Pressure Seal Globe Valve

Product Description:

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。
