The main process data and product properties of the stored medium as well as the temperature of the stored product determine the material for the specific valve. Subsequently the nominal diameter and the type of connection are checked and selected.
The in-tank valve is available in nominal diameters of DN 150 mm / 6"and DN 200 mm / 8", whereas the connection for the pneumatic actuating device has a nominal diameter of DN 80 mm / 3".
The length of the actuator rope and of the emergency rope is determined by the height of the tank. The final adjustment is completed during installation. The material for the gasket is determined based on the operating conditions and/or other special requirements.
The material of the valve bottom plate needs to be compatible to the material of the tank bottom plate. If the material of the bottom plate is provided by the tank manufacturer, then close coordination between manufacturing planning and installation planningis necessary.
For special requirements the valve and the actuation system (e.g. with inductive position indicator) can be supplied with a special design.
Deviations from our standard design will be sized and specified with the support of our engineers for the specific application.
