Structure and External Dimension 

BEST BdC600 / BdC610 Series Small Explosion-Proof Electric Valve

The BEST BdC600 and BdC610 Series Small Explosion-Proof Electric Valves are designed for automated valve control in industrial pipeline applications. The series includes switch-type and regulating-type actuator configurations, providing electric operation for compatible two-way ball valves and electric butterfly valves.

Featuring a compact structure, lightweight design and visual valve position indicator, the BdC6 series offers a practical solution where space-saving installation and electric valve control are required. The actuator incorporates a motor protection device that automatically cuts off power in the event of a locked-rotor condition.

Technical Specifications

Power Supply and Control Signals

The actuator supports the following power supply options, depending on the selected configuration:

• DC12V

• DC24V

• AC24V

• AC85–240V

For switch-type actuators, the rated current listed in the manual is 0.8A for DC12V, 0.45A for DC24V and AC24V, and 0.15A for AC85–240V.

The regulating-type configuration supports:

• Input signal: 4–20mA DC or 0–10V DC

• Output signal: 4–20mA DC or 0–10V DC

Switch-type configurations provide passive contact output. The signal output contact capacity is specified as less than AC125V/1A or DC30V/1A.

Applicable Pressure and Temperature

Applicable Pressure

The manual specifies an applicable pressure range of 0–16 bar.

Ball Valve Temperature Range

• Carbon steel ball valve, standard configuration: -29°C to 150°C

• Carbon steel ball valve, special high-temperature configuration: -29°C to 250°C, with a raised yoke and limited to sizes DN20 and below

• Stainless steel ball valve, standard configuration: -40°C to 150°C

• Stainless steel ball valve, special high-temperature configuration: -40°C to 250°C, with a raised yoke and limited to sizes DN20 and below

Butterfly Valve Temperature Range

• Standard NBR sealing configuration: -9°C to 95°C

• Special EPDM sealing configuration with gray cast iron body: -15°C to 120°C

• Special stainless steel configuration: -39°C to 120°C

Please confirm the selected valve body, sealing material and operating conditions when choosing the applicable temperature range.

Valve Types and Connections

The BdC6 series can be configured with different valve body types:

• Three-piece threaded ball valve

• Flanged ball valve

• Wafer-type butterfly valve

The standard threaded configuration uses a three-piece high-platform ball valve. The flanged configuration uses a two-piece high-platform ball valve.

Available dimensions and connections depend on the selected valve type and nominal size.

Applications

The BdC600/BdC610 series can be used in industrial pipeline automation where electric valve operation and explosion-proof actuator specifications are required.

Typical valve configurations include:

• Two-way ball valve assemblies

• Flanged electric ball valves

• Wafer-type electric butterfly valves
