Cast Steel Stainless Steel Angle Type Globe Valve For Water Steam And Oil Use
Product introduction:
A globe valve, also known as a shut-off valve, is a forced sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to not leak. When the medium enters the valve from below the valve disc, the resistance that needs to be overcome by the operating force is the frictional force between the valve stem and packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open it, so the diameter of the valve stem should be larger, otherwise it will cause the valve stem to bend. The opening and closing part of a globe valve is a plug shaped valve disc, with a flat or conical surface on the sealing surface. The valve disc moves in a straight line along the centerline of the valve seat. Due to the relatively short opening or closing stroke of the valve stem and the highly reliable cut-off function, as well as the proportional relationship between the change of the valve seat opening and the stroke of the valve disc, this type of valve is very suitable for regulating flow.
The inlet and outlet channels of the J44H angle globe valve are not in the same direction and form a 90 ° right angle. When the fluid passes through the valve, it will change the direction of the fluid and be installed at the corner of the pipeline system, which not only saves 90 ° elbows but also facilitates operation. Therefore, this type of valve is suitable for use in the synthetic ammonia production system and refrigeration system of fertilizer plants.
