FOR SP3 BOILER OUTLET DAMPER-WHR smd-60/k smd-60/k/f

The series of electric valve actuators adopt combined structure in design.The products and parts of the universality of careful consideration, so that users in the use and maintenance process of the number of spare parts varieties needed to greatly reduce, reduce the cost of maintenance and operation.

Motor adopts high torque, low inertia of single-phase or three-phase special motor, all motors are equipped with overheat protection relays, motor rotor output directly with shaft gear, short response time.

The mechanical reducer adopts planetary gear reducer and turbine worm transmission structure, which has high mechanical efficiency, and mechanical self-locking characteristics, and high reliability.At the same time, the use of long-acting lithium grease can ensure that the actuator does not need to be replaced and maintained in a major repair period, and can be installed and used at any Angle.

MD, SMD, YMD series of electric actuator electric appliances adopt integrated circuit devices, in which the power driving part is the solid state relay of the infinite mechanical contact, the service life is long, without daily maintenance, the number of operation up to 1200 times per hour, especially suitable for high automation rate, the place of frequent action application.
