These soft-seated butterfly valves are designed for a variety of general applications in the control of water, air, oil, gases and corrosive media. Examples of applications where these valves can be used are irrigation, cooling water and fire protection systems. They are equally effective for on-off, throttling or isolation service requirements. Lug style valves are designed for dead-end service to the full pressure rating of the valve. Model 88 butterfly valve is especially well suited for higher velocity service and vacuum service.
