The pneumatically actuated P40 PD tank-bottom valve (photo) is designed for use in sterile applications. The sealing principle of the valve is based on the company’s PD sealing technology, which hermetically separates the actuator from the medium. All actuator parts (except the sealing and design elements) are made from stainless steel. The valve has an optimized drain design. — GEMÜ Gebr. Müller Apparatebau GmbH & Co. KG, Ingelfingen, Germany
