BELIMO Electric Butterfly Valve - D6 Butterfly Valve Series and Electric Actuators Full Range of Electric Actuators BELIMO's high-quality, cost-effective D6 series butterfly valves provide customers with a wider selection of valve options. The main applications of butterfly valves in HVAC systems include: chilled water systems, cooling water systems, automatic switching systems, large air handling units, differential pressure bypass control, etc. The cost-effective butterfly valves and a comprehensive range of electric actuators offer economical solutions for customers. Performance and Features 1. Utilizes advanced pinless connection technology, resulting in a sturdy and compact structure. The disc features automatic centering (up-down, left-right), reducing torque under complete airtight conditions and extending service life. The valve seat lifespan is 2-3 times that of ordinary centerline butterfly valves. 2. Employs an advanced spherical sealing pair for more reliable sealing. The spherical seal ensures smooth transition during valve opening and closing, reduces friction, lowers torque, and allows for the selection of low-power driving devices, reducing user costs. 3. High-quality materials, genuine and reliable. The valve body is made of ductile iron, with a stainless steel valve shaft. The disc is coated with a nylon anti-corrosion layer, offering excellent wear reduction and self-lubrication, further reducing driving torque. 4. The flange sealing surface of the valve seat features a wide edge and large arc design, making the valve adaptable to both sleeve-type and welded flange connection requirements, suitable for any standard flange connection. This simplifies installation and ensures a tight seal. 5. Tongue-and-groove valve seat ensures accurate connection and fit between the valve body, valve seat, and disc. Facilitates easy replacement of the valve seat and can be reliably used in vacuum conditions. 6. Carefully matched and combined with BELIMO's complete series of electric actuators, it delivers reliable performance and the most cost-effective solution.
