Hydraulic Actuated Gate Valve

What is Hydraulic gate valve？

Hydraulic Actuated Gate Valve is a type of valve that uses hydraulic power to control the opening and closing of the gate. The gate valve has a gate or a wedge that moves up and down to open and close the valve. The hydraulic actuator provides the force required to move the gate or wedge.

Hydraulic Actuated Gate Valves are commonly used in industries that require high-pressure fluid or gas flow control, such as oil and gas pipelines, petrochemical plants, power plants, and water treatment facilities. They are preferred in applications where the valve needs to be operated remotely or in hazardous environments.

Application of hydraulic actuated gate valve

Hydraulic operated gate valve can be used as:

Emergency stop valve

High Integrity Protection System

High Integrity Pressure Protection System

Shut off valve

Surface safety valve

In the following applications:

Oil Wells - Conventional

Oil Wells - Gas Storage

Oil Well - High Pressure

Oil Wells - High Temperature

Wells - Water Treatment

Assembly line

Manifold

Sled

Design of hydraulic actuated gate valve

The actuator opens and closes hydraulically when hydraulic pressure is released. The modular design allows the actuator to be replaced independently of the gate valve and bonnet assembly for easy repair or replacement.

Main features of hydraulic operated gate valve:

1. The structure is simple, compact and small in size.

2. The transmission is stable and reliable, with buffering and no impact.

3. Different hydraulic oil can be used according to needs, and it can work in the temperature range of -45℃～+120℃. Can be explosion-proof.

4. A large output torque can be obtained, suitable for any specification.

5. The output torque can be adjusted by the constant pressure relief valve, including the adjustment of the opening and closing torque, which can be directly reflected by the hydraulic instrument.

6. Speed adjustment is convenient.

7. When the power is terminated suddenly in an accident, the accumulator can still be used for one or several power operations. This is of special significance for automatic emergency shut-off valves and inlet blow-off valves for long-distance pipelines.

Maintenance and inspection

To maintain the performance of the Hydraulic Actuated Gate Valve, regular maintenance and inspection are necessary. The valve should be cleaned periodically to remove any debris or corrosion that may cause the valve to malfunction. The hydraulic actuator must be checked regularly for any leaks, damaged seals, or worn-out parts. The valve should be lubricated periodically to ensure that it operates smoothly and efficiently.

In case of any malfunction, it is important to have a trained technician to diagnose and repair the valve. It is recommended to have a spare hydraulic actuator on hand to minimize downtime in case of a failure. The valve should also be tested periodically to ensure that it is functioning correctly and meets the required performance standards.
