        Type 70

        產品詳細

        Type 70 High Flow Air Pressure Regulator
        • 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
        • Balanced supply valve minimizes the effect of supply pressure changes
        • Bellofram’s Buna-N & polyester rolling diaphragms are designed to give millions of cycles
        • Honking & buzzing eliminated by action of integral baffle and aspirator tube
        • Stack up construction can be disassembled & serviced without removal from air line
        Product Detail:
        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 chromate-treated for internal corrosion resistance. The regulator housing is finished with vinyl paint which resists scratching, weathering and other physical abuse.

        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.
