AYVAZ KV-4 Gear Operated Lug Type Butterfly Valve DN600
Gear-operated large-diameter flow control with dependable sealing and low operating effort.
The AYVAZ KV-4 Lug Type Butterfly Valve DN600 provides a strong flow control solution for industrial plants. In addition, its gear-operated actuator allows precise, low-effort use even on large-diameter valves. It stands out with high sealing performance, particularly in water, gas and wastewater lines. Furthermore, its compact body saves installation space.
The working principle relies on a disc rotating around the shaft to regulate fluid passage. Moreover, the elastomer seat also performs the sealing duty on the pipe flange. As a result, this design delivers high efficiency with minimum pressure loss in the fully open position. Consequently, energy losses in the system decrease and long service life is achieved. Body material is GG25 cast iron in lug type; the shaft is SS420 for DN25–DN300 and SS431 for DN350–DN600. Mounting is recommended in the horizontal position for DN300 and above.
