V tork

VTMR series spring return electric actuator applies spring driven pinion and rack mechanism to generate torque ranges from 50Nm to 300Nm. Under normal power supply condition, actuator is launched by motor driven equipment and spring stores energy in the mean time. When emergency power off , spring releases the energy to drive the actuator and ensures the equipment and device return to safe position (full open or full close). The whole process is sesure and stable to eliminate the burst pipes(hammer-blow effect).

VTM series electric actuator features compact construction, robust structure, light weight as well as large output torque (35NM—4000NM). Worm gearing and vortex rod in high precision provide self - locking function and clutchless manual override design eliminates clutching operation in operation method switch. The series presents the product features guaranteeing a stable and convenient operation satisfying Ex dll ct5 anti-explosive design, IP67 protection level and ISO5211 mounting standard.
