SED - Tandem Diaphragm valve
Compact welded configuration of stainless steel diaphragm valves with stainless steel or plastic actuator
Features
- Two valves are welded together
- Designed for processes in aseptic production plants
- Reducing dead leg in accordance with cGMP
- Different finishing available
These welded diaphragm valve configurations are specifically designed for processes in aseptic manufacturing plants, reducing dead leg in accordance with cGMP.
Romynox supplies SED tandem diaphragm valves configurations for high purity applications in the pharmaceutical, food, fine chemistry and cosmetic industries. These welded membrane valve configurations are specifically designed for processes in aseptic production plants, and reduce dead laying in accordance with cGMP.
Various configurations are possible; from simple tandem assemblies, where two valves are welded together, to very complex configurations of various diaphragm valves of different sizes, brought together in a cluster. Within SED there is strict quality control for every welded joint in the configuration. All accessible welds are polished to internal surface specifications. Then the configuration of the diaphragm valves is visually inspected and tested for maximum pressure.
During the installation of welded diaphragm valve configurations, it is important to follow proper guidelines for the drainability of the diaphragm valve assemblies.
