A105 /A105N Flanged End Forged Steel Globe Valve
Flange forged steel Globe
valve is suitable for the pressure PN16~160 working temperature -29ºC~550ºC of petroleum, chemical, pharmaceutical, chemical fertilizer, power industry and other working conditions of the pipeline, flange forged steel stop valve is suitable for water, oil, steam, acid medium.
Flange globe valve types according to the position of the valve stem threads are divided into external thread type, internal thread type. According to the flow direction of the medium, there are straight-through, straight-flow and Angle. The globe valve is divided into sealing forms, including packing globe valve and bellows globe valve. Globe valve structure: globe valve body structure is straight through, straight flow and right Angle. Straight-through is the most common configuration, but it has the greatest fluid resistance. Direct flow fluid has less resistance and is mostly used for fluids containing solid particles or large viscosity. Right-angle valve body adopts forging, suitable for smaller pass, higher pressure of the globe valve.
Merit
1. Simple structure, convenient manufacturing and maintenance.
2. Small working stroke and short opening and closing time.
3, good sealing, small friction between sealing surfaces, long service life.
Demerit
1, fluid resistance, open and close the required force is large.
2. It is not suitable for medium with particles, large viscosity and easy coking.
3, poor regulation performance
