This metal-seated product is widely used in the food, pharmaceutical and medical industries, primarily for steam and other harsh environments where soft seats are not suitable. EPDM, Viton and FEP - Silicon soft seal seats are available for water, process and gas applications (see TI - P029 - 10 for details). Different surface finishes are available, such as CVS10-1 polished to 0.5 micron Ra (in accordance with ASME BPE SF1) on the inner surface and 0.8 micron Ra on the outer surface, and CVS10-2 electropolished to 0.38 micron Ra (in accordance with ASME BPE SF4) on the inner surface and 0.8 micron Ra on the outer surface.<\/p>\n<h3>(an official) standard<\/h3>\n<ul>\n<li>The CVS10 is fully compliant with the European Pressure Directive 97\/23\/EC.<\/li>\n<li>CVS10 designed to meet ASME BPE standards<\/li>\n<\/ul>\n<h3>Shutdown Criteria<\/h3>\n<p>Metal-seated CVS10 shut-off according to EN 12266 - 1:2003 Rate D<\/p>\n<h3>Certification<\/h3>\n<ul>\n<li>EN 10204 3.1 Material certificate<\/li>\n<li>Typical Surface Polishing Certificate (Note: If a certificate or inspection is required please specify when ordering)<\/li>\n<\/ul>\n<h3>wrap<\/h3>\n<p>The product is isolated from other non-stainless steel products and packaged separately in a clean environment.
