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.

    Several aspects factor into choosing the proper concrete dowel drill - Randy Stevens. The concrete paving industry has seen significant changes to dowel drilling equipment over the years. Many years ago only hand-held models existed and when the first hydraulic drills were launched over 30 years ago, these increased production and reduced labour needs. Since that time pneumatic drills, have come to market and these are driven by air compressors, which are common on many worksites while the units also have l

    Curtiss-Wright Industrial division has developed the JC040, a single-axis, proportional rocker that is suitable for arduous applications in specialty off-highway vehicles. The JC040 unit uses non-contacting, sensing technology for long-life integrity of its output signal. The IP67-rated JC040 provides safety functionality through dual outputs, which can be set to positive or a combination of positive and negative ramps and also benefits from independent supply voltages for each of the outputs.
