Adjustable Pressure Regulator DN15

This water pressure regulator is designed for domestic filtration and purification systems. It features a DN15 (1/2 inch) inlet with compatibility for 3/8 inch and 1/4 inch connections via adapters (not included). The unit weighs approximately 0.35 kg and measures 95 mm × 55 mm × 40 mm (L×W×H). Constructed from brass body with stainless steel spring and EPDM sealing components, it ensures durability and resistance to corrosion in cold potable water applications. Its core function is to maintain stable outlet pressure across varying inlet conditions — reducing pressure spikes, mitigating water hammer, and improving low-flow responsiveness. The integrated 3-way ball valve allows direct connection to purifier inlets or inline installation on supply pipes. It ships pre-set to a safe operating pressure of 22.5 psi (1.55 bar), adjustable manually without tools: clockwise rotation increases pressure, counterclockwise decreases it. Ideal for homes with inconsistent municipal supply, under-sink purifiers, point-of-use filtration units, dishwashers, washing machines, and kitchen/bathroom faucets where pressure stabilisation and equipment protection are critical.
