QT-DK55-2PF Explosion-Proof Electric Stainless Steel Ball Valve – 2-Way Flanged with Built-in Servo (4-20mA Control)

The QT-DK55-2PF combines industrial safety with precision control. This explosion-proof electric two-way ball valve features a direct-mount design, connecting the actuator directly to the stainless steel valve body for a compact, lightweight, and stable solution. Distinguished by its built-in servo system, it requires no external servo amplifier—simply input a 4-20mA signal and 220V AC power for immediate, precise regulation and cut-off. Ideally suited for frequent operation, it offers low flow resistance and reliable performance in hazardous environments.

Size Range: DN15-DN350

Material: WCB, Stainless Steel etc.

Features

A compact, explosion-proof stainless steel flanged ball valve featuring a direct-mount actuator with a built-in servo system for precise 4-20mA control without the need for external amplifiers.

✅Smart Integrated Control (Built-in Servo): The electric actuator comes with a built-in servo system, eliminating the need for a separate servo amplifier. This simplifies wiring and installation, allowing for precise control via standard 4-20mA signals and 220V AC power.

✅Compact Direct-Mount Structure: Adopting a direct connection between the ball valve and actuator reduces the overall height and weight of the unit. This compact design minimizes backlash, ensures stable action, and makes it ideal for tight installation spaces.

✅Explosion-Proof Reliability: Engineered for safety, the explosion-proof actuator ensures secure operation in hazardous industrial zones, suitable for handling flammable gases or liquids with strict safety requirements.

✅High Efficiency & Low Resistance: The straight-through 2-way ball valve design offers minimal fluid resistance (high flow coefficient), ensuring efficient flow for both on-off cutting and flow adjustment applications.

✅Flexible & Durable Configuration: Constructed from durable stainless steel for corrosion resistance, the actuator model can be customized based on user requirements, supporting frequent operation with long-term stability.
