Senninger Pressure Regulating Landscape Valves 20mm

Features Maintains a constant preset outlet pressure based on the flows/inlet pressures below (Note: With no flow through the regulator, the inlet and outlet pressures will be the same) 100% water-tested for accuracy (no adjustments ever needed) Very low hysteresis and friction losses Large flow path resists plugging Patented tamper-resistant design No external metal parts for excellent corrosion resistance Flows: 0.5 - 7 gpm (114 - 1589.8 L/hr) Always install downstream from all shut off valves 20mm female NPT inlet 20mm male NPT outlet Use Plastic Fittings Only  Overview Senninger introduced the first high-quality inline pressure regulator to the agricultural industry in 1966. Over the years, these black and white regulators have become known for their reliable strength and durability, and their ability to preserve an applicator’s flow, distribution uniformity, and the overall effectiveness of an irrigation system. With a wide range of pressures and flows, Senninger’s line of pressure regulators can meet a variety of installation needs ranging from demanding mechanized sprinkler installations to nursery and greenhouse installations. They are recommended if there is a 10% pressure and/or a 5% flow variation. Each is built using high-impact engineering grade thermoplastics and is 100% water-tested at our facilities. Senninger’s PRLG maintains a constant preset outlet pressure with varying inlet pressures. This alleviates pressure differences will cause an applicator’s area of coverage to change. The PRLG is ideal for installations requiring lower flows like low volume and sprinkler irrigation systems connected to hose bibb faucets or other lawn and landscape applications.
