GLOBE VALVES

MstnLand is a reliable globe valve china supplier. We provide high-quality industrial electric globe valves, including API globe valve, DIN globe valve, ANSI bellow seal globe valve, Angle globe valve, Y type globe valve, and Pressure seal globe valve etc. Our globe valve factory has the capability to manufacture various globe valves types you need.

The globe valve only allows one-way medium flow and it relies on valve rod pressure to make both the sealing surface of valve disc and the valve seat tightly fit and then prevent medium flow. As an experienced and tested globe valve manufacturer, Mstnland offers globe valves that are featured by elbow saving and easy operation and can be installed in the bend of the pipeline system.

As one of the most important cut-off valves, the globe valve plays an important role in the aerospace field. As an important component of aerospace equipment, the globe valve realizes the functions of medium delivery, cut-off, and adjustment, and its sealing performance directly affects the safe and reliable operation of aerospace equipment. Studying the influencing factors and rules of the sealing characteristics of typical globe valves has guiding significance for the structural design of the valve sealing pair, so as to improve the sealing performance and reliability of the valve.

Globe Valve Maintenance

1. The globe valve should be placed in a dry and ventilated area, and both ends need to be blocked. And in order to prevent the valve from rusting and fouling, a layer of anti-rust oil must be painted on the surface of the globe valve. In addition, the mark on the valve stem must be complete and clear, besides, lead seals and caps are indispensable.

2. After installing the globe valve, check it regularly to see whether the sealing surface is worn, whether the valve stem and nut are worn, whether the packing is invalid, etc., if any of the above problems are encountered, the globe valve needs to be repaired and replaced, and the seal must be sealed after replacement. Only after passing the test can it be assembled.

3. When the globe valve is in use, it should be selected according to the area. For high temperature and high-pressure systems such as thermal power plants or nuclear power plants, balance or plunger globe valves should be selected, and small globe valves should be selected when applied in needle valves, sampling valves or pressure valves. And if the adjustment accuracy is not high and the pipe diameter is small, you can choose a flow adjustment globe valve. On the contrary, if it is a synthetic production, you can choose a high-pressure valve.

4. When the globe valve is in operation, ensure that all valve parts are complete and intact, especially flanges and bracket bolts. The bolts should be intact and not loose. If the nut on the handwheel is loose, tighten it immediately. And when the handwheel is lost, it cannot be replaced with an adjustable wrench and should be provided in time. In addition, the packing cover must not be skewed, otherwise, it is easy to be polluted by wind, snow, dust, etc.

Globe Valve Operation

Not only should we learn to install and maintain the globe valve, but also we must be able to operate it.

During operation, if the operation is found to be too laborious, the reason should be analyzed. If the packing is too tight, it can be properly loosened. If the valve stem is skewed, personnel should be notified to repair it. In some globe valves, when closed, the closing part is heated and expanded, which makes it difficult to open; if it must be opened at this time, the valve cover can be loosened half a turn to one turn to eliminate the stress on the valve stem, and then move the handwheel.
