BAV120K20 3/4″ BSPT K Type Kinetic Air Release Valve (PN10)

Product Overview

The BAV120K20 3/4″ K Type Kinetic Air Release Valve is an essential safety component applicable to all kinds of agricultural irrigation and industrial water filtration systems. By managing air dynamics—evacuating massive air quickly during pipeline filling and admitting massive air during draining—it prevents water hammer, maintains system hydraulics, and acts as an efficient vacuum breaker to protect pipelines from negative pressure damage.

Working Principle

Our kinetic air valve functions based on aerodynamic principles and a smart one-piece floating ball design:

• Pipeline Filling (Air Exhaust): When the system starts filling with water, the valve remains fully open, allowing large volumes of trapped air to escape rapidly through the kinetic exhaust hole.
• System Under Pressure (Tight Sealing): As water fills the chamber, the aerodynamic float ball lifts to seal the outlet, preventing water leakage even under low-pressure conditions (from 0.1 bar to 0.3 bar).
• Pipeline Draining (Air Intake / Vacuum Relief): When the pump shuts down or water drains, a negative pressure occurs. The float ball drops instantly, introducing massive air to break the vacuum formation and ensure efficient draining without pipe collapse.

Key Features & Advantages

• Advanced Aerodynamic Design: Engineered with a large orifice allowtop design to maximize air kinetic flow rate without premature blowing shut.
• Reliable Dynamic Sealing: High-quality sealing compound prevents weeping or leakage under ultra-low pressure conditions (0.1 bar to 10 bar working range).
• Robust PP Construction: Built from premium polypropylene (PP) material with corrosion, acid, and alkaline resistance, ensuring stability under intense UV radiation and chemical dosing.
• One-Piece Floating Ball: Simplifies maintenance and prevents floating misalignment or mechanical jamming.
• Compact Multi-Application Fit: Standard 3/4″ BSPT thread easily mounts on filter manifolds, main lines, and field sub-mains.

Typical Applications

• Drip & Sprinkler Irrigation Systems: Placed at high elevation points, ends of lines, and before manifold distributions to exhaust trapped air bubbles.
• Water Filtration Manifolds: Mounted directly onto sand media or disc filter systems (like BSS303 and BBS242 series) to vent air pocket bursts.
• Water Distribution Networks: Protects PVC and PE plastic piping networks from destructive water hammer forces.
