Meet the Air & Vacuum Valve Series 35 | Cla-Val: Superior Protection for Water Systems

Discover the Air & Vacuum Valve Series 35 | Cla-Val, designed to keep your water lines safe and running smoothly. This advanced valve is your system’s front line of defense against destructive air pockets and dangerous vacuum conditions. Whether for municipal water distribution or irrigation, it’s the smart choice for reliable, worry-free operation.

Features and Benefits: Air & Vacuum Valve Series 35 | Cla-Val

  • Automatic Air Release: Never worry about trapped air again. The Series 35 automatically expels unwanted air, preventing blockages that slow water flow and can damage pipes.
  • Vacuum Protection: Sudden drops in pressure can pull pipes inward or cause contaminated water to enter the system. This valve quickly lets air in when needed, shielding your pipes from collapse and keeping your water clean.
  • Rugged Construction: Engineered with high-quality materials, the Series 35 stands up to the toughest environments. It resists corrosion and is built to deliver years of dependable service.
  • Low Maintenance: A simple yet effective design means less time spent on upkeep. Easy access and fewer moving parts help ensure trouble-free performance.
  • Versatile Applications: Perfect for a wide range of water systems, including pipelines, tanks, and pumps. Installation is straightforward—you don’t need advanced expertise to set it up.

The Air & Vacuum Valve Series 35 | Cla-Val uses a compact float mechanism to sense changing air pressures. As soon as air builds up or a vacuum forms, it reacts instantly, letting air escape or enter as needed. This lightning-fast response helps avoid pipe bursts, water hammer, and energy losses, saving you costly repairs and downtime.

With the Air & Vacuum Valve Series 35 | Cla-Val, you gain both safety and peace of mind. It fits new or existing systems seamlessly and runs silently in the background—so you can focus on what matters most, knowing your water supply is protected.

  • Prevents pipe damage and costly leaks
  • Maintains steady water flow
  • Protects against contaminated water entering the system
  • Suitable for both above and below ground installs
  • Trusted Cla-Val quality and performance

Upgrade your water system’s defense with the Air & Vacuum Valve Series 35 | Cla-Val—the simple solution for a safer, smoother water supply.

Datasheet and documents

Description

The Cla-Val Series 35 Air and Vacuum Valve is designed to perform two separate functions. First, it will allow large quantities of air to be exhausted from the pipeline as it is being filled with water. When this air has been vented completely, water will enter the valve causing the float to seal tightly against the seat to prevent water flow. Second, if the line is being drained, either intentionally or as a result of pipeline breakage, the valve responds to the loss in pressure and opens. This allows air to re-enter the pipeline and prevents a potentially damaging vacuum from developing.

Series 35 Air and Vacuum Valves should be installed at high points or at grade changes within the pipeline. Mount the unit in the vertical on top of the pipeline with isolation valve below each valve in the event servicing is required. A vault with adequate venting and drainage should also be provided.
