Precautions when buying Butterfly valves
Recommendations for purchasing butterfly valves
Why choose XinHui Butterfly valves?
Cheap
The butterfly valves we produce have competitive prices, which are cheap without cutting corners and materials, strictly in accordance with production standards, especially for large-diameter butterfly valves;
Good adjustment performance
The butterfly valve we produce has good regulation performance, when it is opened, the flow resistance is small, and it has the characteristics of proportional flow control. It can be used for the regulation process control of low pressure and large diameter conditions.
Simple structure
We produce the most practical butterfly valve with the most reasonable design and simple structure. It has the advantages of small size, light weight, saving consumables without sacrificing quality
Strong sealing performance
Through years of efforts, Xinhui Valve has reformed the sealing performance of the butterfly valve, improved the sealing characteristics of the butterfly valve, and the soft-sealed butterfly valve can achieve zero leakage.
Easy to operate
It can be opened or closed only by rotating 90°, so the opening and closing speed is fast and easy to operate. It is worth mentioning that the valves we produce have many opening and closing times and long service life.
Easy maintenance and installation
The valve body has the function of valve seat, and can use the throttling flushing to flush the inner wall of the valve body, which has a "self-cleaning" effect and can be used for unclean media. And the installation space is small and the maintenance is easy.

D341F Fluorine Lined Flanged Butterfly Valve - Recommended for Chemical Industry
As a component used to realize the on-off and flow control of the pipeline system, the fluorine-lined flange butterfly valve is widely used in the petroleum field. Suitable for various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidants at -50℃~150℃, FEP flange lined fluorine butterfly valve is suitable for various concentrations of strong alkali organic solvents And other corrosive gas, liquid medium pipeline use.
HBD741X(H) Hydraulic Controlled Slow Closing Check Butterfly Valve-Recommended for power station industry
The hydraulically controlled slow-closing check butterfly valve is also a relatively good pipeline control equipment in China. It is mainly installed at the turbine inlet of the hydropower station industry and used as the turbine inlet valve. Therefore, since the hydraulically controlled slow-closing check butterfly valve has been developed, it has replaced the functions of the gate valve and the check valve. Through the preset opening and closing procedures, in this way, the reliable cut-off of the pipeline is realized, the water hammer of the pipeline is effectively eliminated, and the safety of the pipeline system is protected.
D363H Butt Welded Metal Hard Seat Butterfly Valve-Recommended for metallurgical industry
D363H butt welding hard sealing butterfly valve is widely used in metallurgy, electric power, petrochemical industry, water supply and drainage and municipal construction and other industrial pipelines with medium temperature ≤425℃. It adopts precise J-shaped elastic sealing ring and triple eccentric multi-layer metal hard sealing structure, which is used for regulating flow and load-cutting fluid. The valve seat and disc sealing surface are made of different hardness and stainless steel, which have good corrosion resistance. Long life, the valve has bidirectional sealing function
NKD943X double seal vacuum butterfly valve-recommended for chemical and pharmaceutical industries
NKD343X double-sealed vacuum butterfly valve is a new generation of high-tech products successfully developed by our company in combination with new vacuum technology standards at home and abroad.
The valve structure is designed as: double butterfly plate, double sealing seat, three-dimensional eccentric locking structure, cobalt-based hard alloy surfacing on the sealing surface of the valve body, and the sealing ring is made of temperature-resistant, corrosion-resistant rubber and fluorine rubber pressure plate firmly sealed Pressed on the butterfly plate can be removed and replaced for easy maintenance
Top Entry Type Two-way High Pressure Metal Hard Seal Butterfly Valve-Recommended for Petroleum Industry
The top-mounted two-way high-pressure metal hard-sealed butterfly valve has the advantages of simple structure, low cost, convenient maintenance, and does not affect the normal operation of the pipeline system during maintenance.

Butterfly Valves: Ultimate Guide
Why is it called a butterfly valve?
Butterfly valves get their name from the shape and movement of the valve plug. The valve plug is butterfly-shaped, and the valve stem passes through the valve plug, reminiscent of a butterfly. To stop fluid flow, the valve disc rotates 90 degrees on the normal channel where the pipe runs, like butterfly wings.
Is a butterfly valve a control valve?
What are the types of butterfly valves?
Butterfly valves can be divided into segment type and adjustment type according to their use, and can be divided into midline type, single eccentric, double eccentric and triple eccentric butterfly valves according to their structure. .
What is the difference between a ball valve and a butterfly valve?
1- For the first tail the method of shutting off the ball valve and the throttle valve is different as the ball valve blocks the channel through the ball to realize the interruption flow of the pipeline. The butterfly valve relies on the wing of the butterfly and the pipeline will not flow if it is stretched and sealed.
2- The second important difference is that the structure of the ball valve and the valve are not the same. The ball valve consists of the valve body, the valve core and the valve stem, and only some parts are visible in the body. Inevce, the butterfly valve consists of valve body, valve seat, valve plate and valve stem and all accessories are visible. Therefore, it can be seen that the sealing performance of the butterfly valve is not as good as that of the ball valve. Butterfly valves are also divided into soft seals and hard seals. The structure of the butterfly valve is relatively simple, it can only be used in low pressure environment, the maximum pressure is only 64kg. Compared with the ball valve, the ball valve can reach up to about 100 kilograms.
3- The third difference lies in the operating system of the ball valve and the butterfly valve. The ball valve has a 90 degree rotation action, precisely because its opening and closing part is a ball, it can only be opened or closed by operating a 90 degree rotation, which is the most suitable for switching. But now the V-shaped ball valve can be used to regulate or control the flow. The butterfly valve is a type of valve that uses a disc type opening and closing element to oscillate approximately 90 ° to open, close or regulate the flow of fluid. It has a good flow regulating function and is one of the fastest growing valve varieties.
What is the difference between gate valve and butterfly valve?
PRINCIPLE
What are the advantages of a butterfly valve?
Butterfly valves are lighter, smaller and lighter than other types of control valves and are the best choice for regulating flow in many applications. Traditionally, standard butterfly valves have been used for automatic on/off applications and they are well suited for this role. However, some engineers consider them unacceptable when regulating flow in closed-loop systems.
