  • Specifications

The opening and closing parts of the angle globe valve are plug-shaped valve disc, the sealing surface is flat or conical, and the flap moves linearly along the centre line of the fluid. Angle globe valve is also called angle valve, the inlet and outlet channels of the globe valve are not in the same direction, forming a 90° right angle. This type of globe valve causes the medium passing through the valve to change the direction of flow, so a certain pressure drop will occur.

There are two kinds of stem movement mode. One is lifting stem type (the stem is raised and lowered, the handwheel is not raised and lowered). The other is lifting rotary stem type (the handwheel and the stem rotate and lift together, the nut is located on the valve body).

Angle globe valve is suitable for the pipeline of petroleum, chemical, pharmaceutical, fertiliser, electric power, recycling equipment, gas supply, cooling and freezing system, boiler steam system, hot oil system industry, etc. It can be used under various working conditions with nominal pressure 150LB~2500LB and working temperature -40~500℃, cut off or connect the pipeline medium. The angle globe valve has a reasonable structure, reliable sealing, excellent performance, and beautiful appearance. The sealing surface is welded with hard alloy, wear-resistant, corrosion-resistant, no leakage, good anti-friction performance and long service life. The valve stem is tempered and the surface is nitrided. It has good anti-corrosion and anti-friction performance, as well as good sealing performance and more reliable.

The greatest advantage of the angle globe valve is that it can be installed at the corner of the piping system, which saves 90° elbows and is easy to operate. Angle type globe valve is most suitable for use in synthetic ammonia production systems and refrigeration systems in fertilizer plants. Due to the high pressure required in the refining, synthesis, and compression sections of the ammonia synthesis process, 2500LB is very common. So it is made of forged steel, internal and external sealing requirements are high, the force of the fluid on the disc is large, and the driving force during switching is required to be as small as possible. The angle globe valve can meet the above requirements.
