Product Details

National standard flange globe valveThe opening and closing component is a cylindrical valve disc with a flat or conical sealing surface, and the valve disc moves in a straight line along the centerline of the fluid. The national standard globe valve is only suitable for fully open and fully closed, and is generally not used to regulate flow. When customized, it is allowed to be adjusted and throttled. Nominal Pressure1.6MPa-16.0MPaWorking temperature-29～550Cut off or connect pipeline media in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries at ℃. The driving methods include manual, gear transmission, electric, pneumatic, etc.
