        Type 70BP

        Type 70BP

        產品詳細

        Type 70 High Flow Back Pressure Regulator
        • High flow Capacity - Up to 50 SCFM (1400 LPM)
        • Responds quickly to minute changes in upstream pressure
        • Bellofram’s Buna-N & polyester rolling diaphragms
          are designed to give millions of cycles
        • Stack up construction can be disassembled & serviced without removal from air line
        Product Detail:
        The Type 70 Back Pressure Regulator functions as a high flow, high precision pneumatic relief valve with an adjustable setpoint. The Type 70BP can be used in place of a standard relief valve to improve pressure control while maintaining protection against over pressurization, as in supply pressure lines to instruments and other control devices.

        It is most often used in conjunction with a diaphragm-operated valve and bleed orifice as a compressor controller. Excess compressor pressure is relieved through the regulator to actuate the intake restricting valve. When the regulator is shut off, downstream air escapes through the bleed orifice, allowing the restricting valve to open.

        Corrosive Resistant Epoxy Finish: An epoxy paint applied to the body of the regulator exterior surfaces to provide increased corrosion resistance.
        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.
