Details summary
Pilot operated check valve for hose burst protection, cylinder port mounted (Cmatic MV 45)
  • pdfDatasheet

Should a sudden pressure failure happen, this valve stops the cylinder movement. When the valves are assembled in pairs on the cylinder ports, the cylinder piston stops rapidly and the load stays in place.

By operating the separate override device, the piston stroke can be reset manually, which is particularly important during a set-up phase or in case of air shortage. The manual control is sold separately: 11000015-MA/RA for the M5 pilot port and 11000016-MA/RA for the G1/8 pilot port.

  • Maximum pressure: 10 bar
  • Temperature range: -20…+80 °C
  • Body: brass UNI EN 12164 CW614N, nickel plated
  • Piston: stainless steel AISI 304
  • Spring: stainless steel AISI 302
  • Seals: NBR-PU
  • Gasket: PA6
  • Silicone free, RoHS and REACH compliant
  • Application field: pneumatic installations fed with filtered, lubricated air

Flow values are measured at 6 bar / ∆p 1 bar and apply to the unidirectional U version. The required pilot pressure increases with the inlet pressure: approximately 1.5 bar at 2 bar inlet, approximately 4 bar at 10 bar inlet.
