Description
Model G Riser Check Valve – 6107030000 – 3″ (80mm) – 3RC
The Model G Riser Check Valve is designed for use in wet pipe fire protection systems. Its grooved end connections facilitate easy installation with listed or approved mechanical couplings, ensuring a quick and secure setup. The valve is equipped with a spring-loaded clapper that minimizes water hammer, maintaining smooth and reliable operation within the fire protection system. Its lightweight and compact design allow for versatile installation in both horizontal and vertical configurations.
This valve is also designed with factory-tapped drain outlets and gage ports on both sides, providing flexibility during installation. Its low friction loss body design ensures optimal performance by reducing energy loss. The Model G Riser Check Valve is a cost-effective solution, especially in installations that do not use mechanical alarms but require electric alarms when paired with water flow detectors.
