Giuliani-anello ST1B12 Burner Accessory
Technical specs, application notes, replacement checks, and related model references.
Product Overview
The Giuliani Anello (Watts Water Technologies) ST1B12 is a precision gas pressure regulator (governor) designed to provide unparalleled stability and control of downstream gas pressure in industrial and commercial heating applications. Equipped with a highly sensitive compensating diaphragm, it dynamically nullifies inlet pressure fluctuations, ensuring a constant and accurate fuel supply to the burner head. Its robust die-cast aluminum construction and fail-safe design guarantee long-term reliability and compliance with EN 88 standards.
