Wafer Butterfly Valves

What Are Wafer Butterfly Valves?
A wafer butterfly valve is installed between two matching pipeline flanges, with the valve body sandwiched and held in place by the flange bolts. This design provides a compact, lightweight and cost-effective solution for shut-off and flow control in industrial pipeline systems. The wafer body eliminates the need for separate flange connections on the valve itself, saving installation space and reducing weight compared with lug or flanged butterfly valve designs.
Honiks is a factory-backed industrial valve supplier in China with access to qualified partner factories for wafer butterfly valve production. See HN107 Wafer Butterfly Valve for catalog reference data covering DN50-DN600, PN10/PN16 with ANSI Class 150 dimensional reference and ISO 5211 operator connection.

Frequently Asked Questions
What applications are wafer butterfly valves suitable for?
Wafer butterfly valves are commonly used in water treatment, building services, HVAC water circuits, cooling water, circulation water and general industrial water pipelines where compact, lightweight installation is preferred.
Can wafer butterfly valves be supplied with an actuator?
Yes. The ISO 5211 operator mounting reference allows handle, worm gear and electric actuator configurations depending on valve size and project requirements.
