YSF16 series φ130mm directional oil injection pressure relief valve
The YSF16 series φ130mm directional oil spray pressure relief valve is mainly used for pressure relief in the oil tank of large oil-immersed power transformers, power capacitors, reactors, and other equipment when overpressure occurs. When the pressure drops to the closing pressure value of the pressure relief valve, the pressure relief valve reliably closes, ensuring that the oil tank always maintains positive pressure, effectively preventing external air, moisture, and other impurities from entering the oil tank. The pressure relief valve with a directional oil spray device can direct the released transformer oil outward and guide it to the oil collection pool through an oil guide pipe to prevent oil splashing, meeting fire prevention and environmental protection requirements. The φ130mm pressure relief valve, in addition to having a conventional electrical alarm signal, can also be equipped with a computer electrical alarm signal function, which can achieve dual-channel electrical signal output, and each is independently and separately led out. Users can select according to their needs when ordering products.

Product Introduction
The YSF16 series φ130mm directional oil spray pressure relief valve is mainly used for pressure relief in the oil tank of large oil-immersed power transformers, power capacitors, reactors, and other equipment when overpressure occurs. When the pressure drops to the closing pressure value of the pressure relief valve, the pressure relief valve reliably closes, keeping the oil tank always under positive pressure, effectively preventing external air, moisture, and other impurities from entering the oil tank. The pressure relief valve with a directional oil spray device can direct the released transformer oil outward and guide it to the oil collection pool through an oil guide pipe to prevent oil splashing, meeting fire prevention and environmental protection requirements. The φ130mm pressure relief valve, in addition to the conventional electrical alarm signal, can also be equipped with an electrical alarm signal function for computer use, which can achieve dual-channel electrical signal output, and each is independently and separately led out. Users can select according to their needs when ordering products.
Conditions of Use
2.1 Installation location: On the oil tank cover, on the riser, or on the side wall of the upper part of the oil tank;
2.2 Environmental requirements: -30℃～50℃; Working environment requirements: -30℃～+115℃.
2.3 The sealing value is an important parameter for the transformer's optional pressure relief valve.
（ Note: The sum of the highest normal pressure value that appears when the pressure relief valve is in operation plus 7 kPa should be less than the sealing value of the pressure relief valve).
Model Description
*Note: D- indicates directional oil spray, K- indicates electrical signal, SK (or KK)- indicates dual-channel electrical signal, J- indicates mechanical signal, TH- indicates for humid and hot regions, TA- indicates for dry and hot regions, T- indicates for dry and humid and hot regions, B- indicates with a locking device.
Note: YSF8, YSF10, YSF12, YSF14, and YSF16 are all directional oil spray relief valves.
Example of Marking: YSF16-55/130KKJBTH refers to the 16th design, with a spray nozzle diameter of 130mm, opening pressure of 55kPa, directional oil spray, with mechanical and dual-channel electrical alarm signals, for use in humid and hot regions, and with a locking device.
