Product Specifications
Additional Information
Flange Insert valves are designed to fit between two mating ANSI flanges. The "Spring Housing", designated by the "A" dimension (Check "A" dimension for clearance with pipe ID. Generally "A" dimension is designed for use in schedule 40 pipe for class 150 & 300 valves (F1). Order class 600 (F6) valves for schedule 80 pipe.), is designed to be inserted into the upstream pipe, thereby helping to center it in the pipe. Therefore, there must be clearance between the spring housing and the pipe or flange. Generally speaking, the FIV Class 150 and 300 valves (F1) are designed for standard schedule pipe with Class 150 or 300 flanges, and the FIV Class 600 (F6) valves are designed for schedule 80 pipe with Class 150, 300 or 600 flanges.The Flange Insert valve can also be used as a low pressure relief valve or vacuum breaker by using the desired spring settings. Many valves in this series can be supplied with B16.34 certification.
