                  [Valve features]

                  1, the use of floating seat, two-way opening and closing, reliable sealing, open and close flexible.
                  2, the gate has guided bars to give precise guidance, while sealing surfaces are spray welded carbide, erosion resistance.
                  3, the valve carrying capacity is high, the passage is straight through type. When fully open, it is connected with the gate guide hole and straight pipe, and the flow resistance is very small. The valve stem adopts compound packing and multiple sealing, so that the sealing is reliable and the friction is small.
                  4, close the valve, the gate down to the bottom, due to the role of medium pressure, the import side of the sealing seat into the direction of the gate, forming a larger seal than the pressure, thus forming the first seal. At the same time, press the gate to the outlet end sealing seat and become double seal.
                  5, the sealing parts are grease device, when the valve leaked, it can be sealed urgently.


                  [Adaptive condition]
                         No diversion hole plate valve has reliable sealing performance, opening and closing torque is small, with anti sulfur resistance, long service life, can pass the ball clean wool pipeline etc; opening and closing device for piping system for water, oil, natural gas, steam and other non corrosive and corrosive medium, especially suitable for petrochemical oil and gas pipelines etc..
