• Minimum differential pressure:
Model 2100, 2200 & 2300 ......15 psi (1.0 bar)
Model 2150, 2250 ...................3 psi (.2 bar)
• Maximum differential pressure 150 psi (10.3 bar). A two
stage reduction should be used for pressure drops

Series 2000 Main Valves
• For continuous or dead end service within .01% leakage
of the valve’s rated capacity
• Packless construction eliminates many service problems
• Complete range of port sizes:
—Full
—Normal
—Reduced
—Low pressure {Models 2150 & 2250}
• Positive travel stop and back up of diaphragm prevents
over pressurizing from low pressure side
• Maintains accurate and stable control of pressure
or temperature
• Two-ply stainless steel diaphragm provides greater
accuracy of control over the entire capacity range
and a longer life
