C-TOP control module: With solenoid valves and inductive detectors inside, the control units are fitted to the pneumatic actuator. It receives signals from a control panel or from a PLC to actuate the valves and sends signals to the PLC or to the control panel to communicate the status/position of the valve.


SV-1PC-V-C series is a sanitary butterfly valve with a pneumatic actuator and C-TOP control unit, it is widely used in process piping systems for isolation and ON/OFF control. SV-1PC-V-C butterfly valve operates automatically with the C-TOP control module.


C- TOP is a pneumatic control head with solenoids and a displacement sensor inside, which is designed to ensure optimum control of valves. It is compatible with most automatic systems with PLCs and AS- I BUS communications. C- TOP control head incorporates signal sending and commanding devices to monitor all the process valves. It has the following features:

● Remote ON/OFF control over the valve
● Position detectors with signal feedback
● Possibility of bus communication (AS-Interface)
● LED lights indicator: Green = Open / Red = Close / Yellow = a third position (mixproof valve).
● Simple, modular and resistant that guarantees maximum flexibility.


The design of the C-Top unit is simple, modular and resistant that guarantees the maximum flexibility. The C-TOP units can be set up according to the customer’s requirements.

Configuration of C-TOP:
● Single-acting actuation – (one) 24-volt solenoid valve and (one) displacement inductive detector for valve ON/OFF control
● Double-acting actuation – (two) 24-volt solenoid valves and (one) displacement inductive detector for valve ON/OFF control
● Mixproof valve – (three) 24-volt solenoid valves and (one) displacement inductive detector for valve ON/OFF control
