Mainly including five types: angle pattern globe valve, bolted bonnet angle globe valve, handwheel operated globe valve, motorized globe valve and pn16 globe valve, angle pattern cast steel bolted bonnet flange handwheel operated globe valve can open and close by the advancement and retraction of the thread of the handwheel and the stem, lifting or lowering the valve plate connected with the valve stem. The closing member is driven by the valve stem and moves up and down along the central axis of the valve. The valve flap and the valve stem are designed as a single structure to prevent the possibility of the inner member from being flushed out of the valve body due to the pressure fluctuation of the pipeline, the structure is compact, and the use is safe.
1~12 Trim material
Flexible graphite+304/Flexible graphite+316
Simple and compact structure, short structure length, good manufacturing process and wide application range.
The inner medium passage of the valve body is straight through, the valve has good rigidity, the passage is smooth, the medium flows in a straight line, and the flow resistance is small.
One sealing face is designed on the valve body and valve disc, ensuring good manufacturing process and easy to maintain.
Back seal structure design ensures no medium leakage occurs in the stuffing box, reliable tightness and online replacement of packing.
Its valve stem sealing is realized by collaboration of flexible and woven graphite, ensuring a more reliable tightness.
Angle pattern globe valve, bolted bonnet angle globe valve, handwheel operated globe valve, motorized globe valve and pn16 globe valve are widely used in construction, petroleum, chemical, pharmaceutical, textile, metallurgy, energy systems and other pipelines as a regulating and intercepting device.
