The GEMÜ 655 2/2-way diaphragm valve has a metal handwheel and is manually operated. The valve body has a full bore design.

Key features

  • High mechanical stability
  • High flow rate due to straight through flow
  • Can be retrofitted with a pneumatic actuator
  • Non-rising, robust metal handwheel
  • Thrust-bearing handwheel for larger diameters
  • Body available with hard or soft rubber lining
  • Minimal deadleg internal contour for good flow conditions and high Kv values
  • Particularly suitable for media with high solid matter content
  • Optimally suited compressor
  • Threaded diaphragm pin for optimum diaphragm seat and long service life
