Oil Sampler Valve With Flange

Although the transformer oil valve on the power transformer oil tank are small, they are crucial for the safe operation of the entire equipment. The oil drain valve, sampling valve, Flange Oil Sampler Valve, and oil filling and draining seat - these "invisible heroes", especially those with double-layer sealing technology, are truly reliable choices. Featuring a robust flanged connection structure, flanged oil sampler valve provides enhanced sealing performance and reliable mechanical stability for medium and high-voltage transformer systems. During daily maintenance, do not overlook the inspection and maintenance of them - regular cleaning, confirming that the sealing rings are not aged and the threads are not damaged, is the first line of defense against oil leakage.

Once a Flange Oil Sampler Valve has been installed, how does one proceed to extract the transformer oil?

Let Wenzhou Best engineer team tell you:

For small transformers, samples can be drawn from the drain valve located at the bottom; this method yields a representative oil sample that captures various impurities and moisture present within the transformer. Large transformers are typically equipped with dedicated sampling valves, generally positioned in the lower-to-mid section of the transformer tank's side to facilitate convenient sample collection. First, open the drain valve to discharge a small quantity of transformer oil (approximately 1–2 liters) for the purpose of flushing the sampling tube and collection bottle. This step is critical, as it clears away any impurities that may be present within the sampling apparatus, thereby ensuring the purity of the collected oil sample. Finally, connect one end of the sampling tube to the drain valve and insert the other end into the bottom of the collection bottle.
