Check Valves

For critical applications

  • Reliable and fast closure before and during flow reversal
  • Long service life, even in pulsating flows
  • Flawless function at all operating points

It is not possible to eliminate problematic pulsations in process engineering plants downstream of reciprocating compressors as well as in collection and other pipes. In addition, highly fluctuating flow conditions are to be expected downstream of controlled compressors. HOERBIGER check valves offer effective protection.

HOERBIGER check valves comply with all key international standards and guidelines. They operate safely and efficiently in pulsating flows and under abruptly changing conditions. They open and close quickly and reliably even with extremely low flow rates. Pressure losses are minimized by exact tailoring to the application.

The proven design and specialized metallic materials ensure smooth operation - even in highly corrosive applications. The frictionless guided valve plate reduces wear and tear as well as maintenance.
