• This device uses a force balance system to control the movement of the supply and exhaust valves
• Large supply and exhaust valves provide high forward and exhaust flows
• A balanced supply valve minimizes the effect of supply pressure variation
• An aspirator tube minimizes downstream pressure droop under flow conditions
• Forward flow capacity of 1800 SCFM (3058 m3/HR), which equates to a Cv factor of approximately 18 

in forward flow mode - ultra fast responsive operation
• Control sensitivity to 1" water column variation allows use in precision applications
• A separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing
• Optional increased sensitivity configuration with larger control diaphragm for more precision control at low setpoints
• Unit construction lets you service the Model 200 without removing it from the line
• Mounting bracket available - easy installation in the field
