Product features

As the name implies, the pneumatic double clip butterfly valve is used to clamp the butterfly valve between the flanges at both ends of the pipe, and then fix it with a group of bolts through the bolt hole. The valve body of pneumatic clip on butterfly valve is small in volume and relatively thin in thickness, so it is especially suitable for applications where the distance between two ends of the pipe is short or the space is limited. According to the different sealing structure, the pneumatic double clip butterfly valve is divided into soft seal and metal seal. The soft seal butterfly valve is of medium linear structure, which has the advantages of anti-corrosion and zero leakage, while the hard seal butterfly valve is of three eccentric type, which has the advantages of less wear and long service life.

Principle of pneumatic double clip butterfly valve:
 
The pneumatic double clip butterfly valve is driven by the air source of 0.4-0.7mpa compressed air, which drives the valve stem to drive the disc plate to rotate 0-90 degrees in the valve body, so as to achieve the operation control of full opening and full closing of the butterfly valve. According to the working condition requirements, the pneumatic clamp butterfly valve can assemble the valve positioner to the actuator, input 4-20mA related signal, so as to control the opening of butterfly valve disc plate, and realize the accurate adjustment of the percentage of medium pressure, flow, temperature, liquid level and other parameters in the pipeline. Pneumatic double clip butterfly valve can be used not only for local control in industrial automatic control system, but also for remote centralized control. It is one of the system devices preferred in industrial pipeline application.

Installation instructions for pneumatic wafer butterfly valve:
 
Pneumatic clip on butterfly valve can not be used at the end of the pipeline and downstream, because when the downstream flange is disassembled, the clamp valve will fall off. In this case, it is necessary to make a short joint for disassembly. However, the flange butterfly valve does not have the above problems, but the cost will be relatively high.
The purpose of pneumatic clip butterfly valve and flange butterfly valve are the same, they are to switch or adjust the medium flow. The difference between them lies in the installation form. When the pressure is too high, it is generally recommended that the flange butterfly valve is better, and the flange butterfly valve is also recommended for dangerous fluid.
