RD-14-00-1

RD-14-00-1 Adjustable safety valve

RD-14-00-1 is a adjustable safety valve that maintains a selected hydraulic pressure by bypassing excess AMG-10 fluid into the return line. It is a functional part of the applicable hydraulic or pneumatic system and should be selected by exact designation and installation documentation rather than by appearance alone.

Operating function of RD-14-00-1

The servo-operated valve remains closed below its adjusted opening pressure. Once the threshold is reached, the pilot and main stages open a bypass path; the unit closes again after pressure falls by the documented differential. Reliable operation depends on clean working media, serviceable seals, correctly connected lines and a calibrated configuration that matches the technical documentation.

Role in the aircraft system

The valve works with AMG-10 and is rated for pressure up to 30 MPa. Its opening-pressure adjustment range is 2–30 MPa. Existing technical data also records operation at 100 L/min and a closing-pressure relationship of P₀ minus 15 kgf/cm². Connected units form one operating circuit, but each performs a separate task and must not be presented as interchangeable merely because it is installed in the same system.

Installation and maintenance checks

RD-14-00-1 may be installed in compatible hydraulic systems and test equipment where adjustable overpressure protection is required. A specific aircraft application was not independently established in the open documentation reviewed for this update. Maintenance checks normally cover connection tightness, body condition, contamination and compliance with the specified test limits. Any calibration or adjustment must follow the product passport or approved repair documentation.

Identifying RD-14-00-1 for ordering

Verify the complete suffix, calibrated opening pressure, working fluid, connection geometry and test record. RD-14-00-1 and RD-14-00-4 belong to the same family but must not be considered interchangeable without configuration data. Other related items are listed in the valves category. An enquiry should identify the required execution, condition, delivery set and supporting documentation.

Verified configuration and traceability

The recorded technical data identifies RD-14-00-1 as a adjustable servo-operated safety valve. Confirmed function: Maintaining selected hydraulic pressure by bypassing excess fluid to return. Recorded mass: Not more than 1.3 kg. These values belong to the stated execution and should be checked against the passport of the individual unit before installation.

The documented system context is Hydraulic pressure and return lines according to system documentation. For a safety valve, calibrated opening pressure, reseating pressure and the approved adjustment procedure are critical. Changing the setting without the passport procedure can alter the protective function of the entire circuit. Incoming inspection compares the complete marking, body execution, ports, threads, seals and indicated flow direction. Final verification is based on Product passport and bench-test record required for confirming the setting. The four related products shown on the page provide navigation to functionally close units and do not state that those products are interchangeable.

Search and quotation records should preserve the exact RD-14-00-1 lettering and must not merge it with adjacent family suffixes. Forms without spaces or hyphens may be used as search variants, but they do not prove a different approved execution. An enquiry should also identify the installation system, required condition, delivery set and supporting documents. This information separates the requested unit from visually similar valves and preserves sourcing traceability.
