Wafer Butterfly Valve
Compact isolation between mating flanges
The wafer body sits between two mating flanges. Allow the disc to open without touching the pipe or nearby equipment, and select the seat for the fluid.
Final selection requires the complete product code and the service conditions.
UNDERSTAND THE APPLICATION
A solution for your application.
Application areas
Flow isolation in process lines with a suitable seat · In-line disc-based flow control
Selection considerations
Check flange fit, disc clearance and seat compatibility with the medium.
Specify the nominal line size and connection standard, together with the need for isolation, regulation or automation. Two valves of the same nominal size may differ in materials or connection dimensions.

Frequently asked questions
Which parts must be checked against the liquid?+
Check the disc (GGG40 / AISI 304 / AISI 316) and seat (EPDM / NBR / VITON) against fluid chemistry and operating temperature. Identical size does not make different material choices interchangeable.
Does the 16 bar rating apply at every temperature?+
16 bar and 120 °C are quoted as separate limits. Verify the design point for the selected size, seat and body.
What should I verify before specifying Truevalve Wafer Butterfly Valve?+
Evaluate pressure and temperature together. Verify the ratings that apply to the selected body, sealing materials and end connections in the model-specific technical document.
What should I include in my quotation request?+
Line size and connection standard; Fluid, operating pressure and temperature; Isolation or control duty and actuation method. For replacement equipment, also provide the nameplate and connection dimensions.
Where can I check the technical drawing and dimensions?+
Open the manufacturer PDF in the Technical Documents section. Match the relevant entry to the product type, nominal size and variant code. Not every option in a family catalogue belongs to the same product.
