MICO, Incorporated introduces its hydraulic-over-air relay valves, designed to convert hydraulic modulated input pressure to a proportional output air pressure.
- Ideal for applications such as controlling air-braked trailer with a hydraulically braked towing vehicle that has an air power source
- Hydraulic vehicle component delivers a given hydraulic input pressure that sends a pilot signal to the relay valve, in order to modulate air brake pressure on the other end
- Single input design provides one hydraulic pilot port to control modulated air braking pressure
- Dual input ports can be set up for different pressure ratios, making the design a good fit for certain steering assist applications
- Tandem input provides redundancy with two independent pilot pressure ports, enabling hydraulic pressure to be applied to either port while keeping pressure ratio the same
- Max. air pressure 150 psi
- Max. hydraulic pressure 2,000 psi
- Can operate from a 3:1 to 21:1 hydraulic-to-air-pressure ratio
