Product Description
Danfoss HPBV (003H6006) — self-acting high-pressure by-pass valve, 32 mm, PN 16, for heating and district-heating circuits. The HPBV is a self-acting differential-pressure relief (by-pass) valve. It stays closed until the differential pressure across it exceeds the spring setting, then opens to bypass excess flow — protecting the circuit and maintaining a minimum flow through the pump when consumer valves close. Adjustable opening (differential) pressure 0.5 – 2.5 bar. OEM P/N 003H6006, EAN 5702428567237. Technical data quoted verbatim from store.danfoss.com (code 003H6006).

Compatibility & Fitment
Danfoss HPBV for 32 mm heating circuits requiring differential-pressure relief / pump by-pass, PN 16. Set the opening pressure within 0.5 – 2.5 bar above the system's normal differential pressure so the valve stays shut in normal operation and opens only on pressure rise. Confirm the connection size (32 mm) and PN 16 against the pipework. Genuine Danfoss part — specify order code 003H6006.
