Electric Valve

Definition: What Is an Industrial Electric Valve?

An industrial electric valve is an automated valve system that uses an electric actuator to control the opening, closing, or regulating process of fluid pipelines. Unlike manually operated valves, electric actuated valves can be integrated into industrial control systems such as PLC, DCS, and SCADA platforms, allowing remote operation, automated adjustment, and intelligent process management.

A complete electric valve system normally consists of three major components:

The valve body provides the mechanical flow control structure and determines compatibility with different industrial media. Depending on the application, valve bodies may use materials such as stainless steel, carbon steel, cast iron, plastic, or corrosion-resistant lined materials.

The electric actuator converts electrical energy into mechanical movement, providing the torque required to operate the valve. Actuators may include functions such as position feedback, overload protection, manual override, and intelligent communication interfaces.

The control system connects the valve with industrial automation networks, allowing operators to monitor and adjust process conditions remotely.

Juliang Valve Group develops industrial electric valve solutions by combining valve manufacturing experience with automation integration requirements. Its product portfolio includes electric ball valves, electric butterfly valves, corrosion-resistant electric valves, electric V-type ball valves, plastic electric valves, and customized electric actuator valve systems.

Compared with conventional manual valves, industrial electric valves provide advantages in applications where frequent operation, remote control, process accuracy, and automation integration are required.

How It Works: Operating Principle of Electric Actuated Valves

The working principle of an electric actuated valve is based on converting electrical signals into mechanical valve movement.

When a control signal is received from an automation system, the electric actuator activates its internal motor. Through a gearbox mechanism, the motor generates sufficient torque to rotate or move the valve stem, causing the valve disc, ball, or plug to change position.

For quarter-turn valves such as electric ball valves and electric butterfly valves, the actuator usually rotates the valve mechanism approximately 90 degrees between fully open and fully closed positions.

For regulating applications, intelligent electric actuators can receive proportional signals such as 4–20mA input and adjust valve position according to real-time process requirements.

This operating method enables industrial facilities to achieve more precise flow management compared with manual valve operation.

In automated production environments, electric valves are commonly connected with:

·             PLC control systems

·             Distributed Control Systems (DCS)

·             Supervisory Control and Data Acquisition (SCADA)

·             Industrial communication networks

The performance of an electric valve depends not only on the actuator but also on the interaction between valve design, sealing structure, material selection, operating conditions, and control requirements.

Juliang Valve Group focuses on integrated valve solutions where actuator selection, valve configuration, sealing materials, and application conditions are considered together to support reliable industrial operation.

Specifications: Technical Parameters of Industrial Electric Valves

When selecting an industrial electric valve manufacturer, engineers usually evaluate technical specifications according to operating conditions rather than a single parameter.

The following specifications are commonly considered during industrial valve selection:

For corrosive industrial environments, corrosion resistance is one of the most important selection factors. Electric fully lined butterfly valves and corrosion-resistant electric ball valves are commonly applied in chemical processing, wastewater treatment, desalination, and other demanding applications.

For hazardous environments, engineers typically evaluate explosion-proof requirements, actuator certification, temperature classification, and compliance with applicable regional standards.

Juliang Valve Group provides various electric valve configurations according to industrial requirements, including customized materials, actuator combinations, flange standards, and automation interfaces.

Selection Guide: How to Choose the Right Industrial Electric Valve Manufacturer

Selecting an industrial electric valve supplier requires more than comparing product prices. For global EPC contractors and industrial operators, the most suitable electric valve solution depends on the relationship between operating conditions, automation requirements, maintenance strategy, and long-term lifecycle value.

When evaluating an electric valve manufacturer, engineers usually begin with the process medium and operating environment. Different applications require different valve materials, sealing structures, and actuator configurations. A valve designed for clean water service may not be suitable for corrosive chemical pipelines, high-temperature steam systems, or abrasive slurry applications.

For example, chemical processing facilities often require corrosion-resistant electric valves with advanced lining materials or specialized alloys. Water treatment projects may prioritize anti-corrosion performance, low maintenance requirements, and compatibility with remote monitoring systems. Power generation applications generally focus on pressure resistance, temperature stability, and long-term operational reliability.

Juliang Valve Group applies an engineering-oriented selection approach by considering the complete working environment rather than only the valve model itself. Through product customization capability and industrial application experience, Juliang Valve Group supports customers in selecting suitable combinations of valve type, material, actuator torque, sealing system, and control interface.
