Electrohydraulic drive EGP-01 is designed for controlling ball valves in explosion-hazardous zones of premises and exterior installations.
The device is used as a part of telemetry systems (complexes) for control of valves with nominal pipeline diameter DN300-DN1400 (the device model depends on maximum torque of a ball valve on which an electrohydraulic drive is installed).
The electrohydraulic drive EGP-01 is designed for creating and using hydraulic liquid pressure to control opening and closing a ball valve or other pipeline valve.
The device with included limit switch assembly provides 90° valve turn.
The drive is powered by hydraulic liquid pressure created by a hydraulic pump and pressure energy stored in a hydraulic accumulator. Pressurized hydraulic liquid is fed to a hydrocylinder, which turns the ball valve. In case of power supply outage, EGP-01 is powered by hydraulic liquid energy stored in a hydroaccumulator or with a manual backup (manual pump).
The operating medium used in the hydroaccumulator is an inert gas – nitrogen. During the operation, it is possible to control pressure and refueling of the hydroaccumulator with gas.
Gas production, storage and preparation facilities in gas well clusters, main gas and oil pipelines.
Work in harsh climate conditions (environment temperature from -61°C to +60°C);
remote control of the process equipment and communication with the telemetry system;
24 V power supply from an autonomous electric complex;
possible operation with no power supply;
communication with the telemetry system through RS-485 digital interface;
designed for operation in explosion-hazardous zones.
