  • The compact overall structure
  • Rapid act,huge thrust,little friction
  • The effective area of 280~1600 cm2 can be chosen.
  • The gas source range(spring range)of 0.14~0.34 Mpa can be selected. 
  • The built-in spring is replaced to change the scope of work of the gas source. 
  • The standard film cover is the plastic coated steel plate,or the optional can be stainless steel
  • The stem can be connected by screw clamping.
  • The clear hand wheel mechanism can be chose,choosing the maximum and minimum travel mechanical limit.
  • The maximum supply pressure is 0.6Mpa,and it can continuously work under the temperature of -40~120.
