Definition Definition of approved item name (AIN): "VALVE,REGULATING,SYSTEM PRESSURE"

A value designed to automatically maintain within close limits a predetermined pressure within a closed system regardless of the higher fluctuating or constant inlet pressure. The excess pressure is by-passed to the accumulator or reservoir in lieu of passing through the entire system. It is designed primarily for use in refrigeration and air conditioning systems. Excludes valve, regulating, fluid pressure and valve, calibrated flow.

Identification Codes

HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.

PMIC: Precious Metal Indicator Code. A one position code which identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.

ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.

ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.

CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.
