Cast iron gate valves are a type of linear motion valve used to isolate or regulate flow in industrial piping systems. The name "gate valve" comes from the gate-like sliding wedge that controls fluid flow through the valve body.
The cast iron body and bonnet provide durability and pressure retention. When open, gate valves have an unrestricted, full-bore passageway. Closing the valve fully obstructs flow for isolation or maintenance. Gate valves are not suitable for throttling or frequent operation.
Common types of cast iron gate valves include solid wedge, flexible wedge, parallel slide, knife gate, and double disc designs. Sizes typically range from 2-48 inches or larger. End connections can be flanged or threaded.
Cast iron gate valves are often preferred for their strength, corrosion resistance, low maintenance, and tight sealing. They handle well in high temperature and pressure applications. Typical applications include steam, water, oil, gas, sewage, and more. Proper selection, installation, and maintenance are key to maximizing service life.
Cast iron gate valves offer reliable on/off flow control and isolation for industrial piping systems. Their sturdy construction makes them a long-lasting flow control solution.Shop our huge selection of top quality cast iron gate valves today.
