Pressure reducing valve for water purifier inlet. It connects to the 3-way ball-valve on the purifier inlet or inline on the inlet pipe. It is suitable for installation in most water purifiers, faucets and other water equipment. Benefits - Improves low-pressure performance: greatly increases water pressure when supply is low, while preserving stability at higher pressure. - Tool-free adjustment: pressure can be adjusted without special tools. Turn counterclockwise to decrease pressure. The preset pressure value is within the safe range of 2-2.5 KG and can be used directly. - Durable construction: made from long-lasting materials for extended use. Specifications and compatibility - Inlet connection for water purifiers and inline piping; compatible with most purifiers, faucets and other water equipment. - Preset safe pressure: 2-2.5 KG. Applications - Home use where municipal water pressure is low, to boost purifier and faucet performance. - Environments with fluctuating water pressure, to maintain a steady output. - Retrofit or new installations across various water purification and dispensing equipment.
