Q:What connection does dual plate wafer type check valve have?

TVCCL dual plate check valve has a compact and versatile design, with its main connection type being the "wafer" style. Nevertheless, this design can be modified to suit various connection requirements. The following are the typical connection types for dual plate check valves:

1. Wafer Style:
This is the most common connection type for dual plate check valves. The valve is designed to fit between two pipeline flanges without any bolt holes of its own. The pipeline flanges provide the necessary bolt holes, and the valve is held in place by the tension of the bolts that are passed through the flanges.
It's a very compact design, making it suitable for tight spaces.

2. Lug Style:
Lug-style dual plate check valves possess lugs or ears encircling the valve body, which have bolt holes aligned in correspondence with those situated in the pipeline flanges.

3. Double Flanged Style:
Some dual plate check valves are equipped with flanges on both sides of the valve body. These flanges can be directly bolted to the pipeline flanges.
This type of design is less frequent than the wafer or lug styles but can be used in particular situations or larger pipeline systems.

Points to Consider:
The connection type chosen often depends on the specific application, installation requirements, and maintenance needs.
It is crucial to ensure that the selected connection type is compatible with the existing pipeline flanges and satisfies the system's pressure and flow
requirements.

In summary, although the wafer style serves as the prevailing connection type for dual plate check valves, other alternatives, such as lug style and double flanged style, exist to meet particular installation and application requirements.
