DN300 – 12″ Valve
High-capacity flow control engineered for safe, uninterrupted operation in large-bore industrial lines.
The Ayvaz DN300 12″ Valve delivers precise flow regulation in large-diameter piping systems. In addition, its stainless steel body and sealing gaskets withstand high pressure reliably. Moreover, the flanged connection type simplifies installation on site. Therefore, it suits petrochemical and energy facilities where safety is critical.
This valve handles a maximum operating pressure of 16 bar and a maximum operating temperature of 200°C. Its ball-type design provides full-port flow, which minimises pressure loss across the line. Furthermore, the low-torque mechanism works with either manual handles or actuators. As a result, maintenance requirements stay low over long service intervals.
