Description
Model G Riser Check Valve – 6107080000 – 8″ (200mm) – 8RC
The Model G Riser Check Valve is designed for reliable and efficient operation in wet pipe fire protection systems. Featuring grooved end connections, it ensures quick and easy installation using approved mechanical couplings. The valve incorporates a spring-loaded clapper to minimize water hammer, enhancing system performance by preventing abrupt pressure fluctuations. With its compact design, this valve is suitable for both horizontal and vertical installations.
Factory-tapped drain outlets and gage ports on both sides provide flexibility in installation and system monitoring. The valve’s low friction loss design minimizes energy loss, improving the overall efficiency of the fire protection system. The Model G Riser Check Valve is a cost-effective solution for systems without mechanical alarms, especially when combined with water flow detectors for electric alarms.
