The Double Flanged Short Type Butterfly Valve (Series F401) is a high-performance industrial flow control solution engineered for precision and durability. Designed in accordance with ISO 5752 basic series 13 and DIN 3202 part 1 series F16, this valve features a specialized rubber liner spliced directly onto the body, significantly enhancing structural strength and ensuring a more reliable seal for the seat.
Engineered for versatility, the Series F401 is available in sizes ranging from 2" to 48", making it ideal for a wide array of piping systems. To maximize installation efficiency, an integrated O-ring is cast onto the seal surface, completely eliminating the need for external flange gaskets. Whether you require manual gear operators, handles, or advanced electric and pneumatic actuators, this valve delivers uncompromising performance across diverse industrial applications.
