Wafer Butterfly Valve

A butterfly valve designed to fit between two pipe flanges without its own flange bolting - the pipe bolts pass around the outside of the valve body. Lowest cost and lightest style. Cannot be used at end-of-line (pipe must be flanged on both sides). Lug design is needed for end-of-line service.

What is a Wafer Butterfly Valve?

What is a Wafer Butterfly Valve used for?

Wafer Butterfly Valves are used in industrial piping systems for on-off isolation, flow control, or backflow prevention depending on the valve type. They are selected based on the process fluid, operating pressure and temperature, required shutoff class, and pipeline size. Vajra Industrial Solutions supplies Wafer Butterfly Valves certified to API 6D, ASME B16.34, and other applicable standards.

How do I select the right Wafer Butterfly Valve for my application?

Selecting the correct Wafer Butterfly Valve requires specifying: (1) nominal pipe size (NPS/DN), (2) pressure class per ASME B16.34, (3) body and trim material based on fluid compatibility and temperature, (4) end connections (flanged RF/RTJ, butt-weld, socket-weld, or threaded), (5) required certifications (API 6D, ISO 9001, fire-safe API 607).
