Plug Valve Supplier in Dubai

UAE Valves is known as a trusted Plug Valve Supplier in Dubai. A plug valve is an industrial valve designed to control the flow of fluids in a pipeline. It features a cylindrical or tapered plug with a through-hole, known as the port, which can be rotated within the valve body to allow or block the flow of fluid. Plug valves are widely used in industries such as oil and gas, petrochemical, water treatment, and power generation due to their simple design and reliable performance.

How Plug Valves Work?

In the open position, the plug aligns with the ports in the valve body, allowing fluid to flow through with minimal obstruction. The rotation of the plug, controlled by the stem and actuator, stops the flow by blocking the ports completely. By turning the stem connected to the plug, the valve can also be positioned partially open or closed to regulate fluid flow. The degree of opening or closing is adjusted by rotating the plug using the actuator.

Design:

The appearance of a plug valve varies based on its size, design, and construction materials. Common features include a cylindrical or tapered body with inlet and outlet ports, a stem extending from the top, and an actuator (manual lever, gear, or motor) attached to the stem. Materials used in construction depend on the type of fluid and environmental conditions, ranging from carbon steel to stainless steel and other alloys. Plug valves range from small sizes suitable for residential applications to large industrial valves used in heavy-duty processes.

Parts of a Plug Valve:

Body: The main structure that houses internal components and connects to the pipeline.
Plug: The cylindrical or tapered element with a through-hole that controls flow.
Ports: Inlet and outlet passages in the valve body.
Stem: Connects the plug to the actuator and transmits motion.
Actuator: Controls the rotation of the plug (manual lever, gear, or motor).
Bonnet: Covers the stem and provides access for maintenance.
Packing: Seals around the stem to prevent leakage.
Gland: Holds the packing in place.
Backseat: Provides a secondary seal when the valve is fully open.
Body Bolts and Nuts: Fasten the body components together.

Plug Valve vs. Ball Valve:

Design and Operation: A plug valve uses a cylindrical or tapered plug with passages to regulate fluid flow. The plug rotates within the valve body to allow or block flow. Ball valves have a spherical closing part (the ball) with a hole through its center. When opened, the ball's hole aligns with the flow path; rotating the ball by 90 degrees closes the valve.

Applications: Plug valves are known for their simple design, minimal leakage, and high-pressure handling, suitable for frequent operation or throttling. Ball valves offer quick and reliable shut-off, minimal pressure drop, and high flow rates, ideal for tight shut-off applications like gas or liquid pipelines.

Performance: Plug valves may suffer from wear and erosion in abrasive fluid applications, while ball valves may be more susceptible to damage from contaminants or particulate matter. Ball valves may not perform as well in throttling applications due to increased wear on sealing surfaces.
