Engineered for sloped landscapes and elevation changes, the Hunter HCV Check Valve (HC50F50F) is a top-adjustable drain check that eliminates low-head drainage and prevents puddling at low points. Install it between a riser and sprinkler head to hold water in the line until pressure drops below the check setting—keeping turf and hardscape clear while conserving water. Stops low-head drainage and surface puddling to reduce runoff and wasted water on slopes and terraces. Top-access, adjustable check height lets installers set or change the setting quickly through the sprinkler body without removing the valve. Adjustable range compensates for elevation differences up to 11 m (32 ft), making it suitable for steep grades and terraced sites. Constructed to Schedule 80 specifications for improved pressure resistance and long-lasting durability in demanding irrigation systems. Compact 76.20 mm length with 1/2 in. female inlet and 1/2 in. female outlet threads; lightweight, corrosion-resistant construction; made in Mexico. Simple to install and compatible with common pop-up sprinklers and risers, the HC50F50F is ideal for residential, commercial, and municipal irrigation projects where preventing puddles and protecting walkways matters. See the downloadable installation and adjustment guide for detailed steps and pressure-loss charts.
