Description
RD-14-00-4 Adjustable safety valve
RD-14-00-4 is a adjustable safety valve that controls pressure in a compatible oil-hydraulic system by routing excess working fluid to the drain 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-14-00-4
The pilot stage senses inlet pressure and initiates opening when the adjusted threshold is reached. The main stage then provides the bypass flow needed to limit further pressure rise and returns to the closed position as pressure falls. 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
Existing data for the -4 execution specifies hydraulic oils or other compatible non-aggressive fluids, fluid temperature from −60 to +90 °C and an opening-pressure adjustment range of 20–300 kgf/cm². Exact calibration must be confirmed from the product passport. 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-14-00-4 is documented for hydraulic installations and industrial test equipment. Public sources do not provide a reliable aircraft-type assignment for this exact execution, so no aircraft applicability is claimed without the applicable maintenance record. 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-14-00-4 for ordering
Use the complete RD-14-00-4 designation and verify working-fluid compatibility, pressure setting, ports and test documentation. Family resemblance to RD-14-00-1 is not proof of direct interchangeability. Other related items are listed in the valves category. An enquiry should identify the required execution, condition, delivery set and supporting documentation.
