Gate Valve H3002

The gate valve is used primarily for on-off, nonthrottling applications. When fully opened, the gate valve creates minimal obstruction to the flow. With less obstruction to the commodity’s rate of flow through the valve’s body, there is less turbulence, resulting in minimal drop in commodity pressure. Gate valves control the commodity flowing through the pipe with a flat, vertical wedge, or gate, that slides up or down as the valve’s handwheel is turned.

Key Components of a Gate Valve:
Body: brass
Gate (or Wedge): brass
Stem: brass
Seat: NBR
Bonnet: brass
Handwheel: steel

Size: 1/2″, 3/4″,1″, 1-1/4″, 1-1/2″, 2″

How a Gate Valve Works:
When the gate valve is open, the gate is fully raised, allowing fluid to flow freely through the valve.
When the gate valve is closed, the gate is lowered, sealing against the seats and stopping the flow of fluid.
The movement of the gate is controlled by turning the handwheel (or actuator), which rotates the stem and moves the gate vertically.

Applications of Gate Valves:
Water Supply Systems: Gate valves are commonly used to control the flow of water in municipal water supply systems, as well as in large plumbing systems.
Oil and Gas Pipelines: They are frequently used in the oil and gas industries for regulating the flow of crude oil, natural gas, and other petrochemical fluids.
Sewage Systems: Gate valves are used in wastewater treatment plants to control the flow of sewage and effluents.
HVAC Systems: In large-scale heating, ventilation, and air conditioning systems, gate valves are often used for controlling the flow of water or other fluids in large pipes.
Industrial Processes: Gate valves are commonly found in chemical, power, and manufacturing plants to control the flow of various liquids and gases.

Advantages of Gate Valves:
Minimal Flow Resistance: When fully open, gate valves provide a wide, unobstructed passage for fluid, which results in minimal pressure drop and fluid resistance.
Reliable Shutoff: Gate valves are very effective at providing a full shut-off when closed, making them ideal for on/off control in large pipelines.
Durability: They are robust and can handle high pressures and temperatures, which makes them suitable for heavy-duty applications in industries like oil and gas, water treatment, and manufacturing.
Long Service Life: Gate valves are known for their long lifespan, especially when properly maintained, because there is no rubbing or wear on the sealing surfaces when the valve is open.
