CS Gate Valves

When sourcing CS Gate Valves for industrial pipeline systems, Hanno Valve offers a reliable solution that combines durability with performance. The internal medium channel of Hanno Valve CS Gate Valves is straight through, meaning the flow direction remains unchanged when the medium passes through. This design significantly reduces fluid resistance, lowers energy consumption, and improves overall system efficiency.

Product Features & Technical Advantages

Durable Carbon Steel Construction

Unlike standard gate valves, Hanno Valve CS Gate Valves are manufactured from high-strength carbon steel, with the opening and closing components designed as gate valves. The movement direction of the gate is perpendicular to the fluid flow, allowing only fully open or fully closed positions—no adjustment or throttling function, ensuring reliable sealing.

Precision Sealing Surfaces

Each CS Gate Valve features two sealing surfaces formed into a wedge shape. The wedge angle varies according to valve parameters. The gate can be made as a rigid integral piece or as an elastic gate that allows slight deformation. This elastic design improves processability and compensates for minor deviations in sealing surface angle during manufacturing.

Precision Casting for Reliable Sealing

The carbon steel valve body of Hanno Valve CS Gate Valves is precision cast. The precise geometric dimensions ensure excellent sealing performance without requiring any finishing work inside the valve body. This not only enhances quality but also shortens delivery time.
