Introduction
FITOK CB Series Low Pressure High Flow Check Valves are engineered for low pressure and high flow bulk gas distribution applications. These valves are suitable for use with inert gases as well as most toxic gases, effectively preventing undesired reverse flow within the high purity system.
Features
- Metal-to-metal seal between valve body and bonnet
- Packless design eliminates particle contamination from packing wear
- Integrated purge port on valve body for easy purging
- Low cracking pressure and high sensitivity
- High flow capacity with a flow coefficient (Cv) of up to 165.5
- Connection tube in customized length available
