Rugged hydraulic over air relay valve

MICO Incorporated has new hydraulic-over-air relay valves designed to convert hydraulic modulated input pressure to a proportional output air pressure. The relay valves are ideal for various applications, such as controlling an air-braked trailer with a hydraulically braked towing vehicle that has an air power source. The system originates with a hydraulic vehicle component, such as a master cylinder or hydraulic control valve, which delivers a given hydraulic input pressure. This input pressure sends a pil

The new MICO hydraulic-over-air relay valves are said to be rugged and able to cope with a wide array of operating values
3450 MICO Incorporated has new hydraulic-over-air relay valves designed to convert hydraulic modulated input pressure to a proportional output air pressure.

The relay valves are ideal for various applications, such as controlling an air-braked trailer with a hydraulically braked towing vehicle that has an air power source. The system originates with a hydraulic vehicle component, such as a master cylinder or hydraulic control valve, which delivers a given hydraulic input pressure. This input pressure sends a pilot signal to the relay valve in order to modulate air brake pressure on the other end. MICO offers three different hydraulicover- air relay valve designs: single, dual and tandem. The single input design provides one hydraulic pilot port to control modulated air braking pressure.

  • Asphalt and bitumen - testing for performance
    February 29, 2012
    The stresses placed on modern asphalt and bitumen means that specialist equipment is essential to make sure performance specifications are met. As road traffic increases at a rapid pace and road safety becomes a priority issue, asphalt is put under increasingly higher stresses. For example, road surfaces are subject to compression, flexural tensions and tangential stresses: internal friction, depending on the aggregates, and the cohesion, guaranteed by bitumen's composition, are the two main properties whic

    The alternatives to diesel fuel as a power source continue to grow as firms move to cut emissions - Mike Woof writes. Only the most myopic could have failed to notice that times are changing in terms of engine technology. In the on-highway automotive sector as well as for the off-highway construction machine segment, manufacturers are looking to lower tailpipe emissions. Similar technologies have been employed in both on-highway and off-highway sectors, although those solutions have been adapted to better

    TransCalm is a stand-alone bolt-down speed hump designed to persuade drivers to comply with the limit in 32kph zones and described as a ‘responsive speed control’ by its manufacturer Mallatite. The TransCalm is constructed from a rubber compound containing a pneumatic cylinder, fitted with a patented valve that operates at a preset safe speed. The valve is open for drivers under normal safe use, allowing the cylinder to deflate to around 45mm, reducing the firmness of the unit. If the safe speed is exceede
