200P Copper Branch Pressure Reducing Valve
Overview
The 200P brass branch pipe pressure reducing valve is a hydraulic control valve widely used in civil buildings and small industrial systems. Its main function is to stably reduce and maintain the higher upstream inlet pressure to a set, lower downstream outlet pressure. It effectively suppresses the impact of upstream pressure fluctuations or downstream flow changes on the outlet pressure, ensuring that downstream pipelines and equipment operate under safe and stable pressure. Usually made of brass with a compact structure, the valve is specifically designed for installation on pipe branches or equipment inlets, serving as a key device to maintain pressure stability in domestic water supply, fire protection systems, irrigation pipelines, etc.
Features
1.Pressure reducing & stabilizing, reliable performance Built-in precision pressure sensing diaphragm and regulating spring set automatically responds to downstream pressure changes. It quickly adjusts flow area via valve disc linkage for dynamic balance, stabilizing outlet pressure at the preset value to protect downstream pipelines and equipment—even with inlet pressure fluctuations or flow changes.
2. Compact structure, easy installation One-piece brass forging ensures sturdiness and small size. Designed for branch pipe pressure reduction, it features threaded connections (e.g., internal or male-female threads) for direct mounting on pipe branches or equipment frontends. It saves space, ideal for dense indoor pipe layouts.
3. Easy maintenance, intuitive adjustment A clear pressure adjustment mechanism is located on the valve cover. Users or maintenance personnel can easily adjust the spring force and precise outlet pressure by turning the adjusting screw with tools—no valve disassembly required, making daily maintenance and debugging convenient.
4. Built-in filtration, valve core protection Most models have a simple filter screen at the water inlet to trap particulate impurities in pipelines. It prevents scratches on sealing surfaces or channel blockages inside the valve, effectively extending the service life of core components like diaphragms and valve discs.
5. Wide application, durable & cost-effective Brass offers good corrosion resistance, suitable for cold water, hot water and various non-corrosive liquids. With stable performance and economical price, it’s a classic, cost-effective choice for pressure control in building water supply, home water entry, water heaters, air conditioning systems, etc.
