Product Description

Senninger - Model PR-HF FPT x FPT Regulator - High Flow

Senninger’s High Flow Pressure Regulators are ideal for installations requiring higher flows, including solid set sprinklers, low volume manifolds and mechanical-move irrigation systems. Each regulator maintains a constant preset outlet pressure based on its flow / inlet pressure. Note that with no flow through the regulator, the inlet and outlet pressures will be the same.

All Senninger pressure regulators are constructed of durable high-impact

engineering-grade thermoplastics with a high quality stainless steel compression spring and securing screws. This durable construction coupled

with their outstanding design and precision parts make them suitable for a variety of different applications.

  • Caution: Always install pressure regulators downstream from all shut-off valves.
  • Be sure to install pressure regulators in the proper direction. The arrow on the upper housing shows the direction of the flow and should always point downstream toward emitters.
Special note: This pressure reducer is not designed to operate under static (constant) pressure. It must be installed after any valves or timers to operate correctly. Using this item under static pressure will eventually weaken the internal spring and cause the regulator to fail.
