GA-135T-00-32

Operating principle of GA-135T-00-32

Hydraulic pressure acts on a sensing element that operates electrical contacts at the calibrated pickup and release values. The resulting circuit starts or stops warning and emergency-pump functions according to the aircraft wiring diagram. 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 system, in the pressure-monitoring circuit used to command warning and emergency pumping. The exact aircraft, connector and installation position require its maintenance documentation. 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 GA-135T-00-32 for ordering

Preserve the full GA-135T-00-32 suffix and verify pickup and release settings. GA-135T-00-32 is a pressure switch, not a flow-control valve, despite being grouped with hydraulic control units. Other related products are listed in the valves category. An enquiry should state the complete designation, execution, condition, delivery set and required supporting documents.
