⦿ Valves for Water Works system
Air Release Valves for water systems, and Combination Air/Vacuum Valves protect your piping system by automatically eliminating air pockets and preventing vacuum formations from building-up in the pipeline during filling or draining operations. Excessive air in a system can dramatically reduce capacity and increase power demand as pumps work harder to maintain desired flow.
In extreme cases, excessive air or vacuum formation can cause line breaks. The best way to protect your piping system from these negative conditions is to utilize air valves in the locations most likely to experience air or vacuum build-up:high-points in the pipeline, adjacent to pumps, in long pipe runs and at deep well installations.
Air Valves perform two important functions in a piping system. They maintain system design efficiency and provide system protection. System efficiency is maintained by venting air via the air valves from the system that can restrict flow and increase pumping costs.
Protection is provided by exhausting and admitting air through the air valves during system operations including start-up, shutdown, and critical conditions such as power failures or line breaks. The exhausting and admitting of air during these conditions will reduce the potential for destructive surges and water hammer normally associated with uncontrolled air or a vacuum condition within the piping system.
Air/Vacuum Valves, also called large orifice valves, are designed to exhaust large quantities of air .....
Combination Air/Vacuum Valve
Combination air valves are designed to perform the same function as air/vacuum valves. But, in addition, they will automatically release small air pockets of air from the pipeline while under pressure, like an air release valve.
Air Release Valve
Air Release Valves, also called small orifice valves, are designed to automatically release small pockets of accumulated air from a pipeline while the system operates under pressure exceeding atmospheric pressure.
Air/Vacuum Valve with Surge Check
This valve is an integral development product of air/vacuum valves combined with water hammer prevention products inside. Water hammer prevent function is performed at 10 divided ...
Combination Air/Vacuum Valve with Surge Check
Combination air valves with surge check are designed to perform the same function as air/vacuum valves with surge check. But, in addition, they will automatically release small air pockets of air from the pipeline while under pressure, like an air release valve.
Vacuum Relief Valve
For critical applications where vacuum protection is a must or water column separation is predicted, a vacuum breaker is used. The Vacuum Breaker is mounted at critical pipeline high points, penstocks, or tanks and allows for rapid inflow of atmospheric air to reduce vacuum conditions in piping systems.
Combination Vacuum Relief Valve
Combination Vacuum Valves are designed to perform the same function as Vacuum Relief valves. But, in addition, they will automatically release small air pockets of air from the pipeline while under pressure, like an air release valve.
