        Description:
        The back pressure regulator is a high-flow, high-precision
 pneumatic relief valve with adjustable setpoint. It provides
 protection against overpressure in the downstream section of
 pneumatic systems. A convoluted diaphragm provides the
 sensitivity for venting to the atmosphere in response to the
 slightest upstream change.
 
 Media: compressed air or non-corrosive gases
 
 Overpressure: max. 21 bar up to pressure range of 14 bar, max. 35 bar beyond
 
 Adjustment: by handwheel with locknut
 
 Gauge_port: G1/4 on both sides of the body, screw plugs supplied
 
 Mounting_position: any
 
 Temperature_range:
 0 °C to 90 °C / 32 °F to 194 °F,
 for appropriately conditioned compressed air down to -40 °C / -40 °F
 
 Body: aluminium die-cast
 Elastomer: NBR/Buna-N, optionally FKM
