Introduction
GENERAL:
The Series RER1 Proportional valve is ROSS CONTROLS’
latest product using closed loop control technology. It
incorporates many important standard features.
Standard flow rate of the valve is typically one scfm maximum.
When used with a volume booster a flow rate in excess of
1,000 scfm can be achieved.
Check the items below to see how cost-effective these valves
can be in your plant.
FEATURES:
• Fits into very small space
• Accurate to < ± 2.5% F.S.
• 0 – 10 volts DC analog monitor output
• NEMA 4 1P65 rating
• Accepts analog command signal inputs
• Proportional valve with regulator: control pressure ranges
from vacuum to 300 psig (20.7 bar)
• Flow rates can exceed 1,000 scfm
• Valve is insensitive to shock, vibration, or mounting
position
• Easily repairable in the field
