DIG’s PRV075, 28 to 60 PSI adjustable pressure regulator (pipe thread) is used to reduce and regulate the incoming pressure of the water entering a drip irrigation or micro sprinkler system to the appropriate operating pressure range of 28 PSI and up. The wide range of adjustable pressures allows for flexibility in operating range for all types of irrigation systems. The pressure regulator has a design that includes a plastic screw used for pressure adjustment, a stainless steel spring and a rolling diaphragm housing assembly, which regulates itself depending on the position of the screw in reaction to the overall system back pressure. The pressure regulator offers exceptional control and provides consistent outlet pressure over a wide range of incoming pressures.

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 micro tubing, high flow damaging 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 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 a gravity feed.
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, clock wise to reduce pressure or counter clock wise to increase it
