The function of directional control valves is to control the direction of flow in a pneumatic circuit. These valves can regulate the airflow being capable of stopping, passing, and changing the direction of airflow. These three functions usually operate in combination with each other.
Directional control valves have multiple ports with the number dependent on the valve type. All these valves have an inlet and an outlet port while many also have an exhaust port. The 21 series is offered in 2/2, 3/2, and 4/2 valve functions with a port size range of ¼” to 1-1/2” in both NPT and G threads.
The poppet construction of the 21 Series enables high-flow, positive sealing, self-cleaning, and a strong dirt tolerance that delivers a long-life. This valve series is available in both solenoid and air pilot controlled options. Solenoids are offered in several AC and DC voltages.
Fluorocarbon and Buna-N seal options enable these valves to be used in a wide range of lower or higher temperature applications.
