    K-LOK Figure 310/312 High Performance Butterfly Valve
    K-LOK High Performance Butterfly Valve. Sizes 2 thru 12-inch ANSI Class 150.
    • Uninterrupted gasket surfaces eliminate problems associated with seat retaining screws in the gasket surface and allows use of standard spiral wound gaskets.




    Keystone Figure 221/222 Resilient Seated Butterfly Valve
    Resilient Seated Butterfly Valve Sizes 2 thru 12-inch to 250 psi.
    • Molded in resilient seat provides bubble-tight shutoff to 250 psi.
    • Offered in two body styles: wafer and lug. The lugged body is drilled and tapped for isolation and removal of downstream piping at full rated pressure.


    Keystone Figure 990/920 Thin Disc Butterfly Valves
    Thin Disc Resilient Seated Butterfly Valves. Sizes 1 thru 20-inch to 150 psi.
    • One-piece, thin profile, 316 Stainless steel disc/stem provides minimum obstruction to flow, resulting in highest Cv, lowest pressure drops and best control characteristics. Also available with PTFE, NBR or EPDM molded disc.


    Keystone Figure AR1/AR2
    Resilient Seated Butterfly Valves. Sizes 2 thru 12-inch to 175 psi. Sizes 14 thru 36-inch to 150 psi.
    • Triple function resilient seat provides bi-directional drop-tight shutoff and totally isolates the valve body and stem from the line media.
    • Molded-in o-ring seat design serves as flange seals, totally eliminating the need for gaskets between the flanges and the valve.
