CP - Profiled Plate Valve for natural gas

When less is more: HOERBIGER CP valves.

Real increases in compressor efficiency can only be achieved through innovative, smaller designs – which place high demands on all their components. 

Fewer valves for fewer cylinders, with the same or higher performance: Modern compact compressor designs save energy and money. Conventional valves cannot support new compressor designs effectively.

HOERBIGER developed the CP valve with these requirements in mind

Valves must be reliable, to avoid losing the benefits of higher efficiency. Profiled plate technology offers maximum efficiency, despite minimal lift, and excellent closing properties. Additionally, HOERBIGER created PowerPEEK®, an innovative material that ensures robustness and durability – resulting in longer service life for valves and avoiding unplanned compressor downtime.

CP valves are a prerequisite for greater compressor efficiency and reliability

 Leading the market requires being a step ahead. An innovative compressor design puts you ahead of competitors. CP valves make leadership possible. This is why HOERBIGER is an innovation partner for innovative companies.

PowerPEEK® high-performance valve plate material means high reliability and extended service intervals

With the new design of the HOERBIGER CP valve, the combination of profiled seat and valve plate reduces flow losses and lowers energy consumption. PowerPEEK® and the unique design of profiled valve plates create a valve with extremely high reliability, durability, efficiency and excellent flow characteristics. The construction of a finer-meshed ring section increases the effective flow area and hence the efficiency of the CP valve. The aerodynamic „rings“ produce a lower pressure drop than plate valves and thus have the ability to pass small amounts of liquid and debris. Additionally PowerPEEK® plates offer an optimized distribution of reinforcing fibers and therefore less wear less in operation.
