Spirax Sarco CVS10-1M Clean Metal Seat Check Valve

Description

Spirax Sarco CVS10 Clean Metal Seat Check Valves are spring-loaded, clean check valves manufactured in 316L stainless steel, designed to prevent backflow of fluids in pipelines. 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.

(an official) standard

• The CVS10 is fully compliant with the European Pressure Directive 97/23/EC.
• CVS10 designed to meet ASME BPE standards

Shutdown Criteria

Metal-seated CVS10 shut-off according to EN 12266 - 1:2003 Rate D

Certification

• EN 10204 3.1 Material certificate
• Typical Surface Polishing Certificate (Note: If a certificate or inspection is required please specify when ordering)

wrap

The product is isolated from other non-stainless steel products and packaged separately in a clean environment. In accordance with ASME BPE standards, the inlet and outlet connection ends are sealed with caps, and the entire valve is sealed in a plastic bag to avoid dust ingress.

(of a computer) run

The valve opens by fluid pressure. When the fluid stops flowing, the spring closes the valve before the fluid flows backwards.
