Product Description
General Introduction
The signal butterfly valve is a kind of valve device widely used in various pipeline systems. It is mainly used to control the on - off and flow of media in the pipeline, and can also provide signal feedback to monitor the valve's opening and closing status.
Working Principle
The signal butterfly valve works by rotating the disc around the valve shaft. When the disc is rotated to a certain angle, it can block or allow the passage of the medium in the pipeline, thereby achieving the control of the flow. The signal feedback mechanism is usually composed of a microswitch or other sensing device. When the valve is opened or closed, the sensing device will send out an electrical signal to inform the control system of the valve's status.
Main Components
- Valve Body: Usually made of materials such as cast iron, carbon steel, or stainless steel, which can withstand different working pressures and temperatures. It provides the basic structure and connection interface for the valve.
- Disc: The part that directly controls the flow of the medium. It is usually made of metal or plastic and is connected to the valve shaft. It rotates within the valve body to open or close the passage.
- Valve Shaft: Transmits the torque from the actuator to the disc to drive the disc to rotate. It needs to have sufficient strength and stability to ensure the normal operation of the valve.
- Sealing Ring: Installed between the disc and the valve body, it plays a role in sealing to prevent the medium from leaking. The material of the sealing ring is selected according to the characteristics of the medium and the working temperature, such as NBR, FKM, or silicone rubber.
- Actuator: Can be manual, electric, pneumatic, or hydraulic. It provides the power to drive the valve shaft to rotate and control the opening and closing of the valve. The signal butterfly valve is usually equipped with a manual actuator as standard, and other types of actuators can be selected according to specific needs.
- Signal Feedback Device: As mentioned above, it is used to send out electrical signals to reflect the opening and closing status of the valve. It is usually composed of a microswitch, a potentiometer, or other sensors.
Technical Parameters
- Working Pressure: Commonly ranges from 0.6MPa to 2.5MPa. Different pressure levels are suitable for different pipeline systems. For example, 0.6MPa is suitable for low - pressure water supply and drainage systems, while 2.5MPa is suitable for high - pressure occasions such as some chemical production pipelines.
- Working Temperature: The temperature range varies depending on the material of the valve and the sealing material. General - purpose valves are suitable for - 10ºC - 80ºC, high - temperature - resistant valves can reach 120ºC - 150ºC, and low - temperature - resistant valves can work at - 40ºC or even lower temperatures.
- Nominal Diameter: Usually ranges from DN40 to DN600. Common specifications include DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200, etc. The larger the nominal diameter, the larger the flow capacity of the valve.

Price Range
The price of the signal butterfly valve varies depending on many factors, including specifications, materials, brands, and connection methods. Taking the common DN100 - DN150 specifications as an example, the approximate price range is as follows:
Ductile Iron Material: The price of the wafer - type ductile iron signal butterfly valve is usually about 40 - 100 RMB for DN100. For example, on the ****** platform, the quotation of the XD371X - 16Q fire - protection signal butterfly valve DN100 of some manufacturers is as low as 48 RMB. The price of DN150 is generally about 80 - 200 RMB. For some turbine - grooved signal butterfly valves XD381X - 16Q, the price of DN150 may be between 85 - 165 RMB.
Carbon Steel Material: The price of the carbon - steel - flange signal butterfly valve is relatively higher than that of the ductile - iron - material valve. The price of DN100 carbon - steel - flange signal butterfly valve is about 80 - 200 RMB, and the price of DN150 is usually about 100 - 300 RMB.
Stainless Steel Material: The price of the stainless - steel signal butterfly valve is higher. The price of the DN100 stainless - steel 304 grooved signal butterfly valve is about 99 - 300 RMB, and the price of DN150 may be about 150 - 500 RMB. If it is a higher - end stainless - steel material or a stainless - steel signal butterfly valve with special requirements, the price will be even higher.
Special Brands or Certified Products: The price of signal butterfly valves with special certifications such as FM certification is relatively high. For example, the price of the ZSFD150 grooved signal butterfly valve of Shanghai Jindun Fire - fighting Equipment Co., Ltd. with FM certification is 1680 RMB for 1 - 10 pieces, and 1590 RMB for 11 pieces and above.
The price of large - diameter signal butterfly valves will be correspondingly higher, and the prices of electrically - driven, pneumatically - driven, and other types of signal butterfly valves are also much higher than those of manual ones.
