Valvcon V-Series Electric Actuator
Metso’s Valvcon V-Series is a compact, rugged, reliable electric actuator designed for quarter-turn valve and damper applications. V-Series actuators are available in NEMA 4/4X and NEMA 4/4X/7&9 configurations, are CSA (C US) Certified, CE Compliant, and NEMA 4/4X/7&9 models are also certified to ATEX Directive 94/9/EC. V-Series actuators are available in a variety of control configurations from On/Off to Automatic Cycling, to Analog Modulating; with a host of other options available, they are extremely well-suited to a multitude of demanding process applications.V-Series actuators provide several levels of protection against overloads and overheating.
Thermal Overload Breaker
If the motor is running too hot, for any reason, it will automatically be disconnected until it cools down. After cooling, it will resume normal operation.Fuse Protected Input Power
On AC Hot and AC Common connections. If power is mis-applied, the fuses will isolate damage to the Motor Board, allowing for easy repair.Auto-Resetting Fuses for Limit Indicator Outputs
Protect the limit switches and internal circuitry from overloads caused outside the actuator. The working limit is .25 amps, enough for any pilot or indicator applications. They reset automatically, approximately 3 minutes after the overload condition is corrected.Stall Protection (Modulating Applications)
If the actuator cannot achieve the position commanded by the control signal, it will automatically disconnect power to the motor until the control signal commands the actuator to drive in the opposite direction.Electrical Interference and Emissions
The actuator has been carefully designed to minimize electrical interference with other equipment. Emission levels comply with Part 15 of the FCC Rules for Class A electronic equipment.
