This brass water pressure reducing maintaining valve with regulator and adjustable relief valve provides reliable downstream pressure control for domestic and commercial water systems. It reduces incoming supply pressure to a safe, stable level while offering built in overpressure relief for added protection. The unit is designed for durability, easy installation and long service life in a variety of piping configurations. Key benefits Protects piping, fixtures and appliances from supply pressures and pressure surges. Maintains a stable downstream pressure despite fluctuations in the incoming supply. Adjustable regulator allows precise setpoint control; integrated relief valve handles overpressure safely. Brass construction offers durability and corrosion resistance in water applications. Wide compatibility with common connection sizes: G1/2, G3/4, G1, and G2 (corresponding to DN15, DN20, DN25, DN32); this listing is DN32 (2 inch) version. Simple inline installation and straightforward maintenance for reliable, ongoing performance. Suitable for a range of water systems, reducing noise, leaks and wear on downstream components. Key attributes Material: Brass Function: Water pressure reducing maintaining valve with regulator and adjustable relief valve Inlet/outlet connections: G 1/2', 3/4', 1', 2' (DN15, DN20, DN25, DN32) Size for this listing: DN32 (2 inch) Adjustment: Adjustable downstream setpoint Safety: Integrated relief valve for overpressure protection Package: 1 piece Applications and use cases Residential main water line: reduces city pressure to a safe, stable level for household plumbing, fixtures and appliances. Heating and boiler feed lines: provides consistent water pressure to boilers or heating systems, improving efficiency and protecting components. Commercial or irrigation systems: maintains steady downstream pressure for drip emitters, valves and equipment, reducing performance variability and wear. Usage tips Verify correct thread type and size for your installation. Use appropriate thread sealant or tape as required. Install on the supply side with flow direction as indicated by the valve body; ensure secure connections to prevent leaks. After installation, adjust the downstream pressure to the desired setpoint, then test for leaks and verify stable performance. Periodically inspect for signs of leakage and verify the set point remains within the required range for your system. Maintenance and care Check for leaks at connections and around the valve body during routine maintenance. Periodically recheck and recalibrate the downstream setpoint if supply conditions change. Ensure access for inspection and future adjustments; the unit if corrosion or damage is observed. Notes This product is designed for water use and should comply with local codes and standards. When selecting sizes, consider DN15/DN20/DN25/DN32 options and corresponding G thread connections to match your system requirements. This description reflects the product's brass construction, pressure reducing and maintaining function, adjustable regulator and builtin relief valve, DN32 sizing, and compatibility with G thread connections and DN sizes as specified.
