High Purity and Ultra High Purity Check Valve
High-Capacity Sensitive Check Valves-CF Series
High-Capacity Sensitive Check Valves, also known as exhaust check valves, feature minimal cracking pressure and high capacity.
These valves are typically installed on the exhaust side of a vacuum pump to prevent air from entering the system during pump shutdowns or malfunctions.
Features
◎ 316 SS body, equipped with FKM O-ring
◎ Minimal cracking pressure
◎ Large orifice and high capacity
◎ KF Vacuum Flange Port

Ultra High Purity High-Capacity Check Valves-CB Series
CB Series Ultra High Purity High-Capacity 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
◎ Connection tube in customized length available
◎ Low cracking pressure and high sensitivity
◎ High flow capacity with a flow coefficient (Cv) of up to 165.5

Anti-Siphon Back Pressure Check Valves CSV Series
Chemical pumps are commonly used in the industries like oil and gas, chemical, pulp & paper, etc. The function is to inject a certain amount of chemicals into the system to improve production or prevent corrosion. Usually, anti-siphon valve, back pressure valve and check valve are installed downstream to ensure the chemical pump works properly.
FITOK CSV series anti-siphon back pressure check valves integrate three different functions into one, help you to save space, improve installation efficiency and reduce maintenance:
Anti-Siphon function:
reduce unwanted siphoning due to wellhead or pipeline condition change.
Back pressure function consistent:
provide back pressure to keep the output flow from chemical pump
Non-Return function:
prevent fluids flowing back to the chemical pump.
Features
◎ Integrate three different functions into one, fewer number of connections improve the system reliability
◎ Small size, light weight and low installation space requirements, easy for installation and operation
◎ Inline adjustment of cracking pressure with broad pressure range
