Design Features:

• Gate Design: The valve features a wedge-shaped gate that moves perpendicular to the flow of the fluid. This design ensures a tight seal when the valve is closed, preventing leakage.

• Stem: The stem is typically made of stainless steel or another corrosion-resistant material. It connects the handwheel to the gate and is responsible for moving the gate up and down.

• Sealing: The valve is equipped with resilient seats that provide a tight seal against the gate. This ensures minimal leakage and long service life.

• Bonnet: The bonnet is bolted to the valve body and houses the stem and packing. It is designed to withstand the pressure and temperature conditions of the system.

Operation:
The valve is operated manually. For instance, turning the handwheel rotates the stem, which moves the gate up or down to open or close the valve. The manual operation allows for precise control of the flow.

Applications:
Manual cast steel gate valves are used in a wide range of applications, including:

• Oil and gas pipelines

• Water treatment plants

• Power generation facilities

• Chemical processing plants

Advantages:

• Durability: The cast steel construction ensures long-term durability and resistance to wear and tear.

• Reliability: The simple design and robust materials make the valve highly reliable.

• Ease of Maintenance: The valve is easy to maintain, with replaceable seats and packing.

• Versatility: Suitable for a wide range of fluids, including water, oil, gas, and steam.
