DINKONDA GLOBAL Power Plants Special DN50-DN600 WCB Cast Steel/stainless Steel Clamp Type Multi-level Metal Hard Seal Electric Butterfly Valve

DINKONDA GLOBAL Power Plants Special DN50-DN600 WCB Cast Steel/stainless Steel Clamp Type Multi-level Metal Hard Seal Electric Butterfly Valve

Product Overview

The electric hard seal butterfly valve developed and manufactured by DINKONDA GLOBAL is a self controlled valve with a triple eccentric clamping metal sealing structure. It relies on an intelligent electric actuator to drive the butterfly plate to rotate 90 degrees, adapting to harsh high-temperature and particulate media conditions. It integrates two functions: pipeline flow regulation and medium cut-off. The valve adopts a clamp installation form, with a compact valve body structure, light weight, and convenient on-site pipeline assembly. The supporting integrated intelligent electric drive unit supports local operation and remote control system linkage, and is widely used in various industrial pipelines such as thermal power, metallurgy, petrochemicals, and thermal power pipelines. It is the core valve equipment for automation control of high-temperature process systems.

Structural Composition

1. * * Intelligent electric actuator * *: Explosion proof electric drive head, integrated valve position acquisition, fault diagnosis, limit protection module, with manual emergency operation handwheel, can be manually opened and closed on site in case of power failure or control system failure; Support standard analog and switch signal access, seamlessly integrate with DCS and PLC industrial control systems.

2. * * Connection bracket * *: High strength cast aluminum bracket, strong rigidity, isolates the high temperature of the valve body from conducting to the actuator, protects electric components, and ensures smooth torque transmission.

3. * * Valve stem assembly * *: The valve stem is made of high-temperature resistant stainless steel, which has been quenched and tempered to resist torsion and thermal deformation. It is equipped with multiple packing seals to effectively prevent medium leakage.

4. * * Three eccentric butterfly plate * *: The surface of the butterfly plate is welded with heat-resistant and wear-resistant hard alloy, with a unique three eccentric geometric design. The sealing surface has no continuous friction during the opening and closing process, reducing wear.

5. * * Metal sealing pair * *: A multi-level metal sealing ring combination structure that can adapt to pressure and temperature deformation, ensuring bidirectional sealing performance.

6. * * Clamp type valve body * *: Cast steel valve body, installed by clamp clamping, relying on two flanges of the pipeline to clamp and fix, saving installation space.

Product Advantages

1. * * Three eccentric frictionless seal design**
The axial triple eccentric layout of the valve allows the metal sealing surface to immediately detach from the valve seat when the butterfly plate is opened. During the entire opening and closing process, the sealing surface has almost no sliding friction, greatly reducing wear and significantly extending the service life of the valve. It is suitable for frequent adjustment conditions.

2. High temperature resistance and particle erosion resistance**
Metal hard sealing pair can withstand high temperature steam, high temperature flue gas and other media, and can withstand a small amount of hard particle erosion in the medium, solving the short board of soft sealed butterfly valves that are not resistant to high temperature and are easily scratched and ineffective by particles.

3. * * Bi directional pressure bearing seal**
Unrestricted by the flow direction of the medium, tight sealing can be achieved in both forward and reverse directions. When designing the pipeline system, there is no need to specifically consider the flow direction, and the pipeline layout scheme is more flexible.

4. * * Integrated intelligent electric control**
The actuator is equipped with an intelligent control module that uploads real-time valve position feedback signals and has overload protection and overheating protection functions; According to project requirements, switch type or adjustable type can be configured to accurately regulate the flow rate of pipeline media.

5. * * Clamp type lightweight structure**
Compared to flange butterfly valves, the clamp structure has a smaller volume and lighter weight, significantly reducing the load-bearing capacity of pipeline supports, shortening the on-site installation period, and facilitating disassembly and maintenance in the later stage.

6. * * High security redundancy design**
Equipped with a manual emergency mechanism, in emergency situations such as power outages and instrument failures, operators can manually operate valves on site to ensure the safety and controllability of production pipelines. The product can provide SIL safety certification versions according to project requirements, meeting the requirements of high-risk chemical and power plant safety instrument systems.
