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.
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.
Packing
Standard export wooden case packaging
Application Scenarios
This valve finds extensive use in pipeline networks for industries ranging from water supply, sewage disposal and fire safety systems to petroleum refining, chemical manufacturing, power engineering and metallurgical operations. It demonstrates particularly strong compatibility with piping layouts where installation space is restricted.
Frequently Asked Questions
What is the structure and type of this check valve?
This is a wafer check valve featuring a double disc structure designed for single-directional sealing.
What manufacturing standard and workmanship does the valve follow?
The valve is manufactured in compliance with the BS5153 standard and is produced using precision investment casting workmanship.
What is the working temperature range and sealing performance of this valve?
