BEST C600 / C610 Series Electric Valve – Switch Type & Regulating Type

The BEST C600 and C610 Series Electric Valves are compact electric valve assemblies designed for automated flow control in industrial pipeline systems. The series includes two-position switch-type models and proportional regulating models, providing flexible control options for different applications.

The C600 series is normally equipped with a two-piece threaded high-platform electric ball valve, while the C610 series is an electric butterfly valve. Both configurations feature a compact actuator with a visual valve position indicator and a manual operating device.

The actuator is equipped with a motor protection function that automatically cuts off power when a locked-rotor condition occurs. Its compact structure and lightweight design make the series suitable for installations where space and actuator size are important considerations.

Technical Specifications

Actuator Performance

The actuator performance depends on the selected model and power supply.

Available Power Supplies

• DC12V

• DC24V

• AC24V

• AC85–240V

Switch-Type Actuator

• Rated current: 0.4A at DC12V

• Rated current: 0.25A at DC24V and AC24V

• Rated current: 0.2A at AC85–240V

• Available action times: 7 seconds, 9 seconds or 12 seconds, depending on configuration
