The new Model CV check valve (photo) features a sealing system with a self-centering piston, which reliably prevents backflow of liquid and gaseous media. The reliability of the new instrumentation valve is mainly due to its redundant sealing, consisting of an O-ring and a metal cone. Its leak-tightness has been tested in accordance with BS6755/ISO 5208 leakage rate A. The solid-machined, robust design of the Model CV ensures high repeatability and a long service life, even in heavy-duty applications. An application-specific assembly with a measuring instrument is offered. Such an instrument hook-up is delivered ready-to-install and leak tested. — WIKA Alexander Wiegand SE & Co.
