How to Choose the Right Type of Valve: A Practical Guide for Industrial Buyers

Electric Valves

Electric valves are powered by electric actuators, offering high precision and remote control capabilities. They’re ideal for automated systems that require accurate flow regulation or remote access—such as water treatment facilities, HVAC systems, or industrial automation lines. Electric valves are a great fit when you need slow and stable actuation, frequent cycling, or remote operation via a control panel.

They are more expensive up front but require less maintenance long-term, especially in clean environments. For instance, electric ball valves are well-suited for water, chemical, or steam pipelines where manual operation isn’t feasible.

Use electric valves when: - Precision and remote control are required - The application requires modulating control (not just open/close) - Electric power is available and preferred over air.

Pneumatic Valves

Powered by compressed air, pneumatic valves are known for fast, reliable operation. They’re widely used in hazardous or explosive environments, such as petrochemical plants or gas pipelines, where using electrical actuators could pose a fire risk.

These valves respond quickly and are generally safer in flammable gas environments. However, they rely on a stable air source and may require more frequent maintenance for seals and fittings.

Choose pneumatic valves when: - Speed is crucial (e.g., emergency shutoff) - You’re operating in ATEX-rated explosive environments - Air infrastructure is already available on site

Diaphragm Valves

Diaphragm valves use a flexible diaphragm to control the flow of media. This design separates the fluid from the moving parts, making them excellent for corrosive, viscous, or particle-laden fluids. Common industries include chemical processing, wastewater treatment, and pharmaceutical manufacturing.

They offer smooth flow paths and reduce dead spots, helping prevent contamination. That makes them ideal for sanitary applications and where clean-in-place (CIP) is essential.

Use diaphragm valves when: - Fluids are abrasive, corrosive, or particulate-heavy - You need hygienic, easily cleaned flow paths - The system must prevent media exposure to actuator components

Our diaphragm valves cover various materials including PVDF, PTFE-lined, and stainless steel.

Control Valves

Unlike on/off valves, control valves regulate flow continuously based on control signals. They’re a core part of process automation in industries like power generation, chemical production, and food processing.

They respond to input from sensors and controllers, adjusting their position to maintain pressure, temperature, or flow rate. Available with electric or pneumatic actuators, these valves are perfect for precision applications requiring feedback loops.

Consider control valves when: - You need modulating control of flow/pressure - The system requires integration with PLC/DCS - Precision and consistency are critical

Key Selection Factors

When selecting the right valve, here are the primary factors to consider: - Media characteristics: Is it corrosive, clean, viscous, or has particles? - Control needs: Do you require modulating flow control or simple open/close? - Power source: Do you prefer electric, pneumatic, or manual operation? - Environment: Is it hazardous, outdoor, or temperature-sensitive? - Frequency of use: For frequent cycling, choose actuated options; for static use, a simple manual valve may suffice

Final Thoughts

No one valve fits all scenarios. If you’re working with complex systems, choosing the wrong valve could lead to inefficiencies, leaks, or even system failures. If you’re still unsure, don’t hesitate to contact our technical team for free assistance.
