The voltages can be adjusted by without special tools Turn counterclockwise to decrease pressure The presets pressure value of the pressure reducing within the safe pressure range of 2-2.5KG, which can be used directly The can greatly increase the water pressure at low water pressure, while maintaining the stability of water at high-water pressure The pressure reducing connect to the 3-way ball-valve of the water purifier inlet, or the water purifier inlet pipe installed in series It can be installed in most water purifiers, faucets and other water equipment It materials, and can be used for long-time The water pressure relief regulator can the harm of water-hammer, increase the pressure of the systems, and reduce the leakage fault when the water flows quickly
