Wedge gate valves made of steel are a type of industrial fitting used to cut off the flow of fluids within pipelines. These valves are known for their high resistance to pressure, temperature, and corrosion, making them suitable for various industries such as energy, heating, petrochemicals, gas, metallurgy, and mining.
The principle behind the operation of a steel wedge gate valve involves the linear movement of a wedge that either closes or opens the flow of the medium. The wedge is connected to a rising stem that moves upward or downward through manual, electric, or pneumatic actuation. The sealing of the wedge occurs through metal-to-metal contact with seat rings placed within the valve body. The valve body can be made of carbon steel, cast carbon steel, or alloy steel, depending on technical requirements and the working environment.
Advantages and disadvantages of steel wedge gate valves.
- High resistance to pressure, temperature, and corrosion — by utilizing steel for the valve body and wedge, along with metal sealing, these valves withstand high pressures and temperatures.
- Good sealing capability — owing to the wedge shape and seat rings, these valves ensure good sealing both when fully open and fully closed, effectively stopping the flow of the medium.
- Ease of operation and maintenance — due to the simplicity of the design and the ability to dismantle the wedge and stem without removing the valve from the pipeline, these valves are easy to operate and maintain.
