Diaphragm Valve (Union)

由令式隔膜閥
Description:

  • Pressure rating: 100 PSI
  • Smooth operation with clear indication of opening / closind through the gauge cover.
  • Low maintenance cost with replaceable diaphragm and long service life
  • Adjustable stopper can avoid over tightening

Caution! The valve is completely closed when handwheel can’t turn more with normal torque, but it will cause the unrecoverable divulsion of diaphragm if the handwheel is continuously forced to turn in such above condition!

 

Character:

  • Do not recommend to service or test with compressed air or gases.
