Common Uses:

     -Ozone gas backflow prevention

     -Isolation of ozone from an oxygen concentrator

     -Prevention of water damage to an ozone generator

     -Used directly on Mazzei Venturi (see below)

 

We use this venturi directly on the Mazzei venturi.  The standard check valve supplied with a Mazzei venturi is made out of Kynar material and does not always create a leak-proof connection and may leak water slowly past the seal in many situations.  By removing the stock check valve and threading this check valve directly on the Mazzei venturi, a more secure connection is possible with stainless fittings, and a positive check valve with a positive seal is used.
