  • Overview 
  • ZMQ/ZSQ type pneumatic film (piston) shut-off valve has the advantages of light weight, sensitive action, small pressure drop loss, convenient disassembly and assembly.
  • The shut-off valve is connected to the adjusting mechanism by a multi-spring actuator, and the overall height can be reduced by about 30%, and the weight can be reduced by about 30%.
  • The valve body is designed according to the principle of fluid mechanics as an equal-section low-flow resistance flow path, and the rated flow coefficient is increased by 30%.
  • Balanced trims increase the allowable differential pressure of the shut-off valve.
  • The bellows seal form a complete seal against the moving stem, blocking the possibility of leakage from the media.
  • The piston type actuator has a large operating force and allows a large differential pressure.
