The DN50 PN16 Flanged Gate Valve is a reliable and durable valve designed for precise flow control in medium-pressure systems. Constructed from high-quality carbon steel (WCB) or stainless steel (CF8/CF8M), it is resistant to corrosion and wear, ensuring a long service life in demanding environments.
This gate valve features a soft sealing design with PTFE or RPTFE seats, offering superior sealing capabilities and preventing leakage under pressure. It is designed with a non-rising stem to minimize the space required for installation, making it ideal for underground or confined installations.
The valve is equipped with flanged ends, allowing for secure and easy integration into pipe systems. It is available with manual operation, gear operation, or with electric or pneumatic actuators for more complex automation. The DN50 PN16 Flanged Gate Valve is commonly used in water supply systems, oil & gas industries, petrochemical plants, and power generation facilities.
With a PN16 pressure rating, this valve is suitable for applications that require reliable shutoff in medium-pressure pipelines. It is manufactured in compliance with international standards, such as API 600 and ASME B16.34, ensuring its performance and safety.
