Cast Iron Gate Valves

Reliable Flow Control for Waterworks and Industrial Systems

Cast iron gate valves are a trusted choice in waterworks, plumbing and industrial piping systems where a reliable shut-off is required. Built from cast iron and designed with a sliding gate mechanism, these valves provide an effective way to stop or allow flow in large-diameter pipelines. Their sturdy construction makes them well-suited for low- to medium-pressure applications across municipal and industrial settings.

Design and Function

A cast iron gate valve operates by raising or lowering a gate inside the valve body. When open, the valve allows a straight, unobstructed path for liquid to pass through, minimizing pressure loss. When closed, the gate creates a solid barrier to stop flow completely. Options such as cast iron flanged gate valves make installation straightforward, while cast iron non-rising stem gate valves are preferred for underground or confined-space applications where vertical clearance is limited.

Applications of Cast Iron Gate Valves

Cast iron gate valves are widely used in:

• Water distribution systems for municipal and commercial networks

• Wastewater and sewage treatment facilities

• Fire protection and hydrant lines

• Irrigation systems and agricultural service lines

• General utility pipelines carrying non-corrosive fluids

These valves provide dependable performance in pipelines where complete shut-off is more important than throttling or frequent flow adjustments.

Advantages

• Strong body construction offering durability under pressure

• Low pressure drop when fully open

• Availability in a wide range of sizes for small to large pipelines

• Cost-effective solution compared to higher-alloy materials

• Flanged ends for secure connections in industrial networks
