Hansen HA2B-11 is a compact back-pressure regulator from Hansen’s HA2A/HA2B family, designed for refrigeration duty to maintain a defined back pressure in small refrigerant lines. It features a 5/32" connection and a regulation range of 0–150 psi (Range A), with a gauge port for pressure monitoring. The regulator body is typically a ductile iron construction, while steel variants exist for HA2BQ and HA2BT family members. Used in compact refrigeration applications where precise pressure control is required, the HA2B-11 provides reliable, steady back pressure in demanding environments.
