Type 70 - T70 High Flow Air Pressure Regulator
The Type 70 Regulator is specifically
designed for applications that require
substantial flow capacity and accurate
pressure controls. Flows of 80 SCFM
(2250 LPM) can be attained.
Downstream pressure can be set
within 0.25 in. (6.3mm) of water
column and is accurately maintained
under varying flow conditions with the
help of an aspirator tube which adjusts
the air supply in accordance with the
flow velocity. A balanced supply valve,
utilizing a rolling diaphragm, makes the
regulator virtually immune to changes
in supply pressure.
The Type 70 has a
rugged precision
die cast aluminum
housing, and is pressure-tested and chromatetreated for internal corrosion resistance.
The regulator housing is finished with vinyl
paint which resists scratching, weathering
and other physical abuse.
Features:
- High Flow Capacity – Up to 80 SCFM (2266 LPM)
- Responds Quickly to Minute Changes in Downstream Pressure
- Dampening Action of Aspirator Tube Maintains Downstream Pressure
- Honking & Buzzing Eliminated By Action of Integral Baffle and Aspirator Tube
- Stack-up Construction Can Be Disassembled & Serviced without Removal from Air Line
- Optional Versions Include: Non-Relieving, Corrosive Resistant Epoxy Finish, Tapped Vent, Mounting Brackets, Pressure Gauge, Low Bleed, Check Valve
- Large Flow Actuation
- High-flow Louvers
- Rollers and Winders
- High-flow Control Loops
- Calibration Loops
- Any OEM or Industrial Pressure Regulator Application Where a High Degree of Accuracy is Required
