Flange globe valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak.

In physical and chemical experiments, oxygen shut-off valve often uses oxygen, nitrogen, hydrogen, argon and other gases. These gases are generally stored in dedicated high-pressure gases.

The opening and closing part of the angle globe valve is a plug-shaped valve disc, the sealing surface is a plane or a conical surface, and the valve disc moves linearly along the center line of the fluid. The movement form of the valve stem includes a lifting rod type (the valve stem rises and falls, and the handwheel does not rise and fall), and there is also a lifting rotating rod type (the handwheel rotates and lifts together with the valve rod, and the nut is arranged on the valve body). The bellows globe valve is only suitable for fully open and fully closed, no adjustment and throttling are allowed.

Welded shut-off valve and pipeline connection adopts welded structure. The sealing surface is not easy to wear and scratch, with good sealing performance and long service life. Compact structure, good opening and closing, small height and easy maintenance. It is suitable for water and steam oil pipelines, and has the characteristics of high temperature resistance and high pressure resistance.

Once the disc of the threaded globe valve is in the open state, the contact between its valve seat and the sealing surface of the disc is no longer in contact, and has a very reliable cut-off action, so this valve is very suitable for medium cut-off or adjustment. and throttling usage.
