XP, CP - Profiled Plate Valves
For your process or natural gas application
Conventional valve designs have outlived their purpose when it comes to increasing the efficiency of compressors. Real increases in compressor efficiency can only be achieved through innovative designs. The compressor valve is the heart of the compressor, and the power regulator for overall compressor efficiency. To optimize reliability and saving energies, you need a technologically advanced valve that can do both. HOERBIGER’s XP and CP Profiled Plate Valve series combine all the properties to meet these requirements: PowerPEEK® plates with extreme efficiency and excellent flow characteristics for high compressor uptime. Further, you can drastically decrease the electric power and fuel consumption and reduce the related CO emissions when increasing the service life and up to 50% the efficiency in parallel. But not only that. The valves are also designed for applications in the field of green hydrogen, synthetic fuels, Bio gas and hydrogen transport as well as LNG boil off.
The best valves in efficiency without sacrificing reliability


High efficiency and fewer losses
PowerPEEK® and the unique design of profiled valve plates create a valve with extreme efficiency and excellent flow characteristics. This automatically improves the valve's reliability and durability. The construction of a finer-meshed ring section increases the effective flow area and hence the efficiency of the valve. The aerodynamic “rings” produce a lower pressure drop than plate valves, giving small amounts of liquid and debris the ability to pass. PowerPEEK® plates also offer an optimized distribution of reinforcing fibers and therefore wear less in operation. This leads to an increase in MTBF and MTBM, leading to less losses from unplanned maintenance.
Benefits at a glance
- Profiled plate design
- Spring savers prevent coil to guard contact
- Injection molded high-performance PowerPEEK® and finer-meshed ring section
- Industry benchmark in efficiency: 30 - 50% higher effective flow area than conventional valves. Superior efficiency even at low lift.
- Tribological optimization
- Optimum fibre orientation and high flexural strength. 4-6 time higher impact resistance than standard PEEK.
- Aerodynamic flow path
- Anti-stiction design: Waveshape profiled guard and tapered seat
