UAE Valves is the topmost Check Valve Supplier in Dubai.. A check 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. Check 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 Check 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.
Parts of Check 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.
Check Valve vs. Ball Valve
Design and Operation: A check 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 closure part (the ball) with a hole through its center. When open, the ball's hole aligns with the flow path; rotating the ball by 90 degrees closes the valve.
Applications: Check 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: Check 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.
