Description
Model G Riser Check Valve – 6107076000 – 76mm (3″) – 76RC – Red
The Model G Riser Check Valve is designed for efficient wet pipe fire protection systems. Featuring grooved end connections, it allows for quick and easy installation using listed or approved mechanical couplings. The valve is equipped with a spring-loaded clapper that minimizes water hammer, ensuring smooth and reliable operation. Its compact and lightweight design makes it suitable for both horizontal and vertical installations.
This valve comes with factory-tapped drain outlets and gage ports on both sides, providing installation flexibility. The low friction loss body design ensures that the fire protection system runs efficiently by reducing energy loss. It is also a cost-effective solution in systems that don’t use mechanical alarms, especially when paired with water flow detectors for electric alarms.
