Description
The Johnson Controls VA-7150-1001 Electric Valve Actuator is a Universal actuator used specifically on valves for heating ventilation and air conditioning. Unlike basic switch systems that use toggling for ‘on’ and ‘off’, it uses pulse signals to state how far and in what direction a connected valve should rotate. Epulse commands the motor to move in a specific step, which means that the valve can be positioned to a high degree of accuracy. This makes it possible to control the amount of water or air in the HVAC system as the comfort and efficiency of the system is required.
