Butterfly Valve Replacement Stands Up to Corrosion
Asahi/America has expanded its line of
butterfly valves to include the Type
57LIS, an industrial quality thermoplastic
valve that directly replaces metallic
butterfly valves, without modification to
the existing piping system, in applications
where metal valves constantly corrode.
The face-to-face dimensions of the Type 57LIS (the distance between the
two existing flanges), are the same as
those of the metal valves that the Type
57LIS replaces. It is available in 3-in.
to 8-in. sizes in lever style or with
Asahi’s Plasgear gear operator, the
industry’s first all-plastic housing
design. Standard models are supplied
as wafer-style for installation between
two flanges or factory equipped with
316 stainless steel lugs for end-of-line
applications. The Type 57LIS features
an ISO 5211 top flange mounting pattern
and molded padlock provision for
lever handle models. The valve can be
electrically or pneumatically actuated
using Asahi/America actuators. The
Type 57LIS are identical to those of
Asahi/America’s Type 57 and Type 57L
butterfly valves..
