“The Spray Valves of series 20 provide a solid basis for multiple spray applications. The Spray Valves are suitable for an intermitting as well as a continuing application of different media (e.g. oils, separating agents, paint, greases etc.). The valves are controlled via an external, pneumatic 3/2-way valve. The valve needle is opened by the pressure of the compressed air and closed by spring pressure. A separate atomizer air inlet allows you switch the atomizer air for this series independently, regardless of the status of the compressed air.”
