Hendrickson - Model PRC4500 Series -Preset Pressure Regulator

The new PRC4500 Series Preset Pressure Regulator is a 1/2” low flow pressure regulator with a built in check valve. It will prevent line drainage from causing unwanted erosion and water puddles. This regulator works by remaining closed with no flow until the check valve opens. After opening, the sprinkler or watering system will operate at the selected preset pressure. Upon system shut down, the flow of water will stop when the inlet pressure drops below the preset pressure.
