Description
The linear valve electric actuators provide with thrust ranges from 250 to 2,000 kgf (551~4,409 lbs). All models are equipped with modulating controllers and suitable for globe valves, gate valves and linear travel devices. It can be applied to HVAC and industrial use, especially for the steam and high temperature employments.
