Hendrickson Bros. is proud to introduce their new PRC4500 – an efficient, US-made pressure regulator with a built-in check valve. This ½" low flow unit is engineered to prevent water erosion and puddles due to unwelcome line drainage.
The PRC4500 is offered with flow rates from 0.5 to 6.0 gpm and is available in three popular pressure ratings – 20, 30 and 40 psi.
The design prevents excess flow and wasted water in two ways. First, its internal check valve stays closed until the appropriate pressure has been attained. Once the target pressure has been reached, the valve opens and the sprinkler or watering system operates normally. When the inlet pressure drops during shutdown, the flow stops – and stays stopped without leaking.
