Match Accessories to Valve Type

Not all valves are the same. Ball, butterfly, gate, and globe valves each have unique characteristics, and the accessories you choose must match accordingly.

The wrong combination leads to poor control and premature wear. The right combination improves reliability and reduces costs.

Here is a quick breakdown.

Ball Valves – Quarter-Turn, On/Off Focus

Ball valves are built for tight shut-off and fast operation.

Key accessories:

• Quarter-turn actuator (pneumatic or electric)

• Solenoid valve for remote control

• Limit switch for position feedback

• Positioner only if modulating control is needed

Tip: Ball valves need high breakaway torque. Oversize the actuator slightly for reliable opening.

Butterfly Valves – Lightweight, Versatile

Butterfly valves are economical, ideal for large diameters, and suitable for both on/off and basic modulating service.

Key accessories:

• Quarter-turn actuator

• Positioner for modulating applications

• Filter regulator for stable air supply

• Limit switch for remote indication

Tip: Butterfly valves have non-linear flow. Use a positioner with customizable curves for smoother control.

Gate Valves – Isolation Only

Gate valves are designed for fully open or fully closed service—never for throttling.

Key accessories:

• Multi-turn actuator (electric or pneumatic)

• Solenoid valve for pneumatic versions

• Limit switch for open/closed status

Tip: Gate valves require high seating torque. Ensure the actuator delivers enough force at the final closing position.

Globe Valves – Precision Modulating

Globe valves are the go-to choice for throttling and precise flow regulation.

Key accessories:

• Multi-turn actuator

• Positioner (essential for accurate control)

• Filter regulator for clean, stable air

• Limit switch optional (positioner often provides feedback)

Tip: Globe valves need high thrust. Choose an actuator that delivers consistent force across the full stroke.

Quick Reference Table

Environmental Factors Matter Too

Beyond valve type, consider the operating environment:

• Hazardous areas – Use certified explosion-proof accessories.

• Corrosive conditions – Choose stainless steel or coated enclosures.

• High cycle rates – Opt for proximity switches over mechanical types.

• Extreme temperatures – Verify accessory ratings for ambient conditions.
