OEM Gost Cast Steel Gate Valves PN 16 DN 50 Manual For Steam And Heat Conduction Oil

GOST-Compliant Cast Steel Flange Gate Valve for Steam & Heat Conduction Oil
This manual-operated gate valve is designed to GOST standards, offering robust performance in high-temperature steam and heat conduction oil systems. With a temperature range of -20°C to 425°C and a pressure rating of PN 16, it ensures reliable sealing and durability under demanding conditions. The DN 50 nominal bore size accommodates medium flow control in industrial pipelines, while the cast steel (WCB) body provides exceptional resistance to thermal stress and corrosion.

The valve features flanged connections (ANSI/GB/DIN standards) for easy integration into existing piping systems, ensuring leak-proof performance in steam distribution, thermal oil circuits, and other high-temperature applications. Its manual handwheel operation allows precise flow regulation, supported by a resilient wedge design that minimizes wear and extends service life
