brass construction: made from quality 591 brass with an integrally forged body for strength and antiburst protection. The forging technology creates a valve body that resists aging and maintains stability even under demanding conditions. Builtin pressure gauge: features a clear, easytoread gauge for realtime monitoring of your water pressure system. Quickly visualize current pressure readings and make adjustments within the 16 bar range to protect your plumbing fixtures and appliances from excessive pressure damage. Efficient filtration system: equipped with an integrated filter screen that effectively blocks particle impurities from entering your water system, extending the valve's lifespan and protecting downstream fixtures. The marked water flow direction and simple design insure straightforward installation and minimal maintenance requirements. Precise pressure control: professionally calibrated with a factory setting of 3 bar and adjustable between 16 bar, this regulator maintains consistent downstream pressure regardless of inlet pressure fluctuations. Handles maximum working pressure of 10 bar and operates efficiently in temperatures from 20C to 110C for reliable performance. Use scenario: in homes with variable incoming water pressure, install and set around the factory 3 bar to protect faucets, valves, and appliances; use the gauge to monitor and adjust as needed. Use scenario: protect sensitive appliances such as dishwashers and washing machines by maintaining a stable downstream pressure and filtering out impurities that could cause clogs or wear. Use scenario: retrofit or installation where a single device provides both pressure regulation and filtration, ensuring consistent downstream pressure and cleaner water across the system.
