RIV 290 Ambra is a vacuum relief valve designed to protect tanks from excessive vacuum by allowing air intake when negative pressure occurs. It has a 1-1/2" ISO 228/1 (BSPP) threaded inlet and vents to atmosphere under a protective cap. Safety features include a mechanical stop that controls maximum opening, a second stop that prevents loosening from vibration and keeps a minimum calibration of about -0.3 bar (-4 psi), and an obturator design that helps prevent internal parts from falling into the equipment.
Features
