Electronically controlled motor driven rate valve is designed for accurate feed of chlorine gas and other technical gases into water.
Made of high quality materials, resistant to high concentrations of aggressive gases. Built-in seals are made of fluorinated hydrocarbons (FKM, PTFE), materials resistant to aggressive gases.
Manual control over integrated keyboard and full manual control over top hand wheel; automatic control over current or voltage input and via digital communications.
Fault signal is visible through the user interface or via a digital output.
The non-linearity of the valve can be repaired by software in five points.
Built-in security feature: In case of power loss the valve has a battery backup that closes or opens the valve. It also allows completely mechanical handling in case of power loss.
For larger vacuum lines, see table: Chlorine vacuum line size requirements
Analog output value < 3,6 mA or >21,6 mA indicating valve failure
