Sanitary Butterfly Valve with Pneumatic Actuator and C-TOP Control Module

Reference: SV-1PC-C
Sizes available: 1/2" to 12" (DN10 - DN300)
End connection: tri-clamp / tri-clamp
Body & Disc: AISI 304 or 316L, (EN1.4301/EN1.4404)
Seat: EPDM, VMQ (Silicone) or Viton (FPM), FDA approved.
Max. working pressure: 145psi (10bar)
Temperature range: 14°F ~ 248°F (-10°C ~ 120°C) as default, higher available upon request.
Operation: pneumatic actuator, 304SS, vertical type, NC/NO/AA.
Actuator air pressure: 58 ~ 102psi (4 ~7bar)

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.

APPLICATION

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

OPERATING PRINCIPLE

C- TOP is a pneumatic control head 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 in corporates of signal sending and commanding devices to monitor all the process valves. It has following features:
● Controlled by pneumatic or electrical actuators
● Position indicator with signal feedback.
● The control head suits for pneumatic valves. It picks signal from control board or PLC, so as to send signal and operate to the valves. In addition, there are three LED lights in the C-TOP, which indicate the status of the valves.
Green = open
Red = close
Yellow = valve is operating in the third position (mixproof valve)

CONFIGURATION OF C-TOP

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 actuatuion – (one) 24-volt solenoid valve and (one) displacement inductive detector for valve position control
● Double-acting actuatuion – (two) 24-volt solenoid valves and (one) displacement inductive detector for valve position control
● Mixproof valve – (three) 24-volt solenoid valves and (one) displacement inductive detector for valve position control
