Parker Hannifin DirectAir 4 Series Manual Air Control Valve

This Parker Directair 4 Series (3-way, 2-position) manual air control valve allows operators to control the airflow to pneumatic systems and equipment. These valves are used to operate single-acting cylinders. A "maintained" electrical signal shifts the valve. When the signal is removed the valve returns to its normal position. Valves may be externally piloted or converted to normally open. These valves are used to operate single-acting cylinders. A "momentary" electrical signal applied to one of the solenoids shifts the valve. The valve remains in this position until a "momentary" signal is applied to the other solenoid.
