Electric Globe Control Valve - Specifications and Features

Hello, this is VALVEPARK.

In industrial plants, power stations, and chemical, petroleum, and water treatment facilities, precise flow control and stable operation are paramount. Achieving these requirements demands reliable control valves. Today we introduce the key specifications and features of the Electric Globe Control Valve.

What Is an Electric Globe Control Valve?

An electric globe control valve uses an electric motor actuator to control the valve's opening degree, enabling precise regulation of fluid flow (water, steam, gas, oil, etc.) in pipelines. It is an automatic control valve.

Key Features

Precise Flow Control

Available flow characteristics: Equal Percentage / Linear / Quick Open. Multiple flow characteristics allow stable flow control tailored to process conditions.

Wide Range of Specifications

• Sizes: 1" (15A) ~ 10" (250A)
• 15A-50A: Compact design for small lines
• 80A-150A: Main sizes for general plant applications
• 200A-250A: High-flow, high-pressure line applications
• Pressure ratings: JIS 10K-40K / ANSI 150#-2500# / PN10 - PN40
• End connections: Flanged, butt weld (BW), socket weld (SW), threaded (NPT, BSPT)

Robust Material Construction

• Body materials: WCB, CF8, CF8M, CF3M
• Trim materials: 304 SS, 316 SS, 316L SS - with optional Stellite #6 hard-facing on seat and plug

Optimal body and trim materials can be selected based on fluid properties, temperature, and pressure conditions.

Reliable Electric Actuator System

The electric actuator applied to this product is designed for high reliability in continuous industrial duty and adapts to various control environments.

Power Supply

• AC 110 / 220V (single-phase)
• AC 380 / 440 / 460V (three-phase)
• 50/60Hz compatible - suitable for both domestic and overseas plant power standards

Protection Rating

• IP67 weatherproof and dustproof
• Optional: Explosion-proof Ex d IIB T4, IP68 (10m submersion for 72 hours)

Standard Built-in Devices

• Limit Switch: Detects open/close valve position
• Torque / Force Switch: Automatically shuts off in case of overload or mechanical fault
• Thermal Protector: Automatically cuts power on motor overheating to prevent damage

Safety and Protection Functions

The electric globe valve incorporates multiple safety protection features as a top priority for operational stability and equipment protection.

• Overload protection: Automatically shuts off when abnormal torque occurs during valve operation; protects gears and motor
• Motor thermal protection: Built-in thermal protector; auto power-off when temperature limit is exceeded, resumes automatically once temperature normalizes

Applications

Power Generation & Energy Facilities

Used as automatic control valves for flow and pressure control in steam, feedwater, and auxiliary piping systems of thermal, combined cycle, and nuclear power plants.

Oil, Gas & Chemical Plants

Process control service for high-temperature, high-pressure, and corrosive fluids in refinery, petrochemical, and gas processing operations.

Water & Wastewater Treatment

Automatic valve systems for flow distribution, isolation, and control in potable water, industrial water, and wastewater treatment processes.

Semiconductor & Precision Process Equipment

Process control valves requiring precision control and high reliability in UPW, process gas, and chemical lines.

General Industrial Automation Piping

Electric control valves integrated with central control systems in HVAC, process equipment, and production line automation piping.

Selecting a valve is not simply a product purchase - it is an investment in process reliability. VALVEPARK provides optimized solutions suited to your site conditions. Inquiries about electric globe control valves are always welcome.
