DCV10 (stainless steel) and DCV10C (carbon steel) disc check valves are designed to be mounted between flanges for pumping or other recirculating applications in a wide range of media such as process piping, hot water, steam and condensate systems, etc. Compared to conventional disc check valves, the center guide design ensures a longer and more reliable service life. The check valve guarantees the correct flow of condensate or other suitable fluids and prevents backflow at the same time.<\/p>\n

Standards: Designed to meet BS EN 14341: 2006, this product is fully compliant with the European Pressure Equipment Directive 97\/23\/EC and can be CE marked on request. Spool and seat seals are in accordance with EN 12266-1: 2003 F class.<\/p>\n

Certificate:This product can provide EN10204 3.1 material certificate.Note:If you need to provide material certificate or inspection certificate, please specify when ordering.<\/p>\n

Working Principle<\/h3>\n

The DCV10 and DCV10C disks open due to pressure during positive fluid flow and are closed by spring force before reverse fluid flow occurs.<\/p>\n
