Electrothermal Servo Controls for Shutter Valves Series V3EC

ELECTROTHERMAL SERVO CONTROLS FOR SHUTTER VALVES SERIES V3EC

MAIN CHARACTERISTICS : V3EC servocontrols have been designed for use on domestic heating and cooling systems, where compact dimensions and ease of assembly are required. The closing force of the valve stem is guaranteed by a spring couple to a wax expansion element. To motorise the manually controlled shutter valves, predisposed to be controlled by these servocontrols it is sufficient to unscrew the manual knob completely and screw the ring nut of the actuator for the quick coupling to the servocontrol. All this is done without having to drain the system (see table 3 for the valves predisposed for these servocontrols).

Distance between the valve body rabbet and of the shutter shaft in low position = A 11

Distance between the valve body rabbet and of the shutter shaft in high position= A 17, 5

INSTALLATION Remote the handwheel or the cap from the valve body. Install the actuator, exerting light pressure, and screw the knurled ring nut of the actuator onto the valve body. Do not use spanners, box wrenches or similar tools. Make the electrical connection. Important notes for maintenance. The power cable must never be replaced. Opening the actuators will cause irreparable damage to the device. Faulty actuators must be completely replaced. Warnings. The actuator must NOT be installed below the valve body.

 

Robust Electrothermal Servo System

Our shutter valve actuators employ an advanced electrothermal servo system, ensuring rapid and precise valve movement for effective liquid and gas regulation. With a durable enclosure rated IP54, the system functions reliably in demanding industrial settings, providing longevity and resistance to dust and splashes. Whether installed horizontally or vertically, these controls adapt to various application needs, delivering over 50,000 operating cycles.


Versatile Application and Comprehensive Compatibility

Engineered for seamless integration in industrial automation, HVAC, and liquid flow management, our servo controls accommodate diverse media like water, oil, and gas. With valve sizes ranging from 1 inch to 8 inch and connection options of threaded or flanged, they offer exceptional flexibility. High-quality sealing with EPDM and PTFE guarantees compatibility and enhanced leakage prevention under pressures up to 1.6MPa.
