MICO Inc. has announced the release of the S12 Series Electrohydraulic Brake Valve (EBV). In large, spring-applied, hydraulic release brake applications, it has been able to replace two standard electrohydraulic brake valves operating in parallel or an EBV and relay valve. The brake valve handles high flows without the complexity and orifices associated with pilot-operated fluid power valves. Instead of using a pilot valve, with its associated high leakage and contamination sensitivity, a high force solenoid is combined with a precision fit spool and housing to maximize contaminant resistance and minimize leakage. The cross-hole metering set-up of the standard MICO electrohydraulic brake valve is also used in the S12 Series EBV. The S12 incorporates a longer spool to incorporate a second flow path – which runs parallel to the standard path – giving the new series a higher flow capacity from brake to tank. These features make the valve suitable for spring-applied, hydraulic release brake applications requiring high flows such as those found on vehicles with large displacement brakes. All MICO EBVs are developed specifically for full power brake systems.
