Continuous Air Release & Vacuum Relief Valve (25mm / 1" BSP)
High-performance kinetic air release and vacuum relief valve protecting drip laterals from pipe collapse and soil suck-back.
Key Engineering Benefits
- Tri-action functionality: air exhaust, pressurized micro-venting, and vacuum break
- Prevents drip emitter clogging caused by soil suction during line shutdown
- Protects against devastating water hammer and pressure surges
- Aerodynamic float design prevents premature valve closure under high air velocity
- Corrosion-resistant UV polymer body with zero metal parts in wet path
