6" Gate Valve PN250 – Bolted Bonnet, OS&Y, Flanged Ends

This 6-inch (DN150) gate valve is constructed for high-pressure industrial applications, meeting DIN EN 1984 and DIN EN 1092-1 standards. With a bolted bonnet design and rising stem mechanism (OS&Y), it ensures reliable shut-off in high-pressure systems operating up to 250 bar. The valve body is cast steel (such as GS-C25 or ASTM A216 WCB equivalent), with metal seated internals for long-term durability under extreme conditions. Face-to-face length follows DIN EN 558 Series 1, and end flanges conform to Type B1 (PN250). Suitable for steam, oil, gas, and chemical applications with operating temperatures ranging from -10°C to +450°C.
