FAIRCHILD - Pressure Regulators
Rotork Fairchild Model 18 Vacuum Relief Regulator is designed for systems that require system vacuum control up to full vacuum. The Model 18 Vacuum Relief Valve uses a force balance principle to open the relief valve and allow atmospheric air to lower vacuum levels when the set point is exceeded.
Features
• Full vacuum capability - accurate control in vacuum applications
• Control sensitivity of less than 1/8" water column allows use in precision applications
• Stability of regulated vacuum or pressure is maintained under varying flow conditions through the use of an aspirator tube which adjusts the inner valve in accordance with the flow velocity
• A balanced supply valve to deliver consistent and reliable accuracy
• 30 in Hg, 762 Torr, 102 kPa maximum supply vacuum
• Three relief vacuum ranges from 4 in Hg, 140 mBar, 14 kPa, up to 30 in Hg, 1000 mBar, 100 kPa
• Up to 8 SCFM, 68 m3/hr flow capacity
• Separate control chamber eliminates hunting and buzzing
• Unit construction permits you service the Model 18 without removing it from the line
