Description
GA-133-100-4K Hydraulic thermal relief valve
GA-133-100-4K is a hydraulic thermal relief valve that protects a closed hydraulic-system volume against excessive pressure generated by thermal expansion of the working fluid. The unit is an independent functional component of its onboard system. Selection should be based on the complete designation, normal state, controlled medium and installation diagram rather than appearance alone.

Operating principle of GA-133-100-4K
The unit provides an automatic relief path when pressure in an isolated hydraulic section reaches the calibrated value. It works without a separate crew command and returns to its closed condition after pressure is relieved. Serviceability depends on the moving element, seat, seals and electrical section where fitted. Contamination, reversed connections or an incorrect supply can alter the intended response.
Role in the aircraft system
Hydraulic system; exact aircraft and installation point must be confirmed from the applicable parts catalogue and hydraulic diagram. The valve works with pipelines, a pressure source, downstream equipment and the control circuit of the applicable system. These items are functionally related but must not be described as interchangeable components.
Installation and maintenance checks
Before installation, verify the nameplate, ports, connector, internal cleanliness and seal condition. Pressure, voltage, polarity, operating temperature and the prescribed functional test must come from the passport and maintenance documentation. Adjustment without approved instructions is not permitted.
Identifying GA-133-100-4K for ordering
The complete 4K suffix is essential. Its calibration or interfaces may differ from GA-133-100-1K, so the two versions are related but not automatically interchangeable. Other related products are listed in the valves category. An enquiry should state the complete designation, execution, condition, delivery set and required supporting documents.
