    7.The working pressure, woking temperature, viscidity of the medium should not exceed the specified scope.
    Maintenance
    1.Before disassembling the pneumatic valve, drain the fluid inside the cylinder and the medium pressure of valve. Thoroughly clean the medium if it involves flammability and explosibility with high temperaure and high pressure or it is toxic or corrosive.
    2.Step of Disassemble pneumatic valve:
    A.Disassembly of cylinder:Take off the locking ring, lift the cylinder and take it out. The piston, spring, position indicator and stem are visible.
    B.Disassembly of valve body:Ioosen with spanner at the end of the valve cover.
    C.Disassembly of seals:Disassemble the valve body, and the seals are at the end of the stem; remove the screw that fasten the seals.
    4.Then assemble the valve step by step refer to the step of disassembling.
    5.The parts such as seals, locking ring and spring should be assembled correctly. Tighten the connection properly, do not damage the film and valve seat.
    6.The maintained valve must pass the pressure and leakage test, and then it can be put into use.
