Challenger offers a complete line of Butterfly Valves in sizes 2” - 48” in both wafer and full lug configuration to service your H.V.A.C, pneumatic conveying, food & beverage, chemical and bulk handling applications. The close tolerance Double ‘D’ disc/stem connection in sizes 2” - 12” provides the superior strength of a through shaft design without the disadvantages associated with designs using disc screws and pins which tend to fail over time through abrasion, corrosion or fatigue. Our unique “Epsilon” seat design in sizes 2” - 12” is rated for 225 psi full dead end pressure with the downstream flange removed (lug body).

The Chemline redesigned hand lever no longer has external metal parts. The Type 57 has a redesigned valve "top flange" and shaft, now conforming to ISO for standardized actuator mounting*. These valves offer a large range of sizes and selection of body, disc and seat materials. This allows them into a wide range of on/off or throttling control applications.

Trueline has developed a line of high quality reliable butterfly valves. Easy maintenance and component interchange means lower installed cost and years of service life from our proven design. The butterfly vales are well suited to a host of today's industrial services.
