The 8550 Series Pressure Reducing Station (PRS) provides the regulation required for optimal drinking valve performance in an automated watering system for laboratory animals. It is designed to provide filtered, potable, chlorinated, acidified or purified water at the recommended operating pressure of 3-4 psi (21-28 kPa, 0.21-0.28 bar). The PRS panel assembly contains high and low stainless steel pressure regulators and can switch from low to high pressure for flushing. Flushing is performed automatically to enhance the water quality by bringing fresh water into the piping. In addition, the pressure station monitors pressure and flow in the watering system.
