These soft-seated butterfly valves are designed for a variety of geneal applications in control of water,ail,oil,gased and corroosive mediua. They are equally effective for on-off, throtting, or isolation service requirements. Lug style valves are designed for dead-end service to the full pressure rating of the valve. Model 87 and 88 butterfly valves are especially well suited for higher velocity service and vacuum service.
