DIG's heavy duty, low to medium flow, Preset Pressure Regulator offers exceptional performance in a preset pressure regulation of 25 psi. Used to reduce and control the water pressure entering a drip irrigation or micro sprinkler system, the 25 psi Preset 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 0.5 to 12 GPM. Utilizing very few moving parts, the pressure regulator's sophisticated diaphragm design regulates itself in reaction to the overall system backpressure. The high performance pressure regulator is engineered with extra thick industrial strength plastic for operation under extreme conditions. Color: Blacks.
