Product Description

An ANSI cast steel gate valve is a type of gate valve constructed using cast steel materials in accordance with ANSI (American National Standards Institute) standards. These valves typically feature a solid cast steel body with a gate or wedge-shaped disc that moves vertically to control the flow of fluid through the valve.

Key features of an ANSI cast steel gate valve may include:

Robust Construction: Cast steel offers high strength and durability, making the valve suitable for high-pressure and high-temperature applications.
Tight Sealing: When fully closed, the gate provides a tight seal, minimizing leakage and ensuring reliable shut-off.
Bolted Bonnet: Many ANSI cast steel gate valves have a bolted bonnet design, allowing for easy access to internal components for maintenance or repair.
API Trim: Some valves may feature API (American Petroleum Institute) trim designs, providing enhanced performance and durability in demanding environments.
Rising Stem: ANSI gate valves often have a rising stem design, where the stem rises and lowers as the gate opens and closes, providing visual indication of the valve's position.
Flanged Ends: The valve may have flanged ends for easy installation and connection to piping systems.

Overall, ANSI cast steel gate valves are reliable, durable, and suitable for a wide range of industrial applications where tight shut-off and efficient flow control are required.


Positive Sealing: They provide tight shut-off, minimizing leakage when closed, which is crucial for applications requiring precise flow control.
Bi-Directional Flow: Gate valves can regulate flow in both directions, making them versatile for various piping systems.
Low Pressure Drop: When fully open, gate valves create minimal obstruction to flow, resulting in lower pressure drop across the valve compared to other types.
Durability: Constructed with robust materials, ANSI gate valves are designed for long-term use in demanding environments, offering excellent resistance to wear and corrosion.
Versatility: They are suitable for a wide range of fluids and temperatures, making them suitable for diverse industrial applications.
Ease of Maintenance: ANSI gate valves are relatively simple in design, facilitating easier maintenance and repair procedures, which helps reduce downtime.
Straight-Through Flow: When fully open, gate valves provide a straight-through flow path, minimizing turbulence and pressure loss.



A stainless steel gate valve operates similarly to other valves. To open the valve, turn the handwheel, which moves the gate up or down on the stem via the threads. A stainless steel gate valve requires more than one 360° turn to open or close the valve fully. When the stainless steel gate is lifted, it opens the inlet to the outlet allowing an unobstructed passageway for the media to flow. When the stainless steel gate is lowered, it closes and blocks the media flow.






Applications of Stainless Steel Gate Valves

Because of its resilience, a stainless steel gate valve is used in an array of industrial applications. These include:

Oil and gas industry;
Chemical and pharmaceuticals;
Marine;
Water and wastewater treatment;
Manufacturing industries.
