The number that matters
Nominal pressure
16bar
The pressure class of the valve body at 20 °C. Working limits depend on the medium and its temperature.
Construction
Parts and materials
Butterfly valves are designed for use as shut-off or regulating valves for flow control in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.
Electric quarter-turn actuators Elerhant are designed for remote and local control of shut-off valves. They are widely used in gas, oil, metallurgical and food industries, in housing and communal services, etc. including heating and hot/cold water supply systems. The use of electric actuators for shut-off valves allows to achieve automation of processes and facilitates control over the technique. The installation dimensions comply with the international standard ISO 05211 / DIN3337.
