EPIC® Double Ferrule


Order On-line at our Express Line e-Store

The EPIC® Double Ferrule valve is a poppet style check valve with compression tube connections. These connections are interchangeable with the most commonly used double ferrule connections in instrumentation applications. The check valves are machined from 300 series stainless steel bar stock with Aflas® seat/seals and a 1/2-PSI stainless steel spring setting (cracking pressure) that can be installed in any flow orientation. Additionally, the EPIC® series incorporates a drop-in replaceable check mechanism (EPIC® Replaceable Insert Kit sold separately) that is easily installed into the existing body without requiring additional assembly of checking components.

Due to the materials of construction, field repairability and the quality customers have come to expect from Check-All, the EPIC® check valves are uniquely suited for a very wide range of applications in liquids, gases and steam.
