Oil ValveUse for Automotive

The Oil valve, thermoelement built-in, senses the rise in oil temperature and controls the flow of oil by closing and opening of the oil passage through the lift(movement of piston) of thermoelement. Mainly mounted in the flow circuit of engine oil(lubricant).
Oil temperature is influenced by driving conditions. For example, oil temperature exceeds 130℃ in a hot open air, high speed driving,uphill driving etc,then,sometimes deterioration of oil and malfunction of engine occurs.The engine oil cooler is installed in some case to prevent this, and direct installation to the engine tends to cause the break of oil cooler under high oil pressure due to lower oil temperature.
Therefore, in order to avoid this break a by-pass circuit is added to the oil passage and oil flows through the by-pass when oil temperature stays lower, while as it becomes higher, oil begins to flow to the oil cooler, control of which is made by the oil value built-in the by-pass circuit.

Service temperature:-40℃~+130℃
