Range Spring
Operating PrinciplesWhen you adjust the Range Screw to a specific setpoint, the Range Spring exerts a downward force against the top of the Control Diaphragm. This downward force opens the Supply Valve. Output pressure flows through the Outlet Port and the Aspirator Tube to the Control Chamber where it creates an upward force on the bottom of the Control Diaphragm.
When the setpoint is reached, the force of the Range Spring that acts on the top of the Control Diaphragm balances with the force of output pressure that acts on the bottom of the Control Diaphragm and closes the Supply Valve.
When the output pressure increases above the setpoint, the Diaphragm Assembly moves upward to close the Supply Valve and open the Exhaust Valve, and output pressure exhausts through the Vent on the side of the unit until it reaches the setpoint.
• Sens i t i v i t y o f 0 . 05 " WC fo r Precision Control in low pressure applications
• Relief Valve provides high exhaust flows.
• Optional Low Bleed seat minimizes air consumption.
• An Aspirator Tub compensates for downstream pressure droop under flow conditions.
