Manual hard seal knife gate valve pz73h

  Product features of knife gate valve: knife gate valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, light and flexible operation, small volume, smooth channel, small flow resistance, light weight, easy installation and disassembly
It can work normally under the working pressure of 1
0mpa-2
5mpa and the operating temperature of - 29-550 ℃ Knife gate valve: suitable for powder and slurry fluids in general petrochemical and other food industries, cement, papermaking, environmental protection and other industries The gate of knife gate valve has the function of shearing, which can scrape the adhesive on the sealing surface and automatically remove the sundries
The stainless steel gate valve can prevent the seal leakage caused by corrosion Knife gate valve: product features 1
Ultra short structural length, saving materials, and greatly reducing the overall weight of the pipeline system 2
It occupies less effective space, can effectively support the strength of the pipeline, and can reduce the possibility of pipeline vibration 3
The gate is made of austenitic stainless steel, with greatly improved corrosion resistance, which can effectively prevent seal leakage caused by gate Corrosion 4
The upper sealing packing adopts flexible PTFE ， Reliable sealing, light and flexible operation 5
The ram has the function of knife switch, which can effectively cut off all kinds of sundries in the medium
Installation and use:
1) Before installation, check the valve cavity and sealing surface, and no dirt or sand is allowed to adhere;
2) Bolts at all connecting parts shall be tightened evenly;
3) Check that the packing part is required to be compressed to ensure the tightness of the packing and the flexible opening of the insert plate;
4) Before installing the valve, the user must check the valve model, connection size and pay attention to the medium flow direction to ensure consistency with the requirements of the valve;
5) When installing the valve, the user must leave the necessary installation space for the valve drive;
6) The wiring of the driving device must be carried out according to the circuit diagram;
7) The valve must be maintained regularly without collision and extrusion, so as not to affect the sealing performance
