You really need to study exactly what its for.
If its just a check valve, then its not governed by heat. This means it may only be a one-way valve and might be to prevent airlock, cavitation or return oil drainage so that the pumps always primed.
If there is no other passage that returns the oil to the engine by-passing the cooler, then its not what you need.
A proper oil cooler control system will have a by-pass of the cooler so that on a cold start or in cold weather the thicker oil is not forced through the oil cooler until it has thinned out some by heat.
