What are some common types of Ductile iron Valve?

Here are some common types of Ductile iron Valve:

Gate Valves

Linear motion opens and closes a wedge-shaped disc to control flow. Used for on/off applications in pipelines.

Contain a movable disc that seals against a seat in the body. Suitable for regulation where partial flow is needed.

Round ball within the body pivots to open/close the path. Good for quick on/off in demanding services due to tight shut-off.

A disc mounted on the stem rotates perpendicular to flow. Compact design good for large pipe sizes and throttling.

Allows flow in one direction only using a swinging or tilting disc or clapper. Prevents backflow.

Cylindrical part lifted vertically to open cylindrical bore. Durable option for severe corrosive and high-pressure services.

Maintain downstream pressure regardless of flow or upstream pressure fluctuations.

Open if preset pressure limit is exceeded to protect lines and equipment from overpressure.

Ductile iron offers benefits like strength, corrosion resistance and damping that make it suitable for many demanding valve applications.
