Asahi Type 57,56 & 75 Metal Gear Operator

Description

The name of this valve comes from the wing-like action of the flow-controlling disc, which operates at right angles to the flow. The disc has about the same diameter as the connecting pipe, and the flow is straight through, with a low pressure drop. Maintenance is easy due to the small number of moving parts. The butterfly valve can be used either as an on/off or modulating type of valve. The Type 75 Butterfly Valve is only offered in 18" to 24" sizes. These valves may be operated manually, electrically, or pneumatically.
