Dual Plug Valves

Principle of Operation of Dual Plug Valves

Dual Plug Valves are mounted between two oil coolers inside the reservoir tank. The valve is piped to the system inlet and outlet and to inlet and outlet ports on both coolers. During operation only one cooler is in operation and the other cooler is isolated. The valve is rotated to select operation on the desired cooler.
