Model G Riser Check Valve – 6107040000 – 4″ (100mm) – 4RC
The Model G Riser Check Valve is specifically designed for use in wet pipe fire protection systems. It offers easy installation with grooved end connections that are compatible with listed or approved mechanical couplings, ensuring a secure and efficient setup. The valve’s spring-loaded clapper helps minimize water hammer, providing smooth and reliable operation. With a compact, lightweight design, it is suitable for both vertical and horizontal installations.
This valve comes with factory-tapped drain outlets and gage ports on both sides, enhancing flexibility for installation and system monitoring. The streamlined body design reduces friction loss, resulting in improved overall system efficiency. This Model G Riser Check Valve is ideal for installations that don’t require a mechanical alarm but can work with water flow detectors for electric alarms.
