Apv VPN Check Valve

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.
