In-line diaphragm check valves for low- and medium-pressure gaseous fluids.
The check valve is fitted with a Viton or ethylene-propylene diaphragm to ensure maximum safety under all operating conditions.
When used with gases for the food industry, the component materials are treated with the Niploy Process to ensure non-toxicity and prevent bacterial growth and hazardous oxidation.
For use with oxygen, the valves are degreased.
