Hunter HCV Check Valve, 1/2 in. Female x 1/2 in. Female

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.
