PN 10 – DN 25 - 200 mm


The M-20 series is a line of composite material, diaphragm-operated hydraulic control valves with a working pressure up to 10 bar.

The polypropylene construction is suitable for industrial installations in mining and processing plants.
The M-20 utilizes the elliptic shaped diaphragm for a smooth and accurate closing and opening over a wide range of flows, with drip-tight sealing.

It integrates well with a wide variety of regulating control pilots, solenoids and control accessories.
The M-20 is compatibly designed for water level control, flow control, electric & remote control, pressure reducing & pressure sustaining operation, in addition to a full range of tailor-made solutions. The control valve combines high flow capacity with exceptional hydraulic performance.

  • Positive drip-tight sealing is guaranteed by the elliptic diaphragm design and its resilient sealing surface.
  • Unique in the R-20 Series
  • Available in sizes up to 8”
  • Separate double chamber for 6”-8” valves
