Gate Valves
Gate valves are versatile flow control devices designed for on-off service in piping systems, suitable for both above-ground and underground installations. Their robust construction ensures reliable performance in various applications.
Available in cast and forged steel, gate valves are critical in industries like oil and gas, water treatment, and power generation, offering durability and cost-effective solutions, especially for underground systems where replacement costs are high.
Gate valves operate by raising or lowering a gate to control fluid flow, providing minimal pressure drop when fully open and a tight seal when closed. Their design makes them ideal for applications requiring full flow or complete shut-off, but they are not suited for throttling. Cast steel gate valves are used in larger, high-pressure systems, while forged steel variants are preferred for smaller, high-integrity applications. Selecting the right valve type is crucial, particularly for underground installations, to minimize maintenance and replacement costs.
Gate valves are manufactured to meet rigorous industry standards, ensuring performance and compatibility in various systems.
