VTM series electric actuator features compact size,, robust construction, light weight as well as large output torque (35NM-4000NM). Worm gearing and vortex rod in high precision provide self - locking function and declutchable manual override design eliminates clutching operation in operation method switch. The series offers product features guaranteeing a stable and convenient operation satisfying IP67 protection level and ISO5211 mounting standard.

The VTMR series spring return electric actuator is designed for mechanical fail-safe positioning of valves or dampers upon loss of supply power. The VTMR is for used in environments where reliable automatic closing or opening is required upon loss of power. When powered, the VTMR operates like a normal quarter-turn electric on-off or modulating actuator. Under normal powered conditions, the actuator and spring are held stationary through an electromechanical brake system. When power is lost, the spring is activated and returns the actuator to a predetermined fail-safe position. The optional manual override ensures that operators can manually rotate the valve or damper to a precise position and maintain a set position. Manual release is not required during the ele...

VTML series linear electric actuator is standard with modulating valve control and other linear motion devices applying to HVAC and industrial automation, especially suitable for steam or high temperature working condition. The series offers compact design, light weight, large output thrust, high precision motion and convenient adjustment.
