The 903/402 series electric actuators for quarter-turn valves are the combination of 903 and 402 series units. They have good lockability and higher output torque.
Characteristic
903/402 series have good lockability and higher output torque.
They have the same characteristics and controlling
methed as 903 series actuators.
They can meet some special requirement, such
as break off the valve fleetly.
