Description
UG34/2 Hydraulic pressure switch
UG34/2 is a hydraulic pressure switch that changes an electrical contact state when hydraulic pressure reaches the calibrated switching condition. 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 UG34/2
Hydraulic pressure acts on a sensing member opposed by a calibrated spring. At the switching threshold the mechanism changes the electrical contacts and provides a discrete signal to the aircraft indication or control circuit. 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
Aircraft hydraulic and wheel-brake monitoring circuits. An-24, An-26 and An-30 maintenance documentation identifies UG34/2 hydraulic switches in the braking hydraulic system. 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 UG34/2 for ordering
Keep the slash in UG34/2 and verify the switching pressure, contact diagram, connector and thread. UG34, UG34/1 and other suffixes are separate calibrated executions. Other related products are listed in the valves category. An enquiry should state the complete designation, execution, condition, delivery set and required supporting documents.
