Hunter IBV101GFS 1" Brass Valve with Filter Sentry Constructed from solid brass to provide years of trouble-free operation in any water condition, the Hunter IBV is a valve created for the fiercest conditions found on a commercial site. Featuring a brass body and bonnet—built to handle up to 220 PSI—the IBV also boasts a sturdy stainless steel flow control stem. The IBV was designed from the ground up to incorporate many of the industry-leading features found in Hunter valves including the solenoid and ICV diaphragm. Add in a pair of options and provide the IBV with an even higher degree of dependable performance: the Accu-Sync pressure regulator maintains constant downstream pressure and the Filter Sentry™ system keeps the valve free of debris found in reclaimed water or ponds. Built to withstand the rigors of high-pressure situations, the IBV is the commercial-grade valve solution for years of reliable operation.
