A pressure-reducing valve (PRV) helps control and stabilize water pressure in a plumbing system. Water coming from the main supply can often be too high, which may damage pipes, taps, heaters, and household appliances. A PRV automatically reduces this incoming pressure to a safe, consistent level. It works by using an internal spring and diaphragm that adjust the flow based on the pressure level—when pressure rises, the valve tightens; when pressure drops, it opens. This ensures steady water pressure throughout the building and prevents leaks or system stress.
In the UAE, reliable PRVs are essential for both homes and commercial setups. Al Zerwa Trading supplies high-quality pressure-reducing valves known for durability, accuracy, and smooth performance in local water conditions.
