Top Notch Actuator and Valve Parts for Your HVAC Unit

The actuator and valve parts for your HVAC unit are very important to the functionality of your unit. The outside unit of your heat pump consists primarily of the condenser coil, a compressor and a fan. Most of the hard-working equipment is housed within the inside unit.

Any time your heat pump requires repair or maintenance, the technician will connect pressure gauges to make sure there is the correct amount of coolant. Liquid coolant will be added through a port on the outside unit if needed. Leaks are relatively rare, but they do occur. Occasionally coolant, also called refrigerant, will need to be drained and refilled. van điều khiển khí nén

Actuators and Parts

An actuator, by definition, is a mechanical device for moving or controlling a mechanism or system. Operated by some source of energy, it converts energy into motion. Consider the wheel and axle for example. Rotating the axle causes the wheel to move; and as a direct result, causing whatever is attached to the wheel to move as well.

Energy created by hydraulic fluid, electric current or pneumatic pressure may be converted into motion using an actuator. The actuator in your HVAC unit is likely controlled by electric current. They are used most commonly for inflow-control valves, pumps, motors, relays, switches and positioning drives.

The two most common types of actuator are hydraulic and electro-servo. A hydraulic actuator forces hydraulic fluid through cylinders or motors and is controlled by control valves. Hydraulic machinery produces very high amounts of power and makes use of a variety of actuators in the process.

A pneumatic actuator compresses air to use as its source of energy. They contain a piston, cylinder and valves. The piston is protected by the diaphragm, which keeps the compressed air in the upper portion of the cylinder. Air pressure pushes the diaphragm down, which moves the piston down as well.

Control Valves and Parts

Control valves are used to control the flow, pressure, temperature, or liquid level of various mechanisms. The valve may be partially opened or closed in order to maintain proper flow, pressure or temperature, as it does with your HVAC system. Control valves are generally opened or closed by using an electrical, hydraulic or pneumatic control system.
