The UTC (Gas thread) check valves allow the full flow of oil in one direction and stop the flow in the opposite direction. The applications where these valves can be used are many, agricultural machinery or industrial installations.
Used in all those circumstances where you need the full flow in one direction and the block in the opposite direction. The external body is made of high resistance steel and protected externally from oxidation with a zinc plated.
It is possible to request a surface treatment in zinc/nickel to increase the resistance to oxidation, in case the valve is poorly protected and exposed to atmospheric agents.
