Senninger® Pressure Regulators

Senninger® Black and White Pressure Regulators are renowned for their accuracy, and ability to maintain the overall efficiency of any irrigation system.

All Senninger® Presssure Regulators maintain a constant preset outlet pressure with varying inlet pressures, which alleviates pressure differences that can cause an applicator’s area of coverage to change and are available in a range of low, medium and high flow models. All our pressure regulators feature:
• 100% pressure tested, to ensure quality and performance;
• Very low hysteresis and friction loss;
• Can be installed above or below ground;
• Patented tamper-proof design;
• No external metal parts for excellent corrosion resistance;
• Two-year warranty on materials, workmanship and performance.

LOW FLOW REGULATOR —
– Senninger® PRLG (Pressure Regulator Landscape Grade) is ideal for installations requiring lower flows of 114 to 1590 L/Hr.
– Senninger® PRL (Pressure Regulator Low Flow) is ideal for installations requiring lower flows of 114 to 1817 L/hr. Suggested use in solid-set, drip, other low-volume irrigation systems, as well as centre pivot and mechanical move irrigation systems.

MEDIUM FLOW REGULATOR —
– Senninger® PSR™2 is designed to handle flows from 114 to 3407 L/hr. Its patented design makes it ideal for use with surface water.
– Senninger® PMR-MF (Pressure Master Regulator Medium Flow) is ideal for installations requiring mid-range flows of 454 to 4542 L/hr, including solid-set, drip and other low-volume irrigation systems.

HIGH FLOW REGULATOR —
– Senninger® PR-HF (Pressure Regulator High Flow) is ideal for installations requiring higher flows of 2271 to 7268 L/hr, including solid-set sprinkler and low volume manifolds.

LIMIT VALVE —
– Senninger® PRLV (Pressure Regulating Limit Valve) is designed to be used in place of standard pressure regulators to limit static (no flow) water pressure when a shut-off valve is used downstream from the regulation point. When this shut-off valve is closed, the t-stem flow-passage closes and seals on the rubber seat, thus limiting the PRLV outlet pressure to only 68 to 103 kPa above its normal regulating pressure. This helps protect downstream components from potential damage due to high static upstream water pressure.
• Designed to control pressure when there is no water flow;
• Installation before shut-off valve;
• The limit valve limits outlet pressure to only 68 to 103 kPa above its normal regulating pressure;
• 100% pressure tested, to ensure quality and performance;
• Very low hysteresis and friction loss.

The basic function of a pressure regulator is to maintain an irrigation system’s desired performance. They control excessive and varying inlet pressures to a constant outlet pressure. Maintain a more uniform application and preserve overal system efficiency with Senninger® Pressure Regulators.

Irrigation systems are designed to take a predetermined amount of water and apply it uniformly over an area and all sprinklers are designed to operate within a specific range of flows and pressures. However, every irrigation system will experience some sort of pressure fluctuation, which also causes unwanted flow deviations. Pressures fluctuate for several reasons including elevation changes within the irrigated area and pressure loss through pipes and fittings. If pressure fluctuations are controlled, sprinklers will be able to function as designed. This results in even plant growth and quality. Uncontrolled pressure fluctuations can distort sprinkler pattern uniformity and lead to over or under watering issues, as well as misting.

In addition, regulation is imperative to properly meter the application of fertilizers and herbicides through the irrigation system.
