Diaphragm valve Multi block

Compact stainless steel diaphragm valve multiblock with stainless steel or plastic actuators for the pharmaceutical industry.

Romynox delivers SED multi block diaphragm valves for high purity applications in the pharmaceutical, food, fine chemical and cosmetic industries. The SED multi block diaphragm valves includes the same features and performance of a standard 2-way diaphragm valve of the KMA and Steripure series. By using SED multiblock the diaphragm valves design process circuits can be assembled from one block of stainless steel. Due to a minimal of contact makes the system faster. And cleaning is easier  (CIP –SIP). With this design seal mass will be removed as much as possible. This will increase the heat absorption and the valve assembly quickly sterile (SIP).
