Gate valves are widely used to regulate the flow of fluids in various industrial and commercial applications. One type of gate valve you may encounter is the resilient wedge gate valve. This design is well-suited for applications that involve high pressures and temperatures, abrasion, and erosion. This post will discuss the different types of resilient wedge gate valves and their uses. By the end of this post, you’ll better understand the different gate valve options available.

Types of Resilient Wedge Gate Valve

Non-Rising Stem Resilient Wedge Gate Valve

The non-rising stem valve is one of the most common types of resilient wedge gate valve. This design is ideal for underground applications where access to the valve is limited. Non-rising stem valves require less space and are easier to install than other designs. The non-rising stem is connected to the gate by threaded connections. The valve is designed to produce a tight seal even at high pressures and temperatures. Non-rising stem valves are used in water distribution, sewage, and underground applications.

Rising Stem Resilient Wedge Gate Valve

Rising stem valves are commonly used in above-ground applications where access to the valve is not limited. The valve’s stem rises when the gate is lifted, indicating that the valve is open. The rising stem can be used to manually control the flow of fluid through the valve. The rising stem valve design is commonly used in the oil and gas industry and in chemical processing plants.

Double Disc Resilient Wedge Gate Valve

The design of the double disc resilient wedge gate valve is well-suited for larger piping systems. This design features two gates with a resilient seal, which provides a tight seal even at high pressures and temperatures. The double-disc design also reduces the torque required to operate the valve, making it easier to use. Double-disc valves are often used in water distribution, fire protection, and other large piping applications.

Parallel Resilient Wedge Gate Valve

Parallel resilient wedge gate valves are designed for use in applications that require frequent use. This design features a parallel gate that provides a tight seal even after extended use. Parallel gate valves are suited for water distribution systems, sewage systems, and other applications that require frequent valve operation.

Sluice Resilient Wedge Gate Valve

Sluice resilient wedge gate valves are suited for very high pressures and are commonly used in the oil and gas industry. This design features a heavy-duty resilient seal that can handle high temperatures and pressures without leaking. The sluice gate valve is often used in applications that require isolation of a specific section of the pipeline, such as during maintenance or repair.

Conclusion:

The resilient wedge gate valve is a popular choice for industrial and commercial applications because it provides a tight seal at high pressures and temperatures. By understanding the different types of resilient wedge gate valves and their uses, you can ensure that you select the appropriate valve for your application. Whether it’s a non-rising stem valve for an underground application, a rising stem valve for above-ground use, or a sluice valve for high-pressure applications, there is a resilient wedge gate valve design for every application.
