ZQ Electric Ball ValveOverview

ZQ electric ball valve is an industrial automation execution unit consisting of a high-performance intelligent electric actuator and a rotary ball valve body. By receiving standard 4-20mA DC analog signals or switch signals from control systems, the actuator provides rotational torque to drive the ball within a 0-90 degree range. This enables rapid cut-off, opening, or continuous proportional regulation of the media in the pipeline. Due to its minimal flow resistance, excellent sealing performance, and compact structure, the ZQ is widely used in industries such as petroleum, chemical, power, metallurgy, and water treatment where high reliability in process control is required.

ZQ Electric Ball ValveCharacteristic

1.Minimal flow resistance and high flow capacity:When fully open, the ball channel is perfectly aligned with the pipe diameter, allowing the medium to pass straight through. The flow resistance coefficient is near zero, significantly reducing pumping energy consumption.
2.Superior shut-off sealing performance:The sealing pair utilizes high-quality resilient materials (soft seal) or reinforced hard alloys (hard seal). Precision machining ensures bubble-tight sealing in the closed position, meeting ANSI Class VI standards.
3.Intelligent integrated electric drive:Equipped with an intelligent electronic actuator with a built-in servo system. It supports non-intrusive field settings, overload protection, stall alarms, and fail-safe logic for advanced automation management.
4.Reliable mechanical self-locking:The transmission mechanism uses a high-strength worm gear structure providing natural self-locking. During power loss or signal failure, it firmly holds the valve position against pressure fluctuations to maintain stability.
5.Broad material and condition adaptability:The body is available in cast steel, stainless steel, or special alloys. Internal parts can be hardened based on media characteristics, allowing the valve to handle high temp, high pressure, and corrosive environments.
6.Convenient manual override:Standardized with an independent emergency handwheel for manual intervention during power loss or maintenance. The transition is smooth, ensuring reliable 24/7 operability.
7.All-weather housing protection:The die-cast aluminum alloy housing with industrial-grade anti-corrosion coating provides excellent sealing. Rated at IP67 or above, it is highly resistant to dust and water in harsh outdoor environments.
8.Modular maintenance:The simple structure has few moving parts and a long service life. The actuator-to-body interface follows ISO 5211 standards, allowing for actuator inspection or replacement without removing the valve from the line.
