DINKONDA GLOBAL Power Plants Special DN50-DN500 WCB Cast Steel Super Corrosive Medium Lining PTFE Automatic Control Valve Flange Electric Butterfly Valve

DINKONDA GLOBAL Power Plants Special DN50-DN500 WCB Cast Steel Super Corrosive Medium Lining PTFE Automatic Control Valve Flange Electric Butterfly Valve

Product Overview

Electric fluorine lined butterfly valve is a self-control valve designed specifically for strong corrosion conditions. The core sealing unit of the valve adopts a PTFE fully lined butterfly plate with a spherical sealing surface, combined with a split valve body structure. It relies on an electric actuator to drive the butterfly plate to rotate 90 °, and has dual functions of fast cutting and flow regulation. The unique valve shaft isolation design ensures that the valve stem does not come into contact with corrosive media inside the pipeline, fundamentally preventing shaft corrosion failure. It is suitable for various strong acid and alkali, strong oxidizing medium pipelines and is the core control equipment of chemical anti-corrosion automation pipelines.

Structural Composition

1. * * Intelligent electric actuator * *: Equipped with a multifunctional electric drive device, it integrates valve position feedback and overload protection functions, comes with a manual emergency handwheel, and can be manually operated on site in case of power failure; Supports two control modes: switch type and adjustment type, can be connected to 4-20mA standard signals, and can be connected to DCS system for remote automation control.

2. * * Connection bracket * *: Anti corrosion type connection bracket, isolates medium corrosion and heat conduction, stably transfers driving torque, and protects precision components inside the electric actuator.

3. * * Valve stem assembly * *: High strength anti-corrosion valve stem, relying on the rotating base surface between the butterfly plate and the valve seat+fluororubber combination sealing structure to achieve medium isolation. * * The valve stem does not contact the fluid inside the pipe * *, avoiding strong acid and alkali erosion of the valve stem.

4. * * Fluorine lined butterfly plate * *: The butterfly plate substrate is coated with polytetrafluoroethylene as a whole, with a spherical sealing surface. During rotation, it adheres to the fluorine lined valve seat, with uniform sealing contact and light opening and closing torque.

5. * * Split valve body * *: The valve body adopts a split casting structure, and the inner wall of the valve body flow channel is fully lined with polytetrafluoroethylene, which is resistant to medium penetration, stable under pressure, and easy to disassemble and maintain.

6. * * Fluorine lined valve seat * *: PTFE lined valve seat, resistant to strong corrosion, excellent elastic compensation performance, ensuring tight sealing within the full pressure difference range.

Product Features

1. * * Spherical fluorine lined sealing structure, easy to open and close**
The butterfly plate adopts a spherical sealing surface and PTFE integral lining design, with the spherical surface fitting the valve seat, low rotational friction resistance, and easy valve operation; The sealing surface is evenly adhered, and the closed state can achieve tight and zero leakage, meeting strict sealing requirements.

2. * * Valve stem medium isolation design, high anti-corrosion reliability**
By relying on the rotating base surface of the butterfly plate and valve seat combined with fluororubber sealing, the valve stem is completely isolated from the highly corrosive medium inside the pipeline, solving the common problem of corrosion and leakage of ordinary butterfly valve stems and greatly extending the overall service life of the valve.

3. * * Split valve body, easy to maintain**
The valve body adopts a split structure, which allows for maintenance and replacement of lining parts without the need to dismantle the valve as a whole, reducing the difficulty of equipment maintenance and downtime costs under strong corrosion conditions.

4. * * Fully lined with PTFE, resistant to strong corrosion**
All overcurrent areas are lined with polytetrafluoroethylene, which can withstand various highly corrosive liquid and gas media such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine gas, strong alkali, aqua regia, etc., and is suitable for the vast majority of highly corrosive chemical process pipelines.

5. * * One valve for multiple purposes, balancing cutting and regulating**
It can be used as a shut-off valve to quickly connect and disconnect pipeline media, as well as a regulating valve to stably adjust the flow rate of gas and liquid (including steam) media, suitable for working conditions that require reliable sealing and continuous regulation.

6. * * Dual operation guarantee of electric and manual**
Electric mode enables remote centralized automatic control; Equipped with a manual operating mechanism, in emergency situations such as power outages and control system failures, valves can be manually operated on site to ensure pipeline safety.
