Aluminium Bronze Rising Stem Gate ValveC-Way Engineering Exports manufactures and supplies Rising Stem Gate Valves with Outside Screw and Yoke (OS&Y) construction for industrial piping, process plants, oil & gas, petrochemical, power generation, water, and utility applications.
A Rising Stem Gate Valve, commonly called an OS&Y Gate Valve, is designed to isolate flow in industrial piping systems. As the valve opens, the stem moves upward. As it closes, the stem moves back down. This visible stem movement gives operators a quick indication of valve position.
OS&Y stands for Outside Screw and Yoke. The stem and operating mechanism are located outside the valve body, making the assembly accessible for operation and inspection. This design is widely used where clear valve-position indication and dependable isolation are important.
C-Way supplies Rising Stem Gate Valves in carbon steel, cast steel, stainless steel, alloy steel, ductile iron, duplex, super duplex and other materials, depending on the application.
Valve configurations can include solid wedge, flexible wedge, split wedge and parallel slide designs, with bolted bonnet or pressure-seal construction where required.
Typical applications include oil and gas pipelines, refineries, petrochemical plants, power plants, water treatment facilities, steam systems, process piping and industrial utility systems.
C-Way Rising Stem Gate Valves can be manufactured and supplied to applicable API, ASME, ISO, EN, DIN, BS and JIS standards, depending on valve design, pressure class, material, end connection, service conditions and project requirements.
