Designed to protect compressor reservoirs and other unheated pressure containers from over-pressurization by evacuating air when maximum pressure is reached. The pressure is preset at the factory to an unchangeable pressure setting, in which case the safety valve releases the air in the system into the atmosphere. Superior, corrosion-resistant quality. Optimum air exhaust rate. High air flow rate. Canadian registration number: OG-06391.2 Valve manufactured in accordance with the safety valve standards of the National Board of Boiler and Pressure Vessel Inspectors, section ASME VIII.
