VK EN
Linear actuators of the VK series are used for sensitive linear adjustment of actuators in heating, ventilation and air-conditioning technology as well as in the industrial sector.
The linear actuators in the V series are available with a maximum force of 1,000 N and a maximum stroke of 20 mm.
The robust design, the metal housing made of a die-cast zinc alloy with protection class IP65 and the very compact design allow the actuators to be used even in difficult ambient conditions and where space is limited.
