Solenoid valve Serie KDV

medicalgas-liquidmedia separated

2/2-way - Normally Closed (NC) 2/2-way - Normally Open (NO) 3/2-way - Universal (UNI) The Series KDV are solenoid valves designed to control critical media such as aggressive, high purity liquids or gases or thermosensitive fluids. These valves prevent the controlled media from interacting with the internal mechanical part of the valve. The orifices are open or closed by a separation element on which acts a mechanism moved by a solenoid actuator. To choose the most suitable model for a specific application, check the chemical compatibility of the medium with the available materials of body and seals.
