Sensitive High Flow Check Valves

FITOK CF Series sensitive high flow check valves, also known as exhaust check valves, are designed for vacuum applications that require minimal cracking pressure and high flow capacity. They are typically installed on the exhaust side of vacuum pumps to prevent air from entering the system during pump shutdowns or failures. These valves feature a 316 stainless steel body with an FKM O-ring and KF40 vacuum flange ports, ensuring reliability and durability in industrial processes. They are used in industries such as semiconductors, laboratories, pharmaceuticals, chemicals and vacuum packaging, where maintaining a stable, controlled vacuum is critical for safe and efficient system operation.
