GB Flanged Globe Valve (GB Flanged Globe Valve) is a common industrial valve mainly used to control the flow of fluids. The following is a basic introduction to the national standard flange globe valve:

Specification: GB flanged globe valve nominal diameter range from DN50 to 400 mm, nominal pressure from PN10 to 64 mpa, operating temperature range from -196 ° C to +600 ° C.

Drive mode: It can be operated manually, bevel gear or electrically.

Materials: The main materials include carbon steel and stainless steel.

Design and manufacturing standards: GB flange globe valve design and manufacturing comply with GB12235 standard, structure length comply with GB12221 standard, flange size comply with GB9113 and JB79 standards, pressure-temperature rating comply with GB9131 standard, test and inspection comply with GB/T13927 and JB/T9092 standard.

Sealing performance: GB flanged globe valve is a forced sealing valve, when the valve is closed, pressure needs to be applied to ensure that the sealing surface does not leak. In recent years, the advent of self-sealing valves has changed the direction of the medium cut-off valve, thereby reducing the force required when the valve is closed, and correspondingly reducing the diameter of the valve stem.

Pressure test: The pressure test of GB flanged globe valve includes strength test and seal test, the specific pressure value varies according to the nominal pressure, for example, the nominal pressure of 1.6 mpa corresponds to the strength test pressure of 2.4 mpa, and the seal test pressure of 1.8 mpa.

Application: GB flanged globe valve is widely used in petroleum, chemical, power, paper and other industries, suitable for controlling general to harsh working conditions.

Features: GB flange globe valve has the characteristics of simple structure, easy maintenance, short stroke, good sealing, low resistance, long service life and so on.

Disc shape: the valve disc is usually cylindrical, the sealing surface can be flat or conical, and the valve disc moves in a straight line along the center line of the medium, but the GB flange globe valve is not suitable for regulating flow.
