DIG’s direct acting adjustable pressure regulator is designed for an area where accurate and reliable control of line pressure is required. The pressure regulator reduces higher incoming pressure to lower constant downstream pressure regardless of fluctuating or varying upstream pressure. The pressure reading is triggered by a pressure reactive diaphragm, which seeks to reach a balance between hydraulic and spring assembly forces. The adjustable pressure regulator has excellent hydraulic performance capabilities and high mechanical strength and it is available with two reading options of 12 to 35 PSI and 28 to 60 PSI.

The pressure regulator is a critical part of drip and other irrigation systems when water pressure is higher than the suggested operation pressure recommended for the system. In most households the water pressure is between 40 and 100 PSI, with some homes being 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 distribution tubing, high flow damaging the drip emitters or micro sprinklers, components blowing out of the drip tubing and distribution 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 pressure.
The point of connection to the high-pressure water supply can start from an in-line or anti-siphon valve, well or pump.
Note: to read the correct pressure, check the pressure at the end of the line or at the last drip emitter on the line. To adjust the pressure, turn the water off, remove the red cap (protecting the red screw) and turn the screw using a screwdriver, clockwise to reduce pressure or counter clock wise to increase it
