Netafim Anti-Drain Valves for Overhead Irrigation

Ensure precise, drip-free irrigation with Netafim’s Anti-Drain Check Valves – the essential component for any upside-down misting or micro-sprinkler system. Designed to prevent unwanted drainage from distribution pipes after shutdown, these valves keep your system primed for pulse irrigation while protecting delicate plants from water damage.

Each valve features a durable push-fit Male x Female connection and operates based on a preset pressure threshold, closing fully to eliminate residual dripping. Built from acid-resistant materials, these valves are ideal for systems using fertigation or periodic chemical cleaning.
