Air Release Valve Manufacturer in USA – SVR Global
SVR Global is an Air Release Valve Manufacturer in USA, supplying high-performance valves designed to remove trapped air and gases from pipelines. Our air release valves are built to AWWA C512, API, and ASME standards, ensuring reliable service across critical industries.
Function & Working
Air release valves automatically discharge air pockets that collect at pipeline high points. The float mechanism inside the valve rises and seals as fluid enters, and drops to vent air when pressure builds. This prevents cavitation, maintains hydraulic efficiency, and safeguards pumps and pipelines from pressure surges.
Advantages
- Prevents flow obstruction caused by air locks
- Minimizes water hammer and surge effects
- Increases pumping efficiency and reduces energy costs
- Compact construction with long service life
- Available in single or combination configurations
Types Offered
- Air Release Valve – Vents small air pockets continuously
- Air & Vacuum Valve – Handles large volumes of air during filling/draining
- Combination Air Valve – Merges both functions for full system protection
Industries Served
- Water Distribution & Transmission
- Power Generation
- Marine & Offshore Pipelines
- Oil & Gas Networks
- Wastewater Treatment & Desalination Plants
- Irrigation and Drainage (industrial-grade metallic applications)
