Product Description

The Stainless steel forged oxygen globe valve is a mandatory sealing valve. When the medium enters from below the valve disc, the resistance that the operating force needs to overcome is the friction force of the valve stem and the packing and the thrust generated by the pressure of the medium. The force of closing the valve is greater than the force of opening the valve, so the force of the valve stem The diameter should be large, otherwise the valve stem will bend up failure.

Product Structure Characteristics

When the Stainless steel forged oxygen globe valve is opened, when the opening height of the valve flap is 25% to 30% of the nominal diameter, the flow has reached the maximum, indicating that the valve has reached the fully open position. In recent years, the flow direction of the stainless steel oxygen shut-off valve has changed from above the valve clack to enter the valve cavity. At this time, under the action of the medium pressure, the force to close the valve is small, but the force to open the valve is large. The diameter of the stainless steel oxygen shut-off valve stem can be corresponding To reduce.

Advantages

The Stainless steel forged oxygen globe valve has the characteristics of good flame retardancy, good electrical conductivity, fast heat transfer, tight structure and oil-proof safety and reliability.

DESCRIPTION：
Forged steel globe valve is a commonly used shut-off valve, mainly used to connect or cut off the medium in the pipeline, and generally not used to regulate flow. The cut-off valve is suitable for a wide range of pressure and temperature. This valve is suitable for small diameter pipelines, with a sealing surface that is not easily worn or scratched, good sealing performance, small valve disc travel during opening and closing, short opening and closing time, and small valve height

Main features:
Forged steel globe valves come in three types of valve cover designs.
The first type is a bolt type valve cover, which is designed according to this design form. The valve body is connected to the valve cover with bolts and nuts, and is sealed with a spiral wound gasket (made of 316 clamp flexible graphite). When customers have special requirements, metal ring connections can also be used.
The second design form is a welded valve cover. According to this design form, the valve body and valve cover are connected with threads and fully welded for sealing. When customers have special requirements, fully welded connections can also be used.
The third type is a pressure self tightening valve cover. Valves designed according to this design form have a threaded connection between the valve body and the valve cover, and an internal pressure self sealing ring for sealing.
