Axial non-impact check valve

Product Overview

Axial non-shock check valves are designed to provide reliable backflow prevention in pipelines where high velocity or sudden backflow may occur. Unlike traditional swing check valves, the slow-closing feature ensures that the valve flap does not "slam" or close suddenly, thereby preventing water hammer and reducing mechanical wear. The valve is particularly suitable for high velocity applications and is ideal for use in industries such as water treatment, power generation, oil and gas, and chemical processing. It enhances durability, reliability and protection of downstream equipment, while ensuring smooth and controlled fluid flow in critical applications.

Product Features

Shock-free design: The valve's shock-free mechanism ensures smooth, progressive flap closure. This design prevents violent shocks from high velocity water flow, thus reducing the risk of water hammer and protecting downstream equipment.

Axial Flow Design: The axial flow design of this valve allows fluid to flow in the direction of the valve body, minimizing pressure loss and ensuring efficient system flow. This also reduces turbulence and stress on valve components.

Rapid Closing Mechanism: The valve utilizes a spring-assisted mechanism that quickly closes when backflow is detected, preventing backflow and protecting system integrity.

CORROSION AND ABRASION RESISTANCE: Constructed of durable materials such as stainless steel, carbon steel, and alloy steel, this valve is resistant to corrosion, abrasion, and erosion, providing long-lasting performance in harsh environments.

Compact and robust construction: Its compact design makes it ideal for installation in confined spaces without any compromise in performance. It is designed to handle the stresses and pressures associated with high velocity flow.

Product Advantages

Protection against water hammer: The anti-slam feature ensures that the valve flap closes slowly, significantly reducing the risk of water hammer. This not only prevents damage to pipes, but also minimizes system noise and vibration.

Extended system life: The gentle closing action minimizes mechanical stress on the valve and surrounding components, thus extending the life of the entire system.

Improved Flow Efficiency: The axial flow design ensures smooth fluid flow and minimizes pressure drop, thus improving system efficiency and reducing energy consumption.

Wide range of applications: Suitable for a variety of high-speed fluid flow applications such as power generation, water treatment, chemical processing, and oil and gas pipelines.

RELIABILITY AND SAFETY: The valve provides reliable unidirectional flow control, protecting downstream equipment from the negative effects of backflow.

Applicable working conditions

Axial non-impact check valves are ideal for industries and applications that require reliable backflow prevention and ensure smooth fluid flow, for example:

Water and Wastewater Treatment Plants: Prevent backflow and backpressure, ensure efficient system operation and protect downstream equipment.

Power Generation: Protects pumps, turbines and compressors from backflow and water strike, ensuring safe and efficient steam and water systems.

Oil and gas pipelines: Protect critical infrastructure (including pumps and compressors) from harmful backflow in high-pressure pipeline systems.

Chemical Processing: Suitable for handling a wide range of fluids in chemical plants, ensuring that hazardous materials do not flow back and cause contamination or damage.

Industrial Fluid Systems: Ideal for applications that require backflow prevention in high velocity, high pressure environments, such as HVAC systems, fire suppression systems, etc.
