The elastomer-seated sliding valve is designed to safely direct the flow of fluids. This type of valve is used to provide sealing on the pipeline through which the fluid passes. Especially with the elastomer-coated slide, it enables complete shut-off functionality. The slide inside the valve body is moved up and down to open or close the valve.

Elastomer material is also preferred in these valves to reduce friction within the valve. This helps minimize the risk of wear during long-term operation. Elastomer-seated sliding valves offer high sealing performance, making them ideal for critical installations where reliable leakage prevention is essential. As such, they provide excellent solutions for systems that require precise and efficient flow control in demanding environments.

How Does an Elastomer-Seated Sliding Valve Work?

The elastomer-seated sliding valve integrated into the system is moved up or down with the help of a shaft. When the shaft moves, the valve slide is lowered, completely closing the fluid passage. Conversely, when the slide is lifted, the valve opens, allowing the fluid to flow.

The elastomer coating inside the valve provides a high level of sealing between the slide and the body. This ensures reliable sealing even at low pressures. Additionally, the elastic nature of the internal coating helps absorb vibrations, which in turn extends the operational lifespan of the valve.

Where Are Gate Valves Used?

Sliding valves are widely used across many industries. They are primarily preferred in infrastructure projects for controlling drinking water pipelines. Additionally, they are used in wastewater treatment plants for the management of chemical liquids.

Sliding valves are commonly used in power plants, cooling systems, and heating lines. They are also reliably chosen for pipelines that transport acidic or basic liquids in industrial facilities. Additionally, they offer long-lasting performance in agricultural irrigation systems, providing a significant advantage in durability.

Why is an Elastomer-Seated Sliding Valve Preferred?

Sliding valves stand out for their quiet operation, long lifespan, and ease of maintenance. Due to the low friction they offer during fluid flow, they contribute to energy efficiency. Additionally, the flexibility of the elastomer material helps protect the system during sudden pressure changes, ensuring stable and safe operation.

The ability to be used with manual, electric, or pneumatic actuators provides great flexibility. In high-capacity systems, this helps reduce the risk of failure and decreases maintenance frequency. For this reason, sliding valves are frequently preferred in both public infrastructure projects and private facilities, offering reliable and efficient solutions in various applications.
