An air purifier is a device, which removes contaminants from air. It is used to reduce the concentration of airborne contaminants and is useful for people who suffer from allergies and asthma.
4-Way Direct Acting Valves are available on 4-way valves which meters exhaust flow from each working port to exhaust port of valve. The 3-way valves can be configured by mounting valve 180° in opposite direction. These are featured with 12 and 24 Vdc coils rated for mobile voltage operation.
4-Way directional control valve pressurizes and exhausts two ports. The valve body consists of 5 ports. A 4-Way valve has four distinct flow paths within the valve and is commonly used to cause reversible motion of a cylinder or motor. Actuating the valve directs flow through input port 1 to output port 4 as output port 2 exhausts through port 3. In the unactuated position, airflow is directed through input port 1 to output port 2 as output port 4 exhausts through port 5.
