 The two opening ways for medium flowing in and out are at the same direction, forming an angle of 180°. This kind of globe valve makes the destructiveness of flowing state be relative less, thus reducing the pressure loss caused by the vale correspondingly |  The gate valve refers to a valve opened or closed with its closing member (the disc) moving perpendicularly along the passageway axis of pipe-line. |  We currently can produce cryogenic gate valves for working temperature down to -196℃ which are widely used in LNG、LPG、air separation and other low temperature industry. |
 The pressure seal valves are designed in accordance with API600 and ASME B16.34 for service of high temperature and high pressure and are widely used in fossil fuel power plant. |  The two sealing faces of a slab gate valve are perpendicular to the pipeline axis, its closing member have double discs | |
 The two sealing faces of a slab gate valve are perpendicular to the pipeline axis, its closing member is a single disc |  Cryogenic ball valve is suitable for service of working temperature down to －196℃, such as LNG, LPG, and air separation industry. |  Principle of the cast steel floating ball valve: This kind of ball valve has a floating ball supported by two valve seats. Under the medium pressure effect, a certain displacement can be generated by the ball itself so as to be pressed onto the seat seal ring at the outlet, guaranteeing tightness at the outlet |
