Type-57P butterfly valves are versatile quarter-turn valves with equal percentage flow characteristics, suitable for both on/off and modulating service. These valves offer moderate flow control and are well-suited for a wide range of fluid flow applications, with good tolerance to suspended solids. Featuring a 316SS stem with full disc engagement, a full seat design eliminating the need for gaskets, and seat overtightening prevention, these valves ensure reliable and leak-free operation. The lockout-tagout lever handle with molded padlock provision and visible position indicator with fine adjustment locking positions enhance safety and ease of use. With an ISO 5211 top flange, polypropylene stem retainer, and non-wetted stem and body design, these valves provide durability and isolation from the media. The Type-57P butterfly valves also come with a Plasgear operator, making them the ideal choice for efficient and dependable flow control.
