GA-215

GA-215 Hydraulic flow proportioner

GA-215 is a hydraulic flow proportioner that meters a controlled AMG-10 flow for a compatible actuator or regulating circuit. 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 GA-215

The internal metering element creates a controlled flow section and limits the delivered quantity to the specified rate. Exact direction, pressure compensation and connected mechanism must be confirmed from the system 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 and helicopter hydraulic systems. Public catalogues identify GA-215 as a proportioner, but the exact aircraft and actuator position require the illustrated parts catalogue. 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-215 for ordering

Confirm designation GA-215, 2.5 L/min rated flow, pressure class, port orientation and direction of metering. GA-57/1U is a reversible proportioner and not an automatic substitute. Other related products are listed in the valves category. An enquiry should state the complete designation, execution, condition, delivery set and required supporting documents.
