QT-DK55-3T Explosion-Proof Electric 3-Way Ball Valve – Internal Thread (T-Port/L-Port) with Modulating Control

The QT-DK55-3T is a versatile explosion-proof electric three-way ball valve designed for complex fluid automation. Compatible with AC220V/380V or DC24V, it accepts 4-20mA signals for precise proportional adjustment or two-position switching. Featuring a robust internal thread connection, this valve offers flexible flow patterns: the L-Port configuration efficiently diverts flow, while the T-Port enables mixing and proportioning of liquids, gases, and steam. It is the ideal solution for integrating domestic and foreign technologies into a safe, high-efficiency industrial control system.

Features

An intelligent explosion-proof three-way threaded ball valve offering T-port mixing and L-port diverting capabilities with precise 4-20mA signal modulation for hazardous industrial environments.

✅Versatile Flow Control (T-Port & L-Port): Offers configurable flow patterns: The L-Port is designed for switching flow direction between two perpendicular pipes (diverting), while the T-Port excels at mixing, confluencing, or proportioning three different pipelines for flexible system layout.

✅Precise Proportional Modulation: Accepts standard industrial control signals (4-20mA or voltage inputs) to achieve accurate proportional regulation of pressure, flow, and temperature, making it perfect for automated process control systems.

✅Explosion-Proof Safety: Equipped with a high-performance explosion-proof electric actuator, it ensures safe and reliable operation in hazardous areas containing flammable and explosive media, such as petroleum and natural gas.

✅Wide Voltage & Signal Compatibility: Supports multiple power supply options (AC220V, AC380V, DC24V) and integrates seamlessly with PLC or DCS systems, offering a “smart” solution that replaces traditional manual switching valves.

✅Compact Internal Thread Design: The internal thread connection allows for easy, space-saving installation in existing pipelines. Its integrated structure combines domestic and foreign technologies to provide low resistance, light weight, and high sealing performance.
