Piston Valve DN50 PN40
Zero-leak sealing and long service life under heavy-duty conditions.
Piston Valve DN50 PN40 is designed to control fluids under high pressure in industrial plants. In particular, it provides excellent sealing in fully open or fully closed positions. Moreover, its GGG40 ductile iron body delivers long-lasting performance in heavy-duty conditions. Furthermore, the stainless steel internals provide maximum resistance to corrosion. The valve operates through a piston mechanism that moves parallel to the flow direction. As a result, this design guarantees precise flow control and near-zero leakage. In addition, the flanged connection type speeds up installation and minimizes downtime. Consequently, operational efficiency increases.
The working principle relies on a piston moving parallel to the fluid path, ensuring tight shutoff and accurate regulation. The GGG40 ductile iron body resists mechanical stress, while stainless steel internal parts withstand corrosive media. The flanged connection simplifies mounting and reduces maintenance time. This valve handles water, steam, oil, compressed air, and chemical substances. Its operating temperature range spans -20°C to +200°C, depending on the application type. The PN40 pressure class supports a maximum of 40 bar. Therefore, it suits demanding industrial circuits that require reliable isolation and flow management.
