Built for Performance
The Model 3530 isn't your average regulator. It features massive 1/2" inlet and outlet ports, allowing for significantly higher flow rates than standard station regulators. This means you won't experience pressure starvation when you open up the valve on high-consumption equipment. With a delivery pressure range of 0-500 PSI, it provides the versatility to handle everything from standard welding pressures to high-pressure testing or heavy cutting applications.

Durability You Can Count On
Harris has engineered this unit to last. The 2-3/4" stainless steel diaphragm offers superior service life compared to rubber alternatives and ensures that your gas stream remains pure and free from diaphragm outgassing. The internal components are protected by a sintered filter that traps pipe scale and debris before it can damage the seat, ensuring reliable shut-off and regulation year after year. The brass body is rugged and corrosion-resistant, ready to withstand the daily grind of the shop floor.

Safety and Precision
Accurate adjustments are made easy with the ergonomic adjusting knob and the clear, easy-to-read 2-1/2" brass gauge. Safety is built-in with a self-reseating internal relief valve, giving you peace of mind while you work. Upgrade your pipeline drops with the Harris Model 3530 and experience the difference that professional-grade flow control makes in your productivity.
