REGO A4500Y8 4″ Excess Flow Valve 500 GPM Closing Flow LP Propane

REGO A4500Y8 4″ Excess Flow Valve – 500 GPM Closing FlowThe REGO A4500Y8 Excess Flow Valve is a heavy-duty safety valve designed for bulk propane storage tanks requiring high-capacity flow with automatic excess flow protection. This valve features a 4-inch threaded inlet and is engineered to close automatically at a 500 GPM closing flow rate, helping protect tanks and piping systems from catastrophic line failures.Designed for mounting in flanged tank connections with internal threads, the A4500Y8 is commonly used in filling, liquid withdrawal, and vapor equalization applications. Its high-flow design minimizes pressure drop, reducing pump inlet cavitation while maintaining reliable excess flow protection.Because the valve is mounted internally, it remains protected from external fire exposure and piping stress, improving system safety and serviceability. REGO’s precision-machined construction ensures long service life in demanding propane environments.Key Benefits:Genuine REGO OEM excess flow valve4″ size with 500 GPM closing flowAutomatic shutoff during excessive flow conditionsDesigned for bulk propane tank applicationsHigh flow capacity with low pressure dropProtected internal tank mounting designBrand new, unused, and ready for installation.
