| FULL NAME | ELECTRIC DRIVEN FAUCET 20 |
DESCRIPTION
The faucet is aimed to use in aircraft fuel systems. The faucet is one unit that consists of electric drive (electric motor, reducer, block of microswitches and connector) and hydraulic module (case with two thermal valves, spherical gate and mechanical position indicator of spherical gate).
