Type 700 - High Flow Capacity Precision Air Pressure Regulator0 pages
Type 700 Precision Air Pressure Regulator
For applications that require high flow capacity
The Type 700 is designed for applications that require high flow
capacity and accurate process control. A poppet valve
balanced by a rolling diaphragm insures a constant output
pressure even during wide supply pressure variations. Stability
of regulated pressure is maintained under varying flow
conditions through the use of an aspirator tube which adjusts
the air supply in accordance with the flow velocity.

•High Flow Capacity
S
Allows flows up to 80 scfm (2,264 Nl/min)
•Sensitive
Senses output pressure deviations to within
1/8 inch water column pressure
•Stable Output
Dampening action of aspirator tube makes this regulator
insensitive to changes in flow
•On-line Maintenance
Can be serviced without removal from air line
