The difference between the butterfly valve D371F4 and D71F4

One is a handle switch and the other is a turbo switch.

Butterfly valve principle. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve opening and closing or adjusting the valve is called butterfly valve. The butterfly valve is usually less than 90 degrees from open to closed, the butterfly valve and the butterfly rod itself are not self-locking, in order to position the butterfly plate, a worm gear reducer should be installed on the valve stem.

The use of worm gear reducer can not only make the butterfly plate have the ability to lock itself, make the butterfly plate stop in any position, but also improve the operation performance of the valve. The characteristics of the industrial butterfly valve can withstand high temperatures, the applicable pressure range is also high, the valve nominal diameter is large, the valve body is made of carbon steel, and the sealing ring of the valve plate is made of metal ring instead of rubber ring. The large high-temperature butterfly valve is made of steel plate welding, which is mainly used for flue air ducts and gas pipelines of high-temperature medium.

Advantages of butterfly valve Butterfly valve opening and closing is convenient and fast, labor-saving, low fluid resistance, can be operated frequently, simple structure, small size, light weight, can transport mud, the least liquid accumulation at the pipe mouth, low pressure, can achieve good sealing, good adjustment performance, butterfly valve disadvantages.

The butterfly valve uses a small range of pressure and working temperature, poor sealing, during installation, the valve disc should stop at the closed position, the opening position should be determined according to the rotation angle of the butterfly plate, the butterfly valve with a bypass valve, the bypass valve should be opened before opening.

3 refers to the worm gear. The first one is the worm gear butterfly valve, and the second one is the handle butterfly valve.

D373 clamp hard seal butterfly valve is a kind of sealed valve, using three eccentric sealing structure, the valve seat and butterfly plate are almost wear-free, with the tighter and tighter sealing function. The sealing ring is made of stainless steel, which has the dual advantages of metal hard seal and elastic seal, and has excellent sealing performance, corrosion resistance and long service life in the case of low and high temperatures. The sealing surface of the butterfly plate is made of surfacing cobalt-based cemented carbide, which is wear-resistant and has a long service life.

The large-size butterfly plate adopts a quilting structure, which has high strength, large overflow area and small flow resistance. The clamp-on hard seal butterfly valve has a two-way sealing function, which is not limited by the flow direction of the medium during installation, nor is it affected by the spatial position, and can be installed in any direction. The drive can be installed in multiple stations (90° or 180° rotation) for ease of use.

4.Different applications: D343H-16C is used for fluid premature control in industrial fields, such as chemical, water treatment, pharmaceutical, etc.

D71X-16 is more suitable for civil buildings, water supply, heating, air conditioning and other fields. <>

The difference between the butterfly valve D343H-16C and D71X-16.

Butterfly valves D343H-16C and D71X-16 are commonly used butterfly valve models, and their differences are mainly in the following aspects:1Structural form:

The D343H-16C is a centerline butterfly valve, and the D71X-16 is an eccentric butterfly valve. The stem of the centerline butterfly valve coincides with the centerline of the valve disc, and the movement trajectory of the valve disc coincides with the pipeline axis when the valve is opened; The stem of the eccentric butterfly valve does not coincide with the centerline of the free-type valve disc, and the movement trajectory of the valve disc does not overlap with the pipeline axis when the valve is opened. 2.

Applicable occasions: D343H-16C is suitable for medium and low pressure, large diameter pipeline system, D71X-16 is suitable for medium and low pressure, small diameter pipeline system. 3.

Material: The valve body and valve disc of D343H-16C are generally made of cast iron or carbon steel, and the valve body and valve disc of D71X-16 are generally made of stainless steel or cast iron. 4.

Sealing performance: D343H-16C has relatively good sealing performance, which is suitable for occasions with high requirements for tightness; D71X-16 has relatively poor sealing performance and is suitable for occasions where tightness is not required. In general, the differences between D343H-16C and D71X-16 are mainly in terms of structural form, applicable occasions, materials and sealing performance.

The choice of which type of butterfly valve to choose is based on the specific application and requirements.

Summary. The D in the D341F-10P designation stands for Butterfly Valve, while 341F represents the model and series of the butterfly valve. The 10 refers to the nominal pressure class of the butterfly valve, which usually indicates the maximum withstand capacity of the butterfly valve.

The P stands for the butterfly seat seal material, which is polytetrafluoroethylene (PTFE). Therefore, the butterfly valve D341F-10P code means: a butterfly valve with a nominal pressure level of 10, and the seat seal material is PTFE, which belongs to one of the products of the D341F series.

What does the butterfly valve D341F-10P code mean.

I'm still a little confused, can you be more detailed?

The D in the D341F-10P code name stands for Butterfly Valve, and the 341F represents the model and series of the butterfly valve. The 10 refers to the nominal pressure class of the butterfly valve, which usually indicates the maximum withstand capacity of the butterfly valve. The P stands for the butterfly seat seal material, which is polytetrafluoroethylene (PTFE).

Therefore, the butterfly valve D341F-10P code means: a molded butterfly valve with a nominal pressure level of 10, and the seat seal material is PTFE, which belongs to one of the products of the D341F series.
