CS – Plate Valve
The robust all-rounder for low to medium pressure applications
Proven design with customized features
The CS – Plate Valve is a plate type valve for low to medium pressure applications. Thanks to its non-metallic valve plate made of impact-resistant polymer, the CS – Plate Valve is a robust all-rounder for a wide range of applications, such as in Chemical, Petrochemical, Technical Gases and hydrogen production by electrolyzers. The optionally available high-performance polymer material HP developed by HOERBIGER also enables the CS – Plate Valve to be used in cryogenic applications such as LNG boil-off. Widely designed flow channels and conically milled seats and guards offer high tolerance against clogging. Tribological optimization for lubrication-free operation and hydrogen-compatible materials provide safe operation in H2 compression systems.
Thanks to the simple but robust design with only one moving sealing element, CS – Plate Valves ensure easy and cost-effective maintenance and high durability.
