Beschreibung
Flanged-End Forged Steel Gate Valve
The flanged-end forged steel gate valve is designed for reliable isolation
service in high-pressure and high-temperature industrial pipelines. The valve
is available with raised-face or ring-type-joint flanged connections and
butt-welded ends.
Forged carbon steel, alloy steel and stainless steel materials are available
for water, steam, oil products, nitric acid, acetic acid and other industrial
media. The gate provides low flow resistance when fully open and reliable
shut-off performance when fully closed.
