)
• standard connections, standard plug

Customer benefits

• cleaning flush of the valve during operation
• also suitable for low pressure levels
• single- and double-stage construction possible (SV1-.../SV2-...)
• guaranteed minimum friction losses
• high repetition accuracy
• huge range of performance for single- and double-stage valves
• high level of reliability
• extremely easy to service
