Deyi Sanitary Stainless Steel Butterfly Valves

Butterfly Valves
DEYI butterfly valves are reliable shut-off valves that can be operated manually or pneumatically. These valves are known for their robust construction, making them ideal for a wide range of applications. Their compact design allows for easy installation and maintenance, offering flexibility in various industrial settings.


Key Advantages
Smooth flow passages ensure efficient operation, while special seals allow for thorough cleaning. The unique metallic stop prevents over-tightening of flanges, protecting the valve seal from mechanical stress and extending its lifespan. A single actuator can cover all diameters from 1" (25 mm) to 4" (100 mm). Slide bearings on the disc pivots improve operational reliability, and visual indicators show the open/closed position. The intermediate flange design allows for easy removal and access, especially useful in long or fixed pipelines. Optional electro-pneumatic control with a positioner is also available.


DEYI butterfly valves are available in sizes ranging from DN25/1" to DN300/12". They are suitable for both industrial and household use, with multiple connection standards including DIN, 3A, SMS, ISO, IDF, BS, RJT, ASME, and BPE. The valves are constructed using high-quality materials such as 304, 304L, 316, and 316L. Various handle types are available, including pull handles and gripper handles, and gaskets made from silicone, EPDM, Viton, NBR, and PTFE ensure compatibility with different environments.
