However, its susceptibility to thermal locking and lack of self-alignment mean it is not suitable for high-temperature cycling services or applications where seat wear or pipe misalignment is a concern. For those conditions, a flexible wedge gate valve is often the preferred alternative. - [Flexible Wedge Gate Valve Design and Benefits](https://afbvalve.com/flexible-wedge-gate-valve-design-and-benefits/) - A Flexible Wedge Gate Valve is a type of gate valve where the disc (the "gate" or "wedge") is designed to be flexible. Unlike a solid, one-piece wedge, it has a cut or groove around its perimeter, creating a flexible region that allows the two halves of the disc to flex slightly independently. This design is a clever engineering solution to overcome a key challenge faced by solid wedge gate valves: thermal binding. - [Wedge Gate Valve Overview and Applications](https://afbvalve.com/wedge-gate-valve-overview-and-applications/) - A Wedge Gate Valve is a type of valve that uses a gate-shaped disc (the wedge) to stop or start the flow of fluid. It is one of the most common and oldest types of valves used in industrial piping systems. The "wedge" design is key—it is not a flat disc but is slightly angled, which helps to create a tight, sealing force against two inclined seats when the valve is closed. - [NRS Gate Valve Design and Applications Overview](https://afbvalve.com/327-2/) - This is a key design feature that distinguishes it from other types of gate valves, specifically the OS&Y (Outside Stem & Yoke) valve, which has a rising stem. - [OS&Y Gate Valve Overview and Features](https://afbvalve.com/osy-gate-valve/) - What is an OS&Y Gate Valve? An OS&Y Gate Valve (Outside Stem & Yoke) is a type of linear motion valve used primarily for on/off service, not for flow regulation. Its most distinguishing feature is a threaded stem that is visually exposed, which moves in and out of a handwheel as the valve is operated. The "Yoke" is a housing that supports the stem and provides a path for the stem to travel. The "Outside Stem" is the key visual indicator. - [Non-Rising Stem Gate Valve Overview](https://afbvalve.com/non-rising-stem-gate-valve-overview/) - What is a Non-Rising Stem Gate Valve? A Non-Rising Stem - [Rising Stem Gate Valve Overview and Features](https://afbvalve.com/rising-stem-gate-valve-overview-and-features/) - What is a Rising Stem Gate Valve? A Rising Stem Gate Valve is a type of linear motion valve used primarily for on/off control of fluid flow. Its most distinctive visual feature is that the handwheel (or actuator) and the stem rise together as the valve is opened. The "gate" in the valve is a solid disc or wedge that moves perpendicularly to the flow path. When the handwheel is turned, the stem threads into the yoke or bonnet, causing the stem to move upwards, which lifts the gate away from the seat and allows flow. Conversely, turning the handwheel in the opposite direction lowers the stem and gate, shutting off the flow. - [Bronze Gate Valve Overview and Applications](https://afbvalve.com/bronze-gate-valve-overview-and-applications/) - A bronze gate valve is a type of linear motion valve used primarily to start or stop the flow of a fluid (water, oil, gas, steam). It is not designed for flow regulation. The name comes from its disc (the "gate"), which is raised or lowered into the path of the flow via a handwheel and threaded stem. The body of the valve is made from bronze, an alloy primarily of copper and tin, often with small amounts of other elements like phosphorus or zinc. This material choice is key to its properties. - [Cast Iron Gate Valve Overview and Specifications](https://afbvalve.com/cast-iron-gate-valve-overview-and-specifications/) - A cast iron gate valve is a type of linear motion valve used primarily to start or stop fluid flow.
