The P60-4 Watts pressure-reducing valve is compact and high-flow, designed to maintain consistent downstream pressure for general-purpose and OEM water applications. It features 1/4-inch NPT female (FPT) connections, a thermoplastic body, and a factory-set 50 PSI that can be adjusted. Key Specs on the P60-4 Watts Pressure-Reducing Valve, 1/4″ FPT Model: P60-4 Connection: 1/4 inch FPT, 1/4-inch NPT female Factory set pressure: 50 PSI, adjustable Maximum working pressure: 300 PSI (20.7 bar) Construction: thermoplastic body, 300 Series stainless internal metal components Internal elastomers: FDA grade (disc, diaphragm, seals) Service feature: bottom clean-out plug Why This Water Pressure-Reducing Valve Matters Helps protect downstream components by regulating pressure consistently Compact and lightweight for tight installs and equipment builds Designed for accurate flow performance in systems needing steady pressure Suitable for deionized water applications Common Uses for the P60-4 Watts Pressure-Reducing Valve, 1/4″ FPT Under-sink filtration and reverse osmosis feeds that need controlled inlet pressure OEM equipment, beverage, and general water applications that require stable downstream pressure Point-of-use systems where pressure spikes can reduce performance or cause leaks Installation Notes: P60-4 Watts Pressure-Reducing Valve, 1/4″ FPT Confirm inlet pressure is within the maximum working pressure rating Use thread sealant appropriate for potable water on NPT connections After installation, adjust pressure gradually and verify with a gauge if your setup includes one If the flow drops over time, the clean-out plug supports service and maintenance FAQs on Water Pressure-Reducing Valves Q: What does a water pressure-reducing valve do? A: It lowers and stabilizes downstream water pressure so equipment receives a consistent supply, even when inlet pressure fluctuates. Q: What is the connection size on the Watts P60-4? A: It uses 1/4 inch FPT connections, also described as 1/4 inch NPT female. Q: What pressure is it set to out of the box? A: It is factory set at 50 PSI and can be adjusted. Q: What is the maximum pressure rating? A: Maximum working pressure is 300 PSI (20.7 bar). Q: Can it be used for deionized water? A: Yes, it is described as suitable for deionized water applications.
