Favorite
The directly-controlled Rotork Fairchild Model 67 stainless steel regulator precisely controls fuel pressures in ranges from minus 6 to 60 psi. The large diaphragm actuator with directly controlled valve gives excellent response characteristics with very low hysteresis. 

High precision control is achieved by its forcebalanced valve, with a newly developed patented smooth running seal system.

Specially developed for the high precision and reliability requirements of modern engine test equipment, the M67 is suitable for all fuels such as gasoline, diesel, biodiesel (RME), aviation fuel, methanol, ethanol, petrol mixtures E5 to E100 and diesel mixtures B5 to B100.
Features
  • High Accuracy
  • Extremely Low Droop Under Flow
  • Full Corrosion Resistance for All Fuels and Mixtures
  • No Supply Pressure Effect
  • Allows Quick Fuel Changeover
  • Washdown and Internal Purge Capability
