Solenoid-operated valves in action
In-line isolation valve VV 25, 230 V / 50 Hz, KF DN 25
These straight-through valves with electromagnetic (solenoid) drive are used for operating cycles with short intervals and, therefore, are often used as vacuum control valves. The straightforward design provides a valve with low leakage rate. The valves in version VV C are made of materials with excellent chemical resistance. The valve sealing of the VV-B 6C is made of a special fluoroelastomer with better form stability than common PTFE, much higher chemical resistance than FKM and excellent long-term leak tightness characteristics.Technical data and graphs
