Electric Control Valve Manufacturer in Canada

How Does an Electric Control Valve Work?
An electric control valve receives a signal from a PLC or DCS control system and moves the valve plug to the position that delivers the required flow, pressure, or temperature. The actuator runs on 24V DC, 110V AC, or 230V AC power supply, eliminating the need for compressed air completely.
As the process condition changes, the control system sends an updated signal and the valve adjusts its position accordingly. A built-in position feedback signal continuously reports actual valve position back to the control system, keeping the process stable and within the required parameters at all times.
Key Design and Performance Features:
-
High positioning accuracy for stable modulating control in demanding process applications

Selecting the Right Electric Control Valve:
Getting electric control valve selection right involves matching the valve characteristics to the process requirements from the start.
-
Flow Characteristic – Linear trim suits flow control applications with a consistent relationship between valve opening and flow, equal percentage trim suits pressure control and applications with varying pressure drop
-
Fail Safe Requirement – Fail-open or fail-close position must be defined based on process safety requirements
-
Power Supply – 24V DC, 110V AC, or 230V AC availability at the installation point determines actuator specification
-
Signal Type – 4 to 20 mA is standard for modulating control, confirm compatibility with the existing PLC or DCS system
-
Body Material – Matched to process fluid corrosivity, temperature, and pressure class
Precise electric actuation, accurate positioning, and seamless control system integration make electric control valves a dependable choice for automated process environments. As a prominent Automated Electric Control Valve Manufacturer, Valves Only Canada manufactures electric control valves across major body materials, pressure classes, and flow characteristics.
