Application Scenarios of Wafer Type Ball Valves

Application Scenarios of Wafer Type Ball Valves

A wafer type ball valve is a compact, lightweight design that is installed between two pipeline flanges, secured by bolts. It’s commonly used where space and weight are limited.

1. Pipelines with Space Constraints

• Reason: No extended flange ends; short face-to-face dimension and compact size.

• Examples: Ship piping, building mechanical rooms, inside equipment skids.

2. Weight-Sensitive Installations

• Reason: Lighter than full-flange ball valves due to reduced material.

• Examples: Offshore platforms, mobile equipment, aerospace and vehicle fluid systems.

3. Medium- to Low-Pressure Fluid Control

• Typical Pressure Ratings: PN10, PN16, PN25 (some special designs can handle higher).

• Suitable Media:

• Water, oil, gas

• Corrosive chemicals (with PTFE, PFA lining or special alloys)

• Steam (with high-temperature seat materials)

4. Systems Requiring Quick Installation and Removal

• Reason: Can be replaced by simply loosening the flange bolts; minimal pipe movement needed.

• Examples: Industrial cooling water loops, pre- and post-filter sections, chemical reactor inlet/outlet.

5. Cost-Effective Solutions

• Reason: Simple design, lower manufacturing and shipping costs.

• Examples: Municipal water supply, HVAC systems, industrial chilled water networks.

6. Alternative to Butterfly Valves

• Used when better sealing is needed but space is still limited.

• Examples: Food and beverage processing, pharmaceutical purified water lines, fine chemical production.

✅ Summary:
Wafer type ball valves are ideal for medium- to low-pressure, weight-sensitive, space-limited, and quick-maintenance applications—such as building HVAC, ship systems, and chemical process loops. For high-pressure, large-diameter, or heavy-duty cycles, full-flange ball valves are usually preferred.
