Description
UG-135 Electrohydraulic brake-release valve
UG-135 is a electrohydraulic brake-release valve that connects the wheel-brake release circuit to hydraulic pressure when commanded by the automatic braking system. The unit is an independent functional component of the applicable onboard system. Selection should be based on the complete designation, working medium, setting and installation diagram rather than appearance alone.
Operating principle of UG-135
An electrical command shifts the hydraulic distributor and supplies pressure to the brake-release line. Removing the command returns the valve to its normal state so the braking circuit can resume its prescribed operation. Reliable operation depends on clean working fluid, the moving element, seat, springs and seals. Contamination, reversed connections or an unsuitable pressure can prevent the intended response.
Role in the aircraft system
Wheel-brake automatic release circuit in documented aircraft installations. A Yak-40 technical description identifies UG-135 together with UE24/1 in the wheel release function; exact configuration must follow the aircraft manual. The valve works with pipelines, a pressure source, downstream equipment and the control elements of its circuit. These products are functionally related but must not be described as interchangeable merely because they operate in the same system.
Installation and maintenance checks
Before installation, verify the nameplate, ports, flow direction, internal cleanliness and seal condition. Working pressure, temperature, fluid and the prescribed functional test must come from the passport and maintenance documentation. Adjustment without approved instructions is not permitted. Incoming-inspection results should remain with the product records.
Identifying UG-135 for ordering
Confirm whether the documentation calls for UG-135, UE24/1 or a specific suffix. Related designations can share a system role without being automatically interchangeable. Other related products are listed in the valves category. An enquiry should state the complete designation, execution, condition, delivery set and required supporting documents.
