SED Diaphragm Valves

Romynox delivers KMA diaphragm valve series SED for high purity applications and meets the highest standards for the pharmaceutical, food, fine chemical and cosmetic industries.

The KMA 190 is pneumatically operated and is used for sizes DN 4 to DN 15. The valve is predestined for applications with high purity, dirty and aggressive fluids, and gases. Smooth surfaces, no explored nuts, no edges, and outside self-draining in all assembly, positions describe the optimised wash down design. 

Features

  • Efficient plastic piston actuator with stainless steel distance piece
  • Direction of control air connection is mountable in 90° rotations
  • CDSA sealing concept
  • Flexible diaphragm suspension
  • Optical indicator
