The two openings for medium flowing in and out are in the same direction, forming an angle of 180°. This kind of globe valve makes the destructiveness of flowing state become relative less, thus reducing the pressure loss caused by the valve correspondingly. Use the slight flexible deformation generated by the extrusion to the metal seal ring at the bonnet to compensate the deviation of the sealing face angle generated during processing, thus ensuring reliable tightness.

Application
|
|
Compact and reasonable product structure, reliable tightness, excellent performance and attractive appearance.
Generally, lift is just 1/4 of the valve seat port, ensuring a short opening and closing time.
Only one sealing face is designed on the valve body and valve disc, ensuring good manufacturing process and easy to maintain.
The valve is designed as a back seal structure, ensuring 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.
