Electric butterfly valve flange

Electric butterfly valve flange DN150 servo control: The built-in servo motor adjusts the rotation angle of the butterfly plate according to the received signal, thereby achieving control of the medium flow rate. Feedback mechanism: The actuator has a built-in position sensor that monitors the rotation angle of the butterfly plate in real time and sends feedback signals back to the control system to form a closed-loop control.

1、 Overview

The flange connection method makes it easy to install and disassemble. This valve is suitable for various media such as water, gas, and oil, and is widely used in fields such as water supply, drainage, petroleum, chemical, and power.

2、 Structure and Composition

The electric butterfly valve flange DN150 mainly consists of the following parts:

Valve body: usually made of cast iron, cast steel or stainless steel materials, with good pressure resistance and corrosion resistance.

Butterfly board: Made of high-strength materials, capable of maintaining stable shape and size under high pressure.

Valve shaft: Made of high-quality steel to ensure that it is not easily deformed during long-term use.

Sealing ring: Made of high temperature resistant and corrosion-resistant rubber or polytetrafluoroethylene material to ensure the sealing performance of the valve.

Electric actuator: Equipped with a built-in servo motor and reducer, it can accurately adjust the valve opening based on control signals.

Flange connectors: including flanges, bolts, and gaskets, used to connect valves to pipelines.

3、 Working principle

The working principle of the DN150 electric butterfly valve flange is as follows:

Signal reception: Electric actuators receive control signals from control systems (such as PLC, DCS, etc.), usually 4-20mA current signals.

Servo control: The built-in servo motor adjusts the rotation angle of the butterfly plate based on the received signal, thereby achieving control of the medium flow rate.

Feedback mechanism: The actuator has a built-in position sensor that monitors the rotation angle of the butterfly plate in real time and sends feedback signals back to the control system to form a closed-loop control.

Sealing protection: The sealing ring ensures that the valve maintains good sealing performance under high pressure, preventing medium leakage.

4、 Characteristics and advantages

Precise control: capable of achieving precise adjustment of medium flow rate, suitable for situations requiring high-precision control.

High pressure resistance: Made of high-strength materials, it can work stably under pressures up to 1.6 MPa.

Easy to operate: Remote operation can be achieved through external control signals without the need for manual intervention.

Compact structure: Integrated design reduces installation space and connecting components, improving system reliability.

Multiple control modes: Supports both switch and adjustment control modes to meet different application requirements.

High safety: equipped with overheat protection, signal loss protection and other functions to ensure the safe operation of the valve in abnormal situations.

5、 Application Fields

Electric butterfly valve flange DN150 is widely used in the following fields:

Water supply system: used to control the water flow in the urban water supply network.

Drainage system: used to control the water flow in sewage treatment plants and rainwater discharge systems.

Petroleum industry: used to control the flow of oil products in oil fields and refineries.

Chemical industry: used to control the flow of acidic, alkaline liquids, gases and other media in chemical plants.

Power industry: used to control the flow of cooling water, steam and other media in power plants.

6、 Maintenance and upkeep
