          ?Liner Sealing face – to get lower operate torque.





          ?Position “A”:

          Most factories’ design is the same lever sealing face.

          while when the valve closed, the increasing inlet pressure will image.pngpush the disc shift and press the valve body, which will cut thedisc rubber of position “A” during long term use.

          IVALVE has been aware of this defect and improve the design to avoid the hurt mentioned above,and by the new design,thedisc service life has been extended.

          Technical Data

          Attention:

          1.The valve is installed independent of the flow direction of the medium.

          2.?After the valve is assembled, the thread of the bolt/stem shall be greased to prevent corrosion and facilitate subsequent disassembly.

          3.?Do not use the valve for pipe pressure regulation, gate valves generally play the role of a switch, to achieve a good adjustment effect, it is recommended to choose a professional regulating valve, water erosion will affect the service life of the valve disc.

          4.?Do not use valves with EDPM for gaseous fluids.


          Installation instructions

          1.?Notice of water stop shall be issued before construction.

          2.?The water in the road should be avoided in the front row of construction.

          3.?Electricity for construction must be guaranteed.

          4.?It is strictly prohibited to use hand wheel, handle and transmission mechanism for hoisting and collision is strictly prohibited.

          5.?Lubricate the valve at least once a month if it is in frequent use.
