Electric Air Valve Actuator

To create a fail safe design consider a spring return actuated valve that uses air to help operate a valve in one direction and springs to help operate in the reverse direction.

Electric air valve actuator. Ingersoll rand air control valves are designed to be shifted by means of an electrical solenoid. They are rotary and linear. The rod or carriage moves the load. There are two main types of actuators one for each of the two main types of valves that require them.

As the screw turns it moves a piston which is connected to the rod or carriage. Performance varies depending on materials used. In the most common type of pneumatic actuator the diaphragm actuator air is pumped into a hollow casing where the resulting pressure acts on a flexible rubber diaphragm to deflect it from its original position. A valve actuator is a mechanical device that uses a power source to operate a valve.

The compressed air is then able to create motion or to do work by attaching devices to the actuator rod or. Use in pneumatic valve applications such as packaging food processing material handling woodworking and assembly. Solving customer esd challenges in an aging plant. Dependable eim electric actuators improve delayed coker.

The air actuator converts the energy stored in compressed air into mechanical energy. Spring return actuators have air or liquid supplied to only one side of the piston and the energy to. Designed to turn heavy loads these rotary air actuators have rack and pinion gears that provide high torque output. Electric actuators consist of a ball acme or roller screw connected via a coupler to an electric motor.

Pneumatic actuators use air or another gas pressure as the primary power source to produce motion which in turn controls the valve. They feature solenoid spring actuators and offer rugged construction with excellent flow. Commonly used motors for electric actuators include steppers and servos. This configuration uses pneumatic or hydraulic pressure of the air or liquid energy to open and close the valve.

When coupled with a solenoid pneumatic actuators also can produce torque to move cylinders or enough torque to trigger small electric devices. Double acting actuators have air or liquid supplied to both sides of the piston with one side at higher pressure which achieves the movement required to actuate the valve. This power source can be electric pneumatic compressed air or hydraulic the flow of oil. Electric actuators cost effective positioning on multi cyclone furnaces secondary air shutoff dampers.
