What Is A Hydraulic Butterfly Valve? Benefit And Application

Industrial operations control fluid flow through opening/closing of butterfly valves. A hydraulic butterfly valve is a form of an automatic valve that generates opening/closing movement through hydraulic pressure. The valve functions through a rotatory motion, converting hydraulic pressure into mechanical energy. Other actuators include electrical and pneumatic.

Functionality Of A Butterfly Valve

The regulation of flow in larger pipes is carried out through butterfly valves. Butterfly valves can either be handled manually or with gearboxes, or by automatic actuators entirely e.g. electric, pneumatic, or hydraulic actuator butterfly valves. Various types and forms of butterfly valves exist, each playing a pivotal role in different industries.

The butterfly valve operates mainly through discs and rods in quarter-turn movements. The disc connects to a rod which rotates 90 degrees and parallel to the flow direction, allowing fluid to pass through the valve. It then closes when the rod rotates the disc by another quarter 90-degree turn that is perpendicular to the flow direction. Different disc closure types exist e.g. concentric or electric, along with the design of the ends of the valves.

Functionality of A Hydraulic Actuator Butterfly Valve

Actuators generally use motors, pumps, cylinders, and valves to produce motion. The butterfly valve hydraulic actuators are designed with few mechanical parts, with a 90-degree movement system. They have pressurized cylinders that allow mechanical energy to be formed using hydraulic pressure.

Also, hydraulic actuators can be single-acting and double-acting. Both types use different mechanisms to control fluid flow. While double-acting actuators use an in-built hydraulic pump to control motion, single-acting actuators open and close through fluid pressures and rotatory motion.

Pros Of Hydraulic Actuator Butterfly Valve

Hydraulic actuator butterfly valves provide many benefits:

They consist of oil-filled cylinders that allow for greater precision and high-accuracy actuation.
Hydraulic actuators have much greater torque which can be adjusted and is ideal for powerful machinery.
These valves provide continuous motion in case of a power failure and without an extra power source.
They have compact structures with smaller volumes and reliable transmission.

Butterfly Valve Hydraulic Actuator Application

Powering different industries, the butterfly valve hydraulic actuators are used in various initiatives. Their greater force exertion and torque make for excellent heavy-duty machinery and equipment, with up to 5000 psi. They offer significant accuracy and are commonly used in the following industries:

Manufacturers
Automotives
Oil and Gas Industry
Ship Components
Agriculture Industry
Defense Systems

FAQ

What Are Pros Of Hydraulic Actuator Butterfly Valve?

These valves have simple structures with small volumes and stable transmission. The speed can be conveniently adjusted, and they produce higher torques. Electricity shortages do not affect the hydraulic actuator butterfly valve even for several power operations afterwards.
How Does A Butterfly Valve Work?

Operating in quarter-degree turns, the disc in a butterfly valve is attached to a rod. When the disc rotates 90 degrees parallel to the flow, the fluid passes through. When it rotates another 90 degrees, the disc becomes perpendicular to the flow and closes.

Final Thoughts

Choosing which butterfly valve or actuator to use requires in-depth research and further insight into a butterfly valve factory. The hydraulic actuator butterfly valve provides many benefits in the long run. Looking for butterfly valve manufacturers in China?
