Vacuum / Pressure Relief Valves
View/Print Relief Valve Brochure
The Cary Vacuum and Pressure Relief Valves are designed to protect Ring Compressors from overheating either in a vacuum or pressure ("deadhead") condition. Valves are preset to provide protection for each Ring Compressor. Or, Valves are adjustable to provide down to approximately 65% "deadhead" vacuum or pressure. Valves for Fuji Models VFC300A, VFC400A, VFC500A are 1-1/2" NPT size. Valves for Models VFC600A, VFC700A, and VFC800A are 2" NPT. Valves should be checked periodically to assure proper setting.
