Product Description

Product Specifications

Valve Type Wafer check valve Structure Double disc
Standard BS5153 Workmanship Investment casting
Sealing Direction Single-directional Sealing Grade Zero leakage
Temperature -20°C < T < 120°C Operation Self-starting

Characteristics

This valve adopts a wafer-type mounting design, which allows it to be directly sandwiched between a pair of pipeline flanges without requiring additional extended installation space. In contrast to flange-connected check valves, this configuration substantially reduces the spatial footprint of the entire piping system, rendering it particularly suitable for narrow or constrained installation environments.
Wafer Check Valve Characteristics

Key Advantages

1
Easy Installation: Adopting a clip-on installation method, i.e. chip design, it can be easily installed between two pipeline flanges, saving space, reducing the overall weight of the system, and facilitating installation in narrow spaces.
2
Good Fluid Performance: The valve disc adopts a lightweight design and is equipped with low friction bearings, with low opening pressure, low fluid resistance, and smooth flow channels, which can reduce the energy consumption of power equipment such as pumps and compressors.
3
Excellent Sealing Performance: The double valve disc is precision machined, with a smooth sealing surface, and forms a double sealing barrier with an elastic valve seat. It can quickly close when the medium flows back, and has good sealing performance.

Frequently Asked Questions

What is a wafer check valve and how does it differ from a flanged check valve?
A wafer check valve is designed to be clamped directly between two pipeline flanges using bolts, eliminating the need for additional flanged ends on the valve itself. Compared to flanged check valves, the wafer type is significantly more compact, lighter, and requires less installation space.
What is the operating temperature range of this wafer check valve?
This valve is designed to operate within a temperature range of -20°C to 120°C (-4°F to 248°F), making it suitable for a wide variety of industrial fluid applications including water supply, chemical processing, and petroleum systems.
What standard does this valve comply with?
This wafer check valve is manufactured in compliance with BS5153, the British Standard specification for check valves. It ensures consistent quality, dimensional accuracy, and reliable performance in industrial pipeline systems.
How does the double disc design improve sealing performance?
The double disc design features two precision-machined valve discs with smooth sealing surfaces. Together with an elastic valve seat, they form a double sealing barrier that achieves zero leakage and prevents backflow rapidly.
In which industries is this wafer check valve commonly used?
This valve is widely applied in municipal water supply, sewage disposal, fire protection, petroleum refining, chemical manufacturing, power generation, and metallurgical operations, especially where installation space is limited.
How is this wafer check valve packaged for export?
The valve is packaged in standard export wooden cases, providing robust protection against impact, moisture, and environmental damage during international shipping and long-distance transportation.
