Spirax Sarco CVS10 Sanitary Check Valve – ASME BPE Compliant for Pharma & High Purity Applications
Spirax Sarco CVS10 sanitary check valve for pharmaceutical and high purity systems. ASME BPE compliant, FDA/USP VI elastomers. Available at PC Engineering
Overview
The Spirax Sarco CVS10 is a sanitary check valve engineered specifically for pharmaceutical manufacturing, biotech facilities, and high purity fluid systems. Designed and manufactured to comply with the latest ASME BPE standards, the CVS10 prevents reverse flow and cross-contamination in critical process lines.
This check valve is available with a metal seat as standard for clean steam and condensate applications. For high purity liquid services such as WFI (Water For Injection) systems, optional soft seat configurations in EPDM, Viton, or FEP-Silicone are available. All elastomers meet FDA CFR 21 para 177 and USP Class VI compliance requirements.
The CVS10 features a low opening pressure of 0.507 psi (35 mbar) and delivers a high Kv value with minimal pressure drop, ensuring efficient flow in sanitary piping systems. Surface finish options support sterility and reduce microbial growth risk.
