The HDPR-25, DIG’s heavy duty 3/4″ Preset Pressure Regulator, offers exceptional performance of pressure control and consistent preset pressure. Used to reduce and regulate the water pressure entering a drip irrigation or micro sprinkler system, this pressure regulator can lower the incoming pressure from as high as 150 PSI to a downstream pressure of 25 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 extra thick industrial-strength plastic for operation under extreme conditions.

The HDPR-25 Preset Pressure Regulator is a critical part of drip and other irrigation systems when water pressure is higher than the suggested operational pressure recommended for the system. In most installations, water pressure can be between 40 and 100 PSI with some homes even higher. Typically, in homes with high pressure, a heavy duty pressure regulator is installed on the main water supply to lower the pressure entering the house. Drip irrigation systems are designed to work at an even lower pressure than is set for the house, with the optimal pressure for a drip system between 15 and 30 PSI. If a higher pressure is found in a drip system, problems such as drip emitters popping off the drip or micro tubing, higher flow from the drip emitters or micro sprinklers, components blowing out of the drip tubing and micro tubing, and overall shortening of system life can occur. To achieve extended life with high uniformity and lower maintenance, a pressure regulator is highly recommended to maintain optimum system pressure, regardless of any fluctuations in the house system’s pressure.
The point of connection to the water supply can start from an in-line or anti-siphon valve, well, pump or rain barrel combined with gravity feed.
