Electric Valve: Types And Applications | Juchang Precision

Juchang Precision shares professional knowledge of valves widely‑used in industrial automation. An electric valve is an automatic control valve driven by an electric actuator powered by motor, to realize valve opening, closing or stroke adjustment. It is extensively deployed in automated fluid pipeline control systems.

1. Main Types of Electric Valves

• Quarter‑turn electric valve: Matched with quarter‑turn electric actuator delivering 0‑90° rotary motion. It drives ball valves, butterfly valves, plug valves and other valve bodies to control pipeline fluid on‑off by rotation movement.

• Linear‑stroke electric valve: Equipped with linear‑stroke electric actuator producing reciprocating linear push‑rod motion to drive valve disc up and down. Mostly applied for control valves and globe valves to achieve shut‑off and flow modulation.

Both types are commonly adopted in highly‑automated complete industrial equipment. They can integrate with PLC control systems for remote management.

2. Main Applications of Electric Valves

Electric valves serve as analog AI control components for analog flow regulation in liquid, gas and air duct pipelines. They also function as two‑position on‑off valves for large‑bore valves and HVAC air dampers. Supporting AI feedback signals, they accept DO switch signals or AO analog regulating signals. They are widely used in large‑scale process pipelines and HVAC air‑damper systems.

3. Operating Characteristics of Electric Valves

• Switching mode: Motor‑driven design. It takes certain execution time for full opening or closing. Belongs to analog‑type component supporting partial‑stroke adjustment.

• Working property: Motor‑driven with good voltage‑shock resistance. Compared with solenoid valves which feature instant fast open‑close for low‑pressure, low‑flow and high‑frequency cycling scenarios; electric valves have relatively slow actuation speed yet adjustable opening degree. Multiple statuses including fully‑open, fully‑closed and half‑open are available for continuous pipeline flow modulation, which cannot be realized by solenoid valves.

• Applicable processes: Capable of both flow regulation and simple on‑off control. Widely used in HVAC fan‑coil terminals, chemical industry, water treatment, power generation and other sectors.
