Parker’s CB and CBF Series Check Valves are designed for uni-directional flow control of fluids and gases. The unique floating ball valve design handles demanding services in a variety of industries. The CB/CBF Series are specifically designed to reduce check valve maintenance and performance requirements on dual fuel turbines. General poppet design check valves do not handle these high demand applications very well. Specific issues of a poppet check valve include, but are not limited to seat leakage, coking, high repair and maintenance costs. All of these issues directly affect turbine efficiency, impacting operating costs.

The advanced seat materials of the CB/CBF Series Check Valves are particularly suited for higher temperature applications requiring high integrity leak rates and re-sealing capabilities.

Markets:
• Power
• Chemical
• Oil & Gas

Features/benefits:
• Rugged and reliable floating ball valve seat design optimizes sealing characteristics while minimizing effects of coking.
• Optional hard PTFE coated ball cage resists poppet “stick” commonly experienced with fuel oil coking.
• Fully field serviceable with Parker rebuild kits. Replace seats in minutes without special tools.
• Advanced reinforced PTFE copolymer seat materials designed by Parker for demanding applications such as air purge and fuel oil.
• Integral “last chance” filter option for seat and nozzle protection.
• Connects directly to Parker metal hoses to assist in even further reduce turbine downtime during repairs.

Applications:
• Dual Fuel Turbines
• Fuel Systems
• High Temperature System Protection
• Injection Systems
