Rain Bird DASASVF075 Professional Anti-Siphon Valve with Flow Control - 3/4 in. Female x Female

Overview

Rain Bird's DASASVF075 is a professional-grade anti-siphon valve designed for above-ground irrigation zones. It features a 3/4" female threaded inlet and outlet, a top-mounted flow control knob, and a reverse-flow design that helps limit water loss if the diaphragm encounters a fault. This valve works with standard 24-volt AC irrigation timers and controllers, making zone-by-zone management simple and predictable.

What sets this valve apart is its combination of durable construction and intelligent water management. The Buna-N diaphragm resists wear in challenging water conditions, while the built-in filter helps protect the mechanism from debris. An energy-efficient, low-power encapsulated solenoid with a captured plunger adds to long-term reliability, and the rugged housing with stainless steel screws is built for outdoor use.
