PREETAM® DI Tamper Proof Air Valve
PREETAM® DI Tamper Proof Single Chamber Air Valves
Efficient Air Release & Vacuum Protection
Our Tamper-Proof Single Chamber Air Valves are designed for effective management of air in water pipelines. Whether during pipeline filling, draining, or under pressurized operation, these valves provide reliable air release and vacuum-breaking capability, safeguarding the system from surges, air locking, and pressure drops.
Built from high-quality materials and engineered for long service life, these air valves are ideal for transmission and distribution lines, pumping stations, and elevated sections of piping networks. The compact, tamper-resistant design makes them especially suited for public areas and installations vulnerable to misuse.
KEY FEATURES
- Tamper-Proof Design:Integrated locking cover deters unauthorized access and ensures operational safety in public or exposed installations.
- Body Material: High – grade Ductile Iron (GGG50) for superior tensile strength, pressure handling and impact resistance.
- Coating: Fusion-Bonded Epoxy (FBE) internally and externally with minimum thickness of 250 microns for long-lasting corrosion protection in aggressive soil and water conditions.
- Float Mechanism:Precision-engineered Stainless Steel float ensures responsive air release and vacuum intake without sticking or jamming.
- Sealing System:Reliable EPDM/NBR rubber seat with self-cleaning action ensures leak-tight performance under varying pressure condition.
- Flow Optimized Design:Compact body design with streamlined internal contours enhances flow dynamics and reduces turbulence.
- Installation Orientation:Typically installed in vertical position; threaded or flanged connection options available.
- Wide Size Range:25mm to 200mm
- Hydraulic Tested:100% Pressure tested for body and seat leakage in accordance with international standards.
- Water transmission and distribution mains.
- Pumping Stations
- Elevated pipelines and long rising mains.
- Filter stations and tanks.
- Critical pressure zones and system high points.
- Public utility zones requiring vandal resistance.
