Pressure control
August 1st 2008

Hoerbiger-Origa has extended its Airfit Control range of proportional pressure regulators with models that, it says, bring truly dynamic control and precise regulation to applications requiring large, rapidly changing pressure differences, high flow rates, or extremes in input or output pressures.

Combining advanced electronics with twin poppet valve configuration, the new models extend the range into new applications, delivering performance and fast response.

Airfit SRE and CRE cover sizes 0.25 (G1/4) to 2in (G2).The design uses two directional valves for converting electrical pulses to pilot pressure. Forced ventilation of the pilot chamber means there is no permanent air consumption and the quantity of air pressure required during the regulation process is low.

A self-regulating seal between pilot chamber and output prevents the stick-slip phenomenon.
