The Müller Containment Valve (MCV) is a stable and robust split butterfly valve that is also pressure tight, making it suitable for transferring highly potent or toxic substances. The seal around the valve disk has been made very small to reduce costs, and the valve disk can be exchanged in less than 5 min. The MCV is suitable for OEB 4 (OEL 1–10 µm/m 3), is GMP compliant and is available in sizes of DN 100, 160, 200 and 250. The valve is dust and liquid tight at pressures up to 2 barg, with higher pressures possible upon request. Product-contacted components are in AISI 316L stainless steel (or Hastelloy upon request), with a PTFE seal. — Müller GmbH, Rheinfelden, Germany
