Valve Actuator Products From Clark Solutions
Clark Solutions offers direct coupled two-position spring return electric valve actuators for control of building HVAC dampers or valves. These valve actuator products are used for the control of valves or dampers and are available in a variety of models and torque ranges. The EN44C2 and EN88C2 direct coupled 24 VAC non-spring return rotary electronic actuators are designed for tri-state (floating) control or two-position control (with external relay) of valves and dampers. They may be used in applications requiring up to 44 in-lb (5 N-m) of torque or 88 in-lb (10 N-m) of torque. Model RE electric/electronic actuators are ideal for demanding valve applications and air damper control. These valve actuators are available with torque ratings from 150 in-lbs to 10,200 in-lbs. Model RE Valve Actuators incorporate current limiting as a means of protecting the actuator for over-torque situations and do not depend on torque switches or thermal overload sensing. The current limiting feature activates a light (and an optional relay) upon exceeding the current limit set, to allow for easy field diagnostics.
