AYVAZ KV-4 Gear Operated Lug Type Butterfly Valve DN300
Reliable flow isolation with minimal pressure loss and long service life.
The AYVAZ KV-4 Lug Type Butterfly Valve delivers an ideal flow control solution for industrial plants. In addition, its GG25 cast iron body and AISI316 stainless steel disc ensure a long-lasting, corrosion-resistant structure. Furthermore, the gear actuator enables precise and easy operation even at large diameters. With a nominal diameter of DN300, it suits a wide range of applications.
This valve controls fluid passage by rotating the disc around its own axis. Moreover, the elastomer gasket simultaneously seals against the pipe flange. Therefore, it offers effective performance with minimal pressure loss in fully open or fully closed positions. Consequently, it enhances system efficiency while saving energy. The body material is GG25 cast iron (lug type). The stem is SS420 for DN25–DN300 and SS431 for DN350–DN600. The actuator is gear-operated. Horizontal mounting is recommended for DN300 and above. The maximum operating temperature is 130°C.
