As we all know, gate valves refer to a kind of valves in which the closure (wedge disc) moves in the vertical direction of the channel axis, and is mainly used as a cutting medium in the pipeline to fully open or close the device. In general, gate valves are not available for regulating flow, but can be applied under low temperature low pressure or high temperature high pressure. The gate valves can be made of different materials depending on the variety of valves. However, gate valves are generally not used in pipelines for transporting media such as mud. The gate valves is composed of a body seat, a plate, a bonnet, a stem, a handle, and a sealing. According to the forms of the sealing terms, the gate valves are often divided into wedge gate valves, parallel disc gate valves, double disc parallel gate valves, wedge double disc gate valves and so on. Among them, the wedge gate valves and parallel disc gate valves are commonly used.
There are many manufacturers of gate valves in China, and their valve sizes are various. At present, the valve manufacturers have sprung up in the market, injecting endless vitality into China's manufacturing industry, and its contribution to the national economy is obvious to the public. The gate valves are mainly used in pulp and paper industry, disposal of sewage, mining, energy and so on. With the acceleration of restructuring the valve industry, the future industry will be the competition between the quality of safer gate valves and the valve brands. The products will develop in the direction of high technology, high parameters, strong corrosion resistance and high service life. We should continue to make full use of existing standards, looking to the future, developing the new standards and systems that can be applied to future development, so as to push the development of gate valve technology into a higher level, and continuously to improve the quality of gate valves. It is believed that China's gate valves will show better development prospects under the large demands.

Wedge gate valve is a kind of gate valves. It is widely used as a gate device in fields of petrochemical, thermal power plants, water vapor pipelines to open or cut off the medium in the pipeline. Most of the wedge gate valves have the characteristics of small fluid resistance, unrestricted flow direction of the medium, simple structures, excellent manufacturing process and short structure length. The wedge gate valves adopt soft graphite packing, with reliable sealing, in light and flexible operation. The driving can be manual, pneumatic, electric and gear transmission. The wedge gate valves have compacted structure, reasonable design, high valve rigidity, smooth passage and small flow coefficient. The surface of sealing is made of stainless steel and hard alloy, and that’s why they have a long service life. The wedge gate valves of Baltic are up to 23, including DN150 Flexible Wedge Gate Valve, DN100 PN63 Flexible Wedge Gate Valve, and DN80 Flexible Wedge Gate Valve. You can choose the specific wedge gate valve as you want. taking API 600 Flexible Wedge Gate Valve as an example, it is used in the fields of Power station, petroleum, tap water engineering, chemical engineering, etc. It can resist high temperature and low temperature, which has the following five characteristics:
1. Body seat and wedge sealing are welded on hard alloy material to improve the erosion resistance and extend the service life of valve.
2. SS+ graphite as bonnet gasket is easy to be replaced.
3. It has a rising stem, OS&Y.
4. The wedge with good sealing performance can slide down flexibly.
5. The stem is threaded, and it does not contact the medium, to avoid possibility of corrosion.

Now, with increasingly large demands of gate valves, China valve manufacturers have try their best to attract valves buyers to pay a ‘visit’ to their products. For example, the wide product promotion is often used for its impressive advertising effects. We can find all sorts of product advertisement showing in the train station, supermarket, streets and other public areas. Compared with wedge gate valves of other companies, Baltic wedge gate valves have the features in more excellent workmanship, absolutely guaranteed quality, friendly price.
