A gate valve is a type of valve used to control the flow of fluids or gases in a pipeline. It is designed with a gate-like disc that slides across the pipeline to either open or close the valve. The disc is usually wedge-shaped, and it fits tightly into the pipeline, preventing any fluid or gas from flowing through the valve when it is closed.Gate valves are commonly used in the oil and gas industry, particularly in high-pressure applications where tight shutoff is required. They are also used in other industries such as water treatment, chemical processing, and power generation.The advantages of gate valves are their ability to provide tight shutoff, low pressure drop, and easy operation. They are also less prone to damage from the high pressure and harsh working conditions typically found in the oil and gas industry.Supcon offers a range of gate valves designed for various applications in the oil and gas industry. Our gate valves are built to withstand the toughest working conditions while providing reliable operation and long-lasting performance.

1. Full bore: Gate valves offer a full bore or unobstructed passageway, which allows for higher flow rates of fluid or gas with minimal pressure drop.
2. Low friction: The gate valve's streamlined design and low friction seals (such as metal-to-metal or resilient materials) offer low torque operation and reduced wear and tear.
3. Versatility: Gate valves are suitable for a variety of applications and come in a range of sizes and materials, including cast iron, bronze, carbon steel, stainless steel, and exotic alloys.
4. Easy maintenance: Gate valves have a simple design with few moving parts, making them easy to maintain and repair.
5. Tight shut-off: When the gate valve is fully closed, the gate forms a tight seal against the valve body, preventing any fluid or gas from passing through.
6. Durability: Gate valves are built to last and can withstand high pressures, temperatures, and abrasive fluids or gases.

1. Body: The main outer part of the valve that contains the other internal components.
2. Bonnet: The part that covers the top of the valve body and allows access for maintenance and repair.
3. Stem: The part that connects the gate to the handle or actuator that operates the valve.
4. Gate: A flat or wedge-shaped disk that slides across the pipeline to control the flow of fluids and gases.
5. Seats: The surfaces that the gate presses against when the valve is closed, creating a tight seal to prevent leakage.
6. Packing: A material that surrounds the stem and prevents fluid or gas from leaking out of the valve.
7. Gland: The part that compresses the packing material around the stem to provide a tight seal.
8. Handle or Actuator: The part of the valve that is used to operate the valve by turning the stem and moving the gate.These are the main parts of a gate valve. However, depending on the design and purpose of the valve, there may be additional components such as fasteners, gaskets, and more.
Gate valves work by raising or lowering a metal gate or barrier within the valve body to control the flow of fluids or gases through a pipeline. When the valve is fully open, the gate is fully retracted into the valve body, allowing maximum flow. When the valve is fully closed, the gate is fully extended across the pipeline, blocking the flow completely.Gate valves typically have a threaded stem connected to the top of the gate which extends through the top of the valve body and is connected to a handle or gear mechanism. When the handle is turned, the stem rotates and the gate moves up or down, opening or closing the pathway for the fluid or gas.Gate valves are used in applications where full open or full close flow is required, and are typically not used for regulating flow. They are commonly used in fluid control systems in industries such as oil and gas, chemical processing, and water treatment.
Easy maintenance
Maintenance and cleaning is made easier by the presence of bolts, nuts and screws. As a result, it makes removal from the pipeline easier.
Available in larger sizes
3" diameter valves are available in the market. Since most customers come from industrial applications, larger sizes are almost always used.
Suitable for thicker media
This valve is more flexible because its gate movement can be up or down, there are no obstacles in the fluid or gas flow, thus ensuring less friction.
Cost-effective
It lasts longer. When the valve is in normal use, replacement is less likely. In addition, as mentioned above, the bolts make inspection and maintenance easier.
Pinch valves use a flexible rubber or plastic tube that is pinched closed to regulate fluid flow.
