Characteristics
With a wafer-type structure, it can be directly clamped between two pipeline flanges, eliminating the need for extra installation clearance. Compared with flange-end check valves, it significantly minimizes the overall footprint of the piping system, making it ideal for space-restricted applications.
Advantages
1
Anti Impact, Shock Absorption and Noise Reduction
Partial clamp check valves are equipped with buffering mechanisms or damping devices, which can reduce the impact force when the valve disc is closed, weaken the influence of water hammer effect, reduce the noise and vibration during valve opening and closing, and protect the safe operation of pipelines and downstream equipment.
2
Low Maintenance Cost
The structure has a high degree of modularity, and vulnerable parts such as valve discs and seats can be quickly disassembled and replaced without the need to dismantle the valve as a whole; The inner wall of the flow channel is smooth and not easy to accumulate impurities, making daily cleaning and maintenance convenient and reducing downtime for maintenance.
3
Wide Material Adaptability
The valve body can be made of ductile iron, cast steel, stainless steel and other materials. The valve disc and seat can be matched with stainless steel, copper alloy or wear-resistant rubber according to the characteristics of the medium, which can adapt to various working conditions such as water, sewage, oil, acid and alkali media, and meet the anti-corrosion and wear-resistant needs of different industries.

Frequently Asked Questions
Q
What is a wafer check valve and how does it work?
A
A wafer check valve is a non-return valve with a wafer-type body that is clamped between two pipeline flanges. It uses a double disc mechanism that opens automatically when forward flow pressure overcomes the spring force, and closes instantly when flow stops or reverses, preventing backflow in the system.
Q
What is the operating temperature range for this wafer check valve?
A
This valve is designed to operate within a temperature range of -20°C to 120°C, making it suitable for a wide variety of industrial and commercial fluid systems.
Q
What materials are available for the valve body and internal components?
A
The valve body can be manufactured from ductile iron, cast steel, or stainless steel. Valve discs and seats can be matched with stainless steel, copper alloy, or wear-resistant rubber depending on the media and working conditions required.
Q
What industries and applications is this wafer check valve suitable for?
A
This valve is widely used across water supply, wastewater treatment, fire protection, petroleum, chemical processing, power generation, and metallurgy industries. Its compact wafer design makes it especially ideal for space-constrained pipeline installations.
Q
How does this valve help reduce water hammer effects?
A
The valve is equipped with buffering mechanisms or damping devices that reduce the impact force when the disc closes. This weakens the water hammer effect and minimizes noise and vibration during operation, protecting pipelines and downstream equipment from damage.
Q
Is the wafer check valve easy to maintain and service?
A
Yes. The modular design allows vulnerable parts such as valve discs and seats to be quickly disassembled and replaced without removing the entire valve from the pipeline. The smooth inner flow channel also resists impurity buildup, reducing the frequency and cost of routine maintenance.
