Product Summary

The ring check valve refers to a check valve, for use as an insert check valve, with a valve seat and a valve element that is resiliently prestressed against the valve seat by a valve spring.

Based on the production, a retaining element embodied as a retaining bracket is given, which supports the end of the valve spring remote from the valve element and the retaining element can be locked resiliently to a recess, particularly an annular groove, of the valve housing. This enables fast, simple assembly of the check valve from its individual parts. This mode of flow regulation is required to prevent return flow, to maintain prime after the pump has stopped, to enable reciprocating pumps and compressors to function, and to prevent rotary pumps and compressors from driving standby units in reverse.
