Parker CB/CBF Series Check Valves – Up to 207 bar and 232°C

Parker CB and CBF Series Check Valves – Reliable Flow Control for Demanding Applications

Parker's CB and CBF Series check valves are engineered for precise, reliable one-way flow control in critical applications such as gas turbines, chemical processing, and oil & gas systems. With their robust floating ball design, these valves ensure tight sealing and minimize leakage, coking, and maintenance—especially critical in high-temperature fuel service.

Key Features:

• CB Series: Shell pressure ratings up to 3000 psi (207 bar) with cracking pressures from 1 to 120 psi
• CBF Series: Integrated filter element (75–500 micron) to protect against contamination – ideal as "last chance" filter in turbine systems
• Material: 316 stainless steel with advanced seat materials (Parkerfill and Parker Carbon)
• Temperature Rating: Up to 450°F (232°C)
• Fully field-serviceable with complete repair kits
• Connection Options: A-LOK®, CPI™, NPT, and SAE

The CB and CBF Series are ideal for applications where leak-tight performance, thermal durability, and serviceability are essential for optimal operation and reduced maintenance costs.
