Product Description


what is the Grooved End Resilient Wedge OS &Y Gate valve ?what is the Standard of gate valves ?

Grooved End Resilient Wedge OS&Y Gate Valves are a special type of gate valve designed with grooved ends that allow for easy installation and connection to pipes using a grooved coupling system. The “OS&Y” designation indicates that it features an external screw and yoke design that provides clear visibility of the valve’s position and protects the stem threads from fluid.

The “Resilient Wedge” part of the name refers to the type of gate used in the valve. The elastic wedge gate is designed to deform slightly, ensuring a tight seal on the valve seat even in the presence of foreign particles or slight misalignment.

Gate valves are standardized by multiple organizations and follow industry standards to ensure compatibility and quality. The most common standards for gate valves include:

API (American Petroleum Institute) standards: API has several standards related to gate valves, such as steel gate valve API 600, compact steel gate valve API 602, corrosion-resistant, bolted bonnet gate valve API 603.

ANSI (American National Standards Institute) Standards: ANSI provides standards for industrial valves, including gate valves. ANSI B16.34 is a widely used standard that covers gate valve dimensions, pressure-temperature ratings, materials, and testing requirements.

AWWA (American Water Works Association) Standards: AWWA sets standards specifically for water industry applications. AWWA C509 and AWWA C515 cover resilient wedge gate valves used in water service.

ISO (International Organization for Standardization) Standards: ISO has standards for industrial valves, ISO 10434 and ISO 15761 are examples that cover gate valves for the oil and gas industry.
