Description Specifications Literature Description The Marsh Bellofram Type 10 Air Pressure Regulator is designed to control output pressure with accuracy of 0.1% and high-repeatability, with very low sensitivity to changes in supply pressure, ambient temperature and flow.The highly rugged design of the Type 10 includes unique features such as high start-up stability, which eliminates the need for regulated start pressure readjustment after long downtimes with automatic return to output setting at start-up; incorporation of a high-gain pneumatic servo amplifier for regulated pressure, ranging from dead end to 20 cubic meters per hour (12 SCFM), held constant over substantial flow changes; incorporation of an extra-large capacity integral relief valve, for exhaust flow when regulated pressure is reset to a lower value, with automatic high downstream relief under dead end conditions; and incorporation of a high-performance servo-operated control mechanism in the regulator, for added pressure stability. The entire measuring element, including pilot valve, is fabricated from heat-treated stainless steel to eliminate hysteresis or permanent deformation under all working conditions. An integral relief valve provides for exhaust flow whenever the regulated pressure is reset to a lower value. In addition, the available Type 10 motorized configuration allows for easy integration into open- or closed-loop process control systems and programmable controllers.Features:Highly Accurate Pressure Regulation to 0.1%Start-up Stability, Allowing Regulated Pressure to Return to Output SettingAutomatic High Downstream Relief CapacityHigh-gain Pneumatic Servo Amplifier Regulates Wide Fluctuations in FlowEspecially Good Performance from Dead End to 12 SCFMLocking CapabilityTemperature StabilityUnits may be installed in any position and panel mounted or supported by inline plumbingAvailable variations to meet particular requirements, such as high-relief, low-range and motorized configurationsApplications:Pipe and Vessel Air Pressure MonitoringIndustrial ProcessesHVAC, Remote Pressure Control Ventilation SystemsElectro-pneumatic ControlInspection ProceduresControl and Analysis InstrumentationMedical Equipment ActuationGas MixingValve Operation and Gate ActuationPositioned SignalingCalibration StandsAir GaugingCylinder LoadingForce Balance HoistsDisc and Shoe Air BrakingClamp UnitsWeb TensioningRoll LoadingPress Units State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
