Product Summary

A vent check valve is commonly for use with a fluid pump. The vent check valve comprises a floatation chamber and floatation member therein so that air is allowed to flow therethrough during normal operation of the pump while the liquid is prevented from flowing therethrough in the event of a malfunction of the pump. The vent check valve also comprises a porous member thereon which allows air to flow therethrough while preventing direct access into and contamination of the vent check valve. 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. Check valves may also be required.
