  Features：

  Seat and valve body separable, easy to repair and economical

  Umbrella-type recoil disk and adjusting ring can effectively improve the lift force, and the valve disc can fully open and release the medium at small over-pressure so as to protect the equipment.

  Adjusting ring can adjust satisfactory on-off pressure difference

   Proper selection of the material of the recoil disk, guide sleeve, valve stem and adjustment screw, and proper selection of the clearance to ensure flexible valve motio

  Hardfacing cemented carbide at sealing surface ensures corrosion resistance, high sealing performance and long service life of safety valve after surface finishing

  Bellows in balanced bellows relief valves eliminate the impact of back pressure fluctuations on valve performance and also ensure that springs and other internals are protected from media corrosion

  Springs and bellows shall be selected and processed, and strict testing and inspection shall be carried out.
