| Model 17 Vacuum Regulator | ||
| Model 17 | Features The Model 17 Vacuum Regulator is designed for systems that require system vacuum control up to full vaccum, Օ Control sensitivity of 1/2" water column allows use in precision applications. High flow capacity Օ A balanced vacuum Valve minimizes the effects of variation. An Aspirator Tube compensates downstream vacuum droop under flow conditions. Օ A separate Control Chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing. Unit construction lets you service the Model 17 without removing it from the line. Օ Mounting Bracket is available. Operating Principles When you adjust the Range Screw to a specific setpoint, the Range Springs exerts a downward force on the top of the Control Diaphragm. The Negative Bias Spring creates an upward force on the bottom of the Diaphragm. The upward net force opens the Relief Valve (vacuum supply) to let Vacuum flow from the Outlet Port to the Exhaust Port, As the setpoint is reached, the decrease in pressure lets the Diaphragm Assembly move downward to close the Relief Valve (vacuum supply). When the Vacuum increases above the set-point, the Diaphragm Assembly moves downward to open the Supply Valve that adds positive pressure to the system to maintain Output pressure. For more information, see cross sectional diagram. Outlet pressure is maintained as a result of balance between forces acting on the top and bottom of the Diaphragm Assembly. | [ MCCtlMM |
