The PS1E series valve is an internal air piloted stacking style with plug-in coils. Available valve functions are 3/2, and 5/2 single and double solenoid.
Each valve is individually wired with a separate conductor.
Surge suppressors with an indicating LED are available and are mounted between the coil and the valve body.
Internal pilot operation means the supply pressure on the #1 port is directed to the end of the valve where the solenoid operator, when actuated, allows the supply pressure to pass, which is then applied to the piston to shift the spool.
