QT-DK55-3PS Explosion-Proof Electric 3-Piece Ball Valve - Internal Thread with Quick-Maintenance Design
Designed specifically for critical safety in flammable and explosive environments, the QT-DK55-3PS is a premium explosion-proof electric ball valve featuring a versatile three-piece body structure. This modular design allows for rapid inline maintenance—enabling the replacement of valve seats and spheres without removing the entire unit from the pipeline. Equipped with an internal thread connection and a double-sealed structure, it ensures zero leakage and reliable shut-off or flow control for petroleum, chemical, and natural gas applications.
Features
A high-safety explosion-proof electric ball valve featuring a maintenance-friendly three-piece threaded design and double-sealing technology for hazardous industrial applications.
✅Modular 3-Piece Design for Quick Maintenance: The three-piece valve body structure is engineered for efficiency. It allows for easy disassembly and replacement of internal components (seats and spheres) without cutting the pipe, significantly reducing downtime and maintenance costs.
✅Comprehensive Explosion-Proof Safety: Powered by a certified explosion-proof electric actuator, this valve guarantees safe operation in hazardous zones containing flammable gases or dust, meeting strict industry standards for petroleum and chemical processing.
✅Double-Sealed for Zero Leakage: Featuring an advanced double-sealed structure, the valve eliminates the risk of both internal and external leakage. This ensures the integrity of the pipeline system and prevents environmental contamination or safety hazards.
✅Versatile Internal Thread Connection: Designed with precise internal threads (NPT/BSP options usually available), the valve offers a secure and simple installation method, making it compatible with a wide range of existing pipeline infrastructures.
✅Durable & Precise Flow Control: Combining a robust metal body with high-quality sealing materials, the valve withstands harsh working conditions while providing accurate medium cutoff and flow regulation capabilities.
