⁄
4" NPT threaded. Output is toward the front, supply is toward the back.
Maximum allowable air supply pressure to the SVI II ESD varies according to actuator, valve size,
and valve type. Refer to the serial plate of the valve to know the specified supply pressure; it must
never be less than the maximum spring pr10 psi.
