![]() ![]() This type of plunger valve is a radial seal, which is realized by two spring loaded sealing rings sleeved on the polished plunger. It is suitable for media which require vacuum circumstance such as steam, flammable, explosive, thermal oil, high purity, toxic and atc The bellows are welded to the stem to maintain stable operation performance, to avoid stem vibration caused by valve plug vibration. ![]() If the bellows fails, the stem packing will act as secondary seal. The other end of bellow is installed between the valve body and bonnet to form a static seal. The bellows globe valve uses a bellows structure, and the lower end of the stainless-steel bellows is welded to the valve stem to prevent the process fluid from corroding the valve stem. It is designed by automatic roll welding to form a metal barrier between the fluid medium and the atmosphere to ensure zero leakage of the valve stem. Therefore, this type of valve is most suitable for use in synthetic ammonia production systems and refrigeration systems in chemical fertilizer plants.īellow globe valve is also called bellow seal globe valve. The biggest advantage of the angle globe valve is that the valve can be installed at the right angle of the pipeline system, which saves 90° elbows and is easy to operate. It is very suitable for alumina production pipelines, and is also suitable for pipelines with slurry medium. The sealing surface of the valve seat and disc can be welded with hard alloy for erosion and corrosion resistance. It is the smallest flow resistance among globe valve. Y type globe valve will not change the direction of flow. The split body type Y globe valve uses two valve bodies to sandwich the valve seat between them, which is convenient for maintenance. The valve body can be made integral or split body. The valve stem and the flow path of the Y type globe valve form a certain angle, and the sealing surface of the valve seat and the inlet and outlet flow path also have a certain angle. It is the most commonly used valve in the industry. Compared to gate valve, the structure of the globe valve is straight forward, and it is easier to maintain. The degree of throttling height is minimum and the process performance is optimum. During the open/close process, the friction between the sealing surfaces is small, minimizing wear and tear. It relies on the valve stem to navigate the valve disc towards the sealing surface of the valve seat, fully shut off the flow. This design has low coefficient of flow and pressure drop. ![]() The medium inlet and outlet flow path of the T Pattern Globe valve are 180° in the same direction. Straight through flange globe valve ※ Straight Through/TEE Pattern/Z-Body Globe Valve Common problems and maintenance of globe valveġ. Performance and Application of Globe ValveĦ. Construction of a Globe valve and Working Principlesģ. The valve disc and the valve stem of the globe valve are designed flexible connection to facilitate the valve disc and the valve stem fitting.Ģ. ![]() In order to close the valve tightly, the matching surface of the valve disc and the valve seat should be grinding, and the corrosion-resistant and wear-resistant materials such as Stellite 6 and stainless steel can also be welded on the sealing surface. The valve disc and the valve seat is the sealing parts of the globe valve. The most commonly used is in chemical production. Available in the following anodized finishes: black, blue, gun metal, orange, purple, red, and silver.The Globe valve is used to cut off the flow of the medium and is suitable for occasions that need to be throttled frequently. Fits rim hole diameter: 11.5MM (.453 diameter) Same size as a rubber valve stem cap TR413. OUR SPIKE AND BULET VALVE STEM CAPS WILL FIT ON THESE VALVE STEMS These will fits most OEM and aftermarket wheels found In cars, trucks, SUV's, ATV's, trailers, motorcycles etc. These are less than half the weight of steel valves. These will withstand the multiple and frequent pressure checks you'll need to take at the track! They come in a variety of colors to compliment your wheels, and will outlast conventional rubber valve stems. They are a great addition to any high-performance wheel application. The VMS Racing valve stems are precision-made valve stems designed for the rigors of racing and high performance street use. VMS Racing bolt-on aluminum valve stems are available in many colors. ![]()
