# ANSI/IEEE Solenoid-valve NC auxiliary contact form Canonical URL: https://eloragrid.ai/symbols/ansi-solenoid-valve-nc-auxiliary-contact Publisher: Elora Grid Updated: 2026-10-28 Lookup label: HSV22 Drawing use: Schematic Reference families: IEEE / ANSI, Manufacturer ## Symbol convention Convention: IEEE / ANSI Form: Solenoid Valve Auxiliary Normally Closed Contact Autodesk IEEE Symbol Preview: Solenoids, block HSV22. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier. Related representation: [Solenoid-valve NC auxiliary contact](https://eloragrid.ai/symbols/iec-solenoid-valve-nc-auxiliary-contact) IEEE-library form of solenoid-valve nc auxiliary contact: this form identifies a normally-closed auxiliary contact associated with a solenoid valve. ## In plain English ### What does ANSI/IEEE Solenoid-valve NC auxiliary contact form mean? This reference locates solenoid-valve nc auxiliary contact in Autodesk's IEEE-oriented solenoids family. This form identifies a normally-closed auxiliary contact associated with a solenoid valve. The public library uses HSV22 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number. ### A simple example Read the operating mechanism and the contact reference state together. Cross-reference every associated contact to the same device and show which movement, signal or reset changes its condition; the symbol alone does not establish the complete switching sequence. ### What the drawings help you do State the reference condition used to describe the contact as normally closed. A contact normal state and the process valve normal state are separate descriptions. State the reference condition used to describe the contact as normally closed. A contact normal state and the process valve normal state are separate descriptions. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted. ### This particular reference IEEE-library form of solenoid-valve nc auxiliary contact: this form identifies a normally-closed auxiliary contact associated with a solenoid valve. A contact normal state and the process valve normal state are separate descriptions. ### Terms - Normally open / normally closed: The contact state in the normal condition defined for the drawing. - Coil: A wound conductor that can produce a magnetic field when energised. - Signal: Electrical information passed between devices, rather than necessarily the main power supply.
