Servo converter SVA9 is a high-reliability moving coil type electric-displacement proportional conversion element, mainly used in steam turbine, gas turbine or water turbine electro-hydraulic speed control system.

 

Servo converter SVA9 is an improved version of SV9, which was successfully developed in the early 1990s. It is an anti-pollution electro-hydraulic converter designed for the power station speed governor industry. It can convert weak electrical signals into displacement outputs with considerable force through hydraulic amplification, thereby realizing automatic and precise position control of the actuators (such as oil motors, steam inlet valves, fuel regulating valves, relays or water inlet valves, etc.) of steam turbine, gas turbine or water turbine electro-hydraulic speed governors, so as to achieve the purpose of controlling the speed and load of the unit.
