QT-DK55-VF Explosion-Proof Electric V-Port Flange Ball Valve – Modulating Control with Fiber Shearing Function

The QT-DK55-VF is a high-precision explosion-proof electric V-shaped ball valve engineered for superior regulating performance. Compatible with 4-20mA or 1-5VDC control signals, it delivers accurate adjustment of pressure, flow, and temperature. The valve features a specially designed V-notch core that generates a powerful shearing force against the hard-sealed seat, effectively cutting through fibers and solid particles to prevent clogging. Offering a large adjustable ratio and excellent sealing, it is a cost-effective, high-performance alternative to imported brands for complex industrial applications.

Size Range: DN15-DN200

Material: WCB, Stainless Steel etc.

Connection Standard: GB / ANSI / JIS /DIN

Features

An intelligent explosion-proof V-port ball valve offering precise 4-20mA modulating control and a self-cleaning shearing action to handle fibrous fluids without clogging.

✅Precise Modulating Control (High Rangeability): Driven by a single-phase power supply and accepting 4-20mADC/1-5VDC signals, this valve offers high adjustment accuracy and a large adjustable ratio (rangeability), ensuring smooth and stable control of process variables.

✅Anti-Clogging Shearing Action: The unique V-shaped cut on the ball core creates a scissor-like shearing effect when rotating against the hard-sealed seat. This design cuts off fibers, slurries, and viscous media, preventing the valve from getting stuck or clogged.

✅Explosion-Proof Automation: Integrated with a robust explosion-proof electric actuator, the QT-DK55-VF guarantees safe and reliable operation in hazardous environments containing flammable gases or dusts.

✅Superior Sealing & Hard Seal Design: Featuring a hard-sealed valve seat structure, it provides excellent sealing performance and durability, even when handling abrasive media, minimizing internal leakage and maintenance needs.

✅Compact & Efficient Replacement: With its lightweight design and high circulation ability, this valve serves as a perfect replacement for bulky imported products. It is suitable for most regulating scenarios (excluding small caliber or 3-way requirements).
