Type description


The Bürkert welded tandem valves for SAP (Sterile Access Port) and GMP (GoodManufacturing Practice) are suitable for the control of highly purified, sterile,aggressive or abrasive mediums. The configuration consists of two forged valve
bodies. They are fully drainable and are operated either pneumatically or manually.

﻿﻿The required configuration can be selected in two ways. The first refers to thegeometry and the body and diaphragm material. The second refers to body size,
connections and surface quality.

3.3. Example of available membrane materials
The diaphragms have been developed to meet the unique challenges of hygienic and sterile requirements. Bürkert offers diaphragms with
precise material composition and high accuracy. Bürkert diaphragms are available in a wide range of materials which have been tested andproven in applications in the food and beverage, biotechnology, pharmaceutical and cosmetics industries. The diaphragms are tested
during development and production to ensure reliability under difficult process conditions.
• EPDM (AD)• PTFE/EPDM (EA)
• Advanced PTFE/EPDM (EU)• Laminate of GYLON® and EPDM (ER)For further information please refer to our flyer “Diaphragm competence for hygienic applications” on our website .
