Hunter PLD-AVR 1/2" Air/Vacuum Relief Valve (Boxed)

The Hunter PLD-AVR 1/2" Air/Vacuum Relief Valve delivers reliable air release and vacuum protection for micro‑irrigation systems. Designed for installation at high points or line ends, the AVR discharges trapped air during start‑up and admits air during shut‑down to prevent water hammer, pipe collapse, and related system damage. UV‑protected, corrosion‑resistant materials provide long outdoor service life for exposed installations.

• 1/2" male thread fits standard PLD and micro‑irrigation fittings.
• Releases air pockets without premature closure and ensures leak‑free closure after release.
• Operating pressure up to 80 PSI (5.5 bar / 550 kPa) for typical micro‑irrigation systems.
• Compact, low‑profile design (approx. 1 in. height) for easy placement at system high points.
• UV‑protected, corrosion‑resistant construction for durability in outdoor environments.
• Manufacturer two‑year limited warranty; contact distributor for availability and ordering.

Ideal for both commercial and residential drip or micro‑irrigation lines, the PLD‑AVR helps maintain system performance and reduces maintenance by preventing vacuum collapse and water hammer. Refer to the product spec sheet for full dimensions, UPC, and installation notes.
