Description

The GESTRA CB 24S, CB 26, and CB 26A models are wafer-type swing check valves (with a flap design) in accordance with EN 558-1, series 96.
Their short face-to-face dimensions and low weight provide advantages in terms of transport, storage, and installation.

The CB 24S model is designed for installation between flanges that comply with the following standards:

  • EN 1092 PN 6 / PN 10 / PN 16

  • ASME B16.1 Class 125 FF and ASME B16.5 Class 150 RF
    This model is equipped as standard with a soft NBR sealing.

The CB 26 and CB 26A models are designed for installation between flanges that comply with the following standards:

  • EN 1092 PN 6 / 10 / 16 / 25 / 40

  • ASME B16.1 Class 125 FF and ASME B16.5 Class 150 / 300 RF
    These models are equipped as standard with a soft EPDM sealing.

All models can be installed in horizontal or vertical pipelines.
When installing in vertical pipes, the flow direction must be from bottom to top.

Applications of GESTRA CB24S – CB26 – CB26A Series Swing Type Check Valves

GESTRA CB24S – CB26 – CB26A Series Swing Type Check Valves

GESTRA CB24S, CB26, and CB26A check valves are used in various industrial and building systems to prevent backflow. Typical application areas include:

  • Heating, Ventilation, and Air Conditioning (HVAC) Systems
    (Heating circuits, circulation loops, heat distribution centers)

  • Steam and Condensate Systems
    (Heat exchangers, steam boilers, condensate return lines)

  • Water Supply and Wastewater Systems
    (Pumping stations, distribution lines, filtration units)

  • Industrial Piping Systems
    (Chemical, petrochemical, food and beverage, pharmaceutical industries)

  • Compressed Air and Gas Systems
    (Compressor units, pneumatic pipelines)

  • Cooling and Process Fluid Circuits
    (Closed-loop cooling systems, chillers, cooling towers)

Thanks to their compact design and universal compatibility, these valves can be easily integrated into existing pipelines and provide reliable protection against reverse flow.
