Electro-hydraulic actuator

CDG Electricity Hydraulic actuator, small installation space, no external hydraulic station, oil pipeline, control box, electric cable, on-site installation at any angle, combined with valve computer remote simulation debugging factory, reduce on-site debugging costs and potential problems. This product technology leads the domestic industry, widely used in petroleum, chemical, metallurgy, power, light industry, shipbuilding, building materials city treatment and other process pipelines, to implement regulation or rapid cut-off control.

According to the valve's transmission method, there are 0 ~ 90 ° rotary motion and linear motion, which can form two major categories of actuators: 1. Rotary electro-hydraulic actuator (regulating and switching type) 2. Linear electro-hydraulic actuator (regulating and switching type).

Many valve conditions require automatic reset in case of failure or power failure, which can form two major categories of actuators: 1 ，General automatic reset ( 1 ~ 4 seconds, regulating and switching type), 2 Fast reset ( 0.5 seconds, regulating and switching type)

Hydraulic check valve is suitable for pump outlet pipelines with water as the medium, used to avoid and reduce the backflow of the medium in the pipeline system and generate excessive water hammer, to protect the pipeline system, its function is to replace two valves with one valve, this condition can form two major categories of actuators: 1 ，Full hydraulic accumulator type electro-hydraulic actuator (rapid closure and slow closure interlock type), 2 ，Semi-hydraulic check valve accumulator type (using spring compression mechanical energy), forming a single-acting electro-hydraulic actuator (replacing heavy hammer type).
