Suntec Oil Safety Valve

Oil under pressure or vacuum is supplied to the inlet of the PRV valve. Vacuum is required at the outlet of the PRV valve to open it and allow oil to flow. When a burner starts, the pump will supply the vacuum necessary to open the valve. Any leak in the system which prevents vacuum from being exerted on the outlet port of the valve will prevent oil from flowing.|Maximum protection against line leaks and tank siphoning|Prevents high pressure damage in gravity feed or boost pump installations|Suitable for no. 2, no. 1 fuel oil or kerosene|Mounts in any position|UL approved
