DIG’s Heavy Duty Preset Pressure Regulators offer exceptional performance of pressure control with constant lower downstream pressure regardless of incoming pressure fluctuations. Used to reduce and regulate the water pressure entering a drip irrigation or micro sprinkler system, this range of pressure regulators can lower the incoming pressure from as high as 120 PSI to a downstream pressure of 20 to 40 PSI at a flow range of .5 to 12 gallons per minute. Utilizing very few moving parts, the pressure regulator’s sophisticated diaphragm design regulates itself in reaction to the overall system back pressure. It is also engineered with industrial-strength, heavy duty plastic for operation under extreme conditions.

Features & Benefits
