"FLEX CHECK" miniature check valves




High-performance miniature check valve for liquids and gases

  • Simple installation into cylindrical fluid ducts in metals
  • Sizes from 4.5 mm to 10 mm. Standard sizes 5.5 mm and
    8.0 mm diameter 
  • Opening pressures from 0 to 2 bar with 3 standard pressures: 0, 0.14 and 0.4 bar 
  • Large range of special options available on request 







Outstanding performance

  • Very high flow rates up to 5.2 l/min (8.0 mm at 2 bar) 
  • Flow rates in pulsation mode 2-3 times higher than conventional press-fit check valves 
  • Completely made of stainless steel, metal-metal gasket with low leak rate (<< 1 ssccm/min) 
  • Long service life of >15 million cycles 
  • Toolless design (patent pending) enables customer-specific designs with short delivery times and low-cost solutions, even for smaller series 
  • Parts are precision-machined on conventional high-production machines. This allows tight tolerances, e.g. in opening pressure (down to +/- 10%) and high process reliability. 


Easy assembly

  1.  2-stage drilling of the fluid channel
  2. Insertation of the valve
  3. Push-in of the pin

 

   



Individual solutions

Large range and special options such as:

  • Special opening pressures
  • Additional bezel
  • Metal filter (125 mcr)
  • Ceramic balls
  • Leak-free valve
