Netafim DG-10 Combination Air Valves (PN10)

Lightweight, High-Performance Air Management for Irrigation & Water Systems

The Netafim DG-10 is a dual-function combination air valve engineered to release trapped air and prevent vacuum formation in pipelines, ensuring stable and efficient system performance. Designed for use in low to medium pressure irrigation, water supply, and filtration networks, it combines both an automatic air release and air/vacuum relief function into one compact, corrosion-resistant unit.

While similar in function to the D-040, the DG-10 is rated to 10 bar and constructed with lightweight materials suitable for plastic and low-mass pipelines.

FEATURES

• Dual Functionality: Combines automatic air release (during pressurized flow) with air/vacuum relief (during filling or draining) in one valve.
• Prevents System Damage: Eliminates trapped air pockets and vacuum conditions that can cause pressure loss, water hammer, metering errors, or even pipe collapse.
• Large Orifice for High Discharge Rates: Features a larger-than-standard air release orifice, allowing for faster discharge and minimizing debris blockage risk.
• Rolling Seal Mechanism: More reliable under pressure fluctuations than traditional float seals—ensures consistent performance across a wide operating range.
• Durable & Corrosion Resistant: Constructed from high-strength plastic and non-corrosive internal materials, ideal for use with treated water and agricultural chemicals.
• Lightweight Design: Suitable for plastic and lightweight piping systems, with threaded drain outlet for removing residual fluids.
