Xylem-Hoffman Specialty 400280 Pressure Pilot 20-175 PSI SPS-175

The Xylem-Hoffman Specialty 400280 SPS-175 Pressure Pilot 20-175 is a pressure control device for HVAC systems, particularly boilers and pump systems. It works by monitoring the system pressure and adjusting a bypass valve accordingly. If the pressure drops below a certain level, the pilot opens the valve, allowing more fluid to flow and increasing the pressure. If the pressure rises too high, the pilot closes the valve, reducing flow and preventing pressure buildup. The Xylem-Hoffman Specialty 400280 SPS-175 Pressure Pilot 20-175 automatic regulation contributes to optimal system performance, prevents equipment damage from overpressure, and ensures efficient operation. By maintaining stable pressure, the pilot ensures the system's efficiency and longevity.
