Solenoid Valves - Ametek 5920 UHP User Manual

Solenoid Valves

Two (2) solenoid valves are attached to a solenoid bracket located on the top of
the MFM mounting bracket. These valves are labeled SAM (Figures 4-1, 4-2, and
4-5) for the sample solenoid valve assembly (AMETEK Part No. 591016901) and
REF for the reference solenoid valve assembly (AMETEK Part No. 591092901).
They are connected by wire to the board at the location marked on the side of
the valve wire connector. A third reference solenoid valve (AMETEK Part No.
592094901) is located on the other side of the mounting plate and is attached
to the Reference Purifier. It is mounted on the reference solenoid bracket and
labeled SAM 1.
