Spring Return actuators for Butterfly valves for airport fuel storage

Spring Return actuators for Butterfly valves

Problem

The mentioned Butterfly valves are going to be installed on Fuel storage tanks at Singapore Airport. The function of these valves is to ensure safety (Shut down valves in order to isolate the Fuel in the tanks) in case of Fire.

Solution

Trutorq Italia in cooperation with our Local partnet Trisome, developed spring return actuators that are operated manually in order to reach valves open position.
The mechanical system of movement transmission is blocked in this position through a link system equipped with fusible elements. These elements in case of Fire release automatically the actuators that drive the valve in close position instantly.
