Grooved Swing Check Valve
Product Features and Applications
Structural Features
Swing design
In a swing check valve, the valve disc is connected by a hinge. When the media flows, the disc is pushed open, allowing the media to pass through. When the media flows backward, the disc automatically closes to prevent backflow
Grooved connection
The use of a grooved connection facilitates quick attachment and removal from the piping system without the need for complex tools and operations, significantly reducing installation time and costs.
Unidirectional flow
The valve is designed for unidirectional flow. When the media flows in the correct direction, the valve disc opens; when the media attempts to flow backward, the disc immediately closes to prevent backflow.
Strong sealing
The valve is typically equipped with abrasion-resistant sealing materials, such as rubber or metal sealing rings, to ensure stable sealing performance over long-term use.
Performance Features
Preventing backflow of media
When the media flows in the forward direction within the pipeline, the valve disc opens. When the media flows in the reverse direction, the disc automatically closes to prevent backflow and protect the system equipment.
Simple structure
The swing check valve has a simple structure, consisting mainly of the valve body, valve disc, and valve cover. The design is straightforward, making it easy to manufacture.
Easy to install
It can be installed either horizontally or vertically. The grooved connection method makes installation and removal more convenient and quick, without the need for complex tools and operations. It is suitable for situations with limited space and where frequent disassembly is required.
Low pressure loss
The smooth flow path design results in minimal pressure loss during media flow, ensuring overall system efficiency.
Corrosion resistance
Different materials can be selected, such as cast iron, ductile iron, and stainless steel, to meet the requirements of various media and operating environments, providing excellent corrosion resistance.
The device is highly reliable
“The valve disc and valve seat sealing surfaces are precisely machined, providing excellent sealing performance and a long service life
Application Fields
water treatment system
Widely used in water treatment systems such as municipal water treatment, wastewater treatment, and seawater desalination, to prevent medium backflow and protect pumps and piping systems.
HVAC (Heating, Ventilation, and Air Conditioning) system
In HVAC systems, the silent check valve is used to prevent backflow of chilled or hot water and to reduce operational noise in the system.”
fire protection system
The silent check valve is used in fire protection pipelines to prevent backflow of fire suppression agents and to avoid generating noise that could affect the surrounding environment.
industrial pipelines
Used in industrial pipeline systems such as those in the petrochemical, pharmaceutical, and food processing industries to ensure unidirectional flow of the medium and reduce operational noise
