There are a large number of options to choose from. We offer Parker Inline Valves and Solenoid Connectors, 3- and 4-way valve passages, 2- and 3-position valve positions as well as 3 types of offset return: air return, air return/spring assist and spring return. If you have questions about which is the best choice for your application, talk to one of our product experts at 1-877-870-2692.
The right solenoid valves can help with surge suppression and reduce wiring time. How do you choose the best solenoid valves for your applications? Start with the number of valve passages, number of positions and offset return.
Consider the number of valve passages: 2-way, 3-way or 4-way. These numbers refer to directional control through the valve. The number of valve passages is the number of air flow paths designed into the valve.
Next, consider position. Do you need a 2-position valve or a 3-position valve?
A 2-position valve uses an actuator that moves the element that connects the ports. The element is returned back through the offset return method. They may be passing or non-passing — when the actuator is not energized, they either will or will not allow fluid flow.
A 3-position valve has two elements connecting the ports, allowing two positions that control the cylinder’s movement in either direction. The third center position is neutral, allowing a pressure center with the pressure port and cylinder ports open and exhaust blocked, an exhaust center with pressure blocked and exhaust open or a blocked center with all the ports blocked.
Finally, choose between three options for the offset return:
