DELTA VPN Check Valve Overview
Purpose and Operation
The DELTA VPN check valve prevents liquid reflux within processing pipelines. It opens automatically under liquid pressure acting on a spring-loaded valve disc and closes when the forward flow stops, triggered by the preloaded spring mechanism.
Design and Value
This compact valve design includes minimal components and serves as a cost-effective alternative to the DELTA RUF3 valve—ideal for hygienic and industrial flow control applications.
