Ball valves are divided into a variety of materials, and what materials are different.

It is necessary to provide specific parameters in order to**Oh,**Cheap quality must not keep up, and if you want hard quality, you can't paint cheap.

In December 2019, the market wholesale ** was around 30.

Ball valves are generally affected by factors such as material, size and size, we take a DN25 stainless steel ball valve as an example to remove the brand value. And if it is hygienic, ** will be higher. If you need a more accurate ball valve**, you can ask Wenzhou Keda valve.

Expanded Extension Information:

Advantages of ball valves. It is easy to operate, quick to open and close, and only needs to rotate 90° from full open to full closed, which is convenient for long-distance control.

It is easy to maintain, the structure of the ball valve is simple, the sealing ring is generally movable, and it is more convenient to disassemble and replace. When fully open or fully closed in the bridge state, the sealing surface of the ball and the valve seat is isolated from the medium, and when the medium passes, it will not cause the erosion of the sealing surface of the valve.

It is suitable for Fan Minyouyuan, with a diameter from a few millimeters to several meters, and can be applied from high vacuum to high pressure. Since the ball valve is wipeable during opening and closing, it can be used in media with suspended solids.

How much is a pneumatic ball digging valve?

As follows: pneumatic ball valve is a ball valve with a pneumatic actuator, the execution speed of the pneumatic actuator is relatively fast, and the fast switching speed is seconds, so it is usually called pneumatic quick shut-off ball valve. Pneumatic ball valves are usually equipped with a variety of accessories, such as solenoid valves, air source treatment triplets, limit switches, controllers, control boxes, etc., to achieve local control and remote centralized control, and the valve can be controlled in the control room, without running to the scene to manually control, which saves human resources and time and safety to a large extent.

The aspects that need to be paid attention to in the selection of pneumatic ball valves are:

1. The working principle of pneumatic ball valve is to rotate the valve core to make the valve unblocked or occluded. The ball valve switch is lightweight, small in size, can be made into a large diameter, reliable sealing, simple structure, easy maintenance, sealing blind surface and spherical surface are often in a closed state, not easy to be eroded by the medium, and have been widely used in various industries.

2. Pneumatic ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of the medium.

3. Pneumatic ball valve is a relatively new type of ball valve, which has some advantages unique to its own structure, such as frictionless switch, sealing is not easy to wear, and the opening and closing torque is small. This reduces the size of the actuator. Equipped with a multi-turn electric actuator, it can realize the adjustment and strict cutting of the medium.

Suzhou Neway, hand in hand with Shanghai Guanlong, Shanghai Qizhong, Sanhua, Chaoda, Shentong, Su Valve, Nanfang, Jiang Yixian Qi, Yaozi. You can refer to it, and the debate school thinks that the quality and service of these manufacturers are good.

Shanghai Guanlong Valve, Shanghai Qizhong Valve, Suzhou Neway Valve, these are of good quality.

Personally, I think the following are some of the more well-known and influential valve brand manufacturers in the market, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Chaoda, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. It should be noted that the above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as the change of the market's leading letter, the size of the competition pattern, and the stability of product quality. For example, Qizhong Company is mainly engaged in the production, sales and service of HVAC valves, electric valves, pneumatic valves, chemical valves, metallurgical valves, water supply and drainage system valves and fire valves, and is committed to providing customers with a full set of pipeline valve solutions.

Qizhong valve will adhere to the development concept of quality determines strength, carry forward the spirit of striving for progress, unity and hard work, adhere to the business policy of integrity-based, innovation, forge ahead, and steady development, vigorously promote technological innovation, capital operation, and international expansion. The company's high-end products include: titanium and titanium alloys, zirconium alloys, nickel and nickel alloys, hastelloy, monel alloys, inconel nickel alloys, nickel aluminum bronze, alloy 20, 904L, duplex steel, tantalum and other special material valves and stainless steel valves.

Our company has the production of O-type ball valves and V-type ball valves. In terms of different materials, different seals. Each ** is different.

But overall. O-type ball valves are a little more expensive, and O-type ball valves are heavier than V-type ball valves with the same canopy diameter. And the materials are also a little more expensive.

So. According to the manufacturing experience of our factory. O-type ball valves are more expensive than V-type ball valves.

However, the scope of application is not the same.

The V-type ball valve is a ball valve with a special design of collapse width, and the shape of the ball is presented"v"It can be used to control the flow of viscous liquids, media, high-concentration suspensions, fiber-leucin, etc. Because the design of the V-shaped sphere allows it to effectively scrape off the residual material in the pipeline during the opening and closing process, thus avoiding the accumulation and contamination of the medium, it is suitable for chemical, pharmaceutical, food processing and other industries.

The shape of the ball body of the O-type ball valve presents an "O" shape, which has good sealing performance, and is suitable for high viscosity, high pressure difference and strong corrosive media, such as petroleum, chemical, natural gas and other industries.

In general, the choice of which ball valve to use needs to be considered according to the nature of the medium, process requirements, operation mode and environmental factors.

Haidun's V-shaped ball valve.

V-Ball Valves are expensive. According to the relevant information of the sock inquiry, the V-shaped ball valve ** is about 400 yuan to 600 yuan and lost. O-type ball valve ** is about 100 yuan to 400 yuan, so it is more expensive V-type ball valve.

Ball valve models generally have their own set of model lists for each manufacturer, but there are also standard models for reference.
