Advantages of the product

Reliable Backflow Prevention with Check Valve

Our check valves are engineered to provide reliable backflow prevention. The internal check mechanism automatically closes when the fluid flow reverses, preventing the backflow of fluids or gases. This is essential for protecting equipment, maintaining system integrity, and ensuring the proper flow direction in pipelines, such as in water supply systems and industrial processes.

Quick - Response Check Valve

Featuring a sensitive and fast - acting check mechanism, our check valves can respond rapidly to changes in flow direction. This quick - response capability ensures immediate backflow prevention, minimizing the risk of damage to connected equipment and maintaining the stability of the fluid system, especially in applications with fluctuating flow rates.

Swing check valves are critical components in fluid control systems, designed to allow flow in one direction while preventing backflow. At Guangzhou FOLS Valve Technology Co., Ltd, we specialize in manufacturing high-quality swing check valves that meet international standards. Our valves are engineered to operate effectively in diverse environments, from industrial applications to municipal water systems.The design of our swing check valves incorporates a disc that swings open with the flow of fluid and closes automatically when the flow reverses, preventing backflow and potential damage to the system. This mechanism is vital for maintaining system integrity and efficiency. Our valves are available in various sizes and materials to suit specific application needs, ensuring optimal performance.

With a focus on innovation and quality, our swing check valves undergo rigorous testing to ensure they can handle high pressures and temperatures. This commitment to quality has positioned us as a trusted supplier in the valve manufacturing industry, with a reputation for excellence built over 47 years.

Our team of experts is dedicated to providing exceptional customer service and technical support, helping you select the right swing check valve for your application. We understand the importance of reliability in fluid control, and we strive to exceed customer expectations with every product we deliver.

common problem

How do your check valves prevent backflow effectively?

Our check valves use internal mechanisms like swing discs, lift - type discs, or tilting discs. When fluid flows in the forward direction, the disc opens; when the flow reverses, the disc closes immediately, forming a tight seal against the valve seat to prevent backflow.

Are your check valves suitable for high - flow applications?

Yes, our check valves are available in various sizes and designs to handle high - flow applications. Their streamlined internal structures reduce resistance to flow, allowing for smooth passage of large volumes of fluids or gases while still ensuring reliable backflow prevention.

Can your check valves be installed in any orientation?

While some check valves can be installed in different orientations, it depends on the type. Swing check valves are typically installed horizontally, while lift check valves can be used in vertical or horizontal pipelines. We provide clear installation guidelines for each model to ensure proper operation.
