Description

The DELTA VPN check valve is used in places at which the reflux of liquids into the pipeline must be prevented. The valve opens through the pressure of the liquid against the spring-loaded valve disc. The closing process is introduced by the preloaded spring when the liquid flow into the flow direction stops. The valve which only consists of a few parts, is a cost-effective alternative to the DELTA RUF3 valve. SPECIFICATIONS Housing, valve, disc, guide, cover are made of stainless steel grades 1.4571 / 1.4404 (DIN EN 100888). Available seal materials are EPDM and Viton. Nominal dimensions: DN 25 DN 100 and ISO 1 4.
