Engineered for maintenance flexibility and reliability
Type-57IL butterfly valves permit one side flange removal while maintaining full line pressure on the opposite side. Perfect for applications where periodic maintenance or equipment isolation is required without system shutdown.
Over-molded 316 stainless steel factory lugs allow bidirectional installation and superior strength.
316 stainless steel stem with full disc engagement is completely isolated from the media for extended life.
Only solid and abrasion-resistant plastic disc and elastomeric liner contact the media.
Offers increased Cv, ultimate sealing performance, and extended high cycle life.
Molded body stops and seat stress relief area prevent seat over-tightening damage.
ISO bolt circle on top flange requires no body or stem modifications for accessories.
Standard model with PVC body and PP disc provides excellent chemical resistance and elevated temperature capabilities.
Polypropylene stem retainer prevents accidental stem removal during operation.
Provides moderate flow control suitable for both on/off and modulating service applications.
Good tolerance to suspended solids, ideal for water treatment applications.
Plasgear™ gear operators standard for 3" to 12" valves for smooth operation.
