Stainless Steel Pneumatic Butterfly Valve

1. Compact structure: low volume, light weight and easy maintenance

2. Smooth flow channel: low flow resistance, low pressure drop and high flow

3. Three-eccentric multi-level compound seal butterfly valve: It uses the unique cam effect, so that during the valve's 90 ˇtravel the seat is totally disengaged from the disc seal ring without any friction.

Three-eccentric soft seal butterfly valve: The sealing pair is made of integral PTFE materials, which are suitable for applications with high medium cleanliness, frequent valve on-off and high requirements for sealing pair corrosion resistance. Especially it can ensure that its service life is basically the same as that of the pipe in the thermal system.

Three-eccentric metal seal butterfly valve: The sealing pair adopts a full metal seal structure. The sealing pair adopts a "hard-contact-hard" structure as shown in figure 1 pneumatic three-eccentric butterfly valve. The seal has a long service life. It is suitable for service conditions where the medium working temperature is extreme, the erosion is severe and there is the occurrence of "crystallization".

4. Strong anti-wear performance: The disc adopts a three-eccentric structure and the sealing face is subject to hard alloy overlaying welding with good anti-wear performance.

5. Valve flow characteristics: Approximate equal percentage. Control and shut-off can be realized.

And the process, testing, packaging and customer feedback, etc.

2. What is the CHVM detachable gooseneck trailer used for?

Because lowboy trailer has a low center of gravity and a long cargo table, it can transport a lot of goods. Such as some large machinery and equipment, such as pile drivers, large rotary drills, large excavators, and large bulldozers, have very high centers of gravity due to their very high height.

As you can see, the heavy duty lowboy trailer can transport ultra-high and medium sized equipment and machine.

5. CHVM detachable gooseneck lowboy trailer package:

To prevent the extendable gooseneck trailer paint from being corroded by seawater, we spray a layer of wax on the surface of the lowboy trailer before shipping, and then seal it with a waterproof rain cloth.

6. What is the difference between lowbed trailer and detachable gooseneck lowboy trailer?

Loading with lowbed trailers, you cannot lower it any further. That means you can`t work without auxiliary equipment for lifting cargo and loading it onto the trailer. For that matter, it will limit you to the type of cargo that you can carry on lowbed trailers.

With RGN trailers, you don`t have to be worried about this since you can almost carry all types of cargo. Characteristics of detachable gooseneck lowboy trailer are that it can be detached from the front unlike with a Lowbed Semi Trailer. This feature has been provided in an RGN trailer to enhance loading and offloading of cargo. The user has an easy time during such occasions. This is unlike for a lowbed Semi Trailer that load the cargo from rear. It is possible to carry heavy motorized machinery since the trailer can be lowered to its ramp. The appropriate trailer to choose depends on the cargo type that you want to handle.

Owing to these notable characteristics, the RGN trailer is easy to load. This capability enhances the efficiency of the detachable gooseneck lowboy trailer over that of the lowbed trailer.

7. CHVM detachable gooseneck lowboy trailer feedback from Guinea customer

Passed all aspects of weight test and connection test. We packed the 3 axle lowboy trailer with rain cloth to prevent moisture. We also provide some spare parts to our customers.

Recently, we received feedback from our customers and there is no doubt that the customer is satisfied with our semi trailer. Most importantly, he is willing to introduce his good friends to order and buy semi trailer from us.
