The 1 1/4" Wilkins 375 Reduced Pressure Zone began production in 2004 and is still currently in production. The 375 features a unique plastic insert cartridge that houses both checks and relief valve in a compact design and sets into a bronze body. The checks are inline modular design, with self contained check assemblies. Ideal for situations that require winterization, as the whole cartridge can be removed in freezing conditions. A blowout fitting is also available for ease of system winterization. No special tools are required for servicing.
