Product Detail: |
|
The Marsh Bellofram Type 70 air pressure regulator is expressly designed for applications requiring substantial flow capacity of up to 80 SCFM (2250 LPM) and accurate pressure controls. Downstream pressure can be set within 0.25 in. (6.3mm) of water column and is accurately maintained under varying conditions via an aspirator tube which adjusts air supply in accordance with flow velocity. A balanced supply valve, utilizing a patented Bellofram rolling diaphragm design, makes the regulator virtually immune to changes in supply pressure, and offers millions of cycles.
The Type 70 features a rugged, precision die-cast aluminum housing, and is pressure-tested and chromate-treated for internal corrosion resistance. The regulator housing is finished with vinyl paint which resists scratching, weathering and other physical abuse
Applications
· 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

Non-Relieving: Used in applications where it is desirable to relieve pressure downstream of the regulator, for some constant flow applications, and where the gas flowing through the regulator must not escape at the regulator. Non-relieving regulators should not be used for low or no flow applications.
Corrosive Resistant Epoxy Finish: An epoxy paint applied to the body of the regulator exterior surfaces to provide increased corrosion resistance.
Tapped Vent: Allows installation of plumbing to capture exhaust air.
Mounting Bracket: Steel (dichromate finish) bracket for side mounting.
Pressure Gauge: Dual scale 2 in. (50.8 mm) gauges. Ranges include 0-30 psig
(0-200 kPa), 0-60 psig (0-400 kPa), 0-100 psig (0-700 kPa) and 0-160 psig (0-1100 kPa). When specified with regulator, the correct range will be supplied.
Tamper Resistant Cover: An aluminum tubular cover placed over a slotted head adjusting screw and screwed onto the bonnet of the regulator with a wrench. Prevents ordinary hand adjustments.
Low Bleed: Reduces steady-state air consumption by approximately 50%.
Check Valve: Allows quick dumping of output line pressure through the supply air line when the supply is shut down. |
