By replacing the valve plate sealing ring, O-ring, butterfly plate, shaft and other materials, it can be applied to various media and different temperatures. The automatic control equipment for valves is equipped with electric actuators or double acting pneumatic actuators, which can achieve both automatic and manual opening and closing functions.

Features:

1.4529 desulfurization butterfly valve 2507 flue gas desulfurization butterfly valve desulfurization slurry butterfly valve is specially designed for use in desulfurization and denitrification projects. It not only meets the corrosion and wear of the valve caused by desulfurization slurry, but also ensures that other components are not corroded by limestone (or lime paste) slurry. By replacing the valve plate sealing ring, O-ring, butterfly plate, shaft and other materials, it can be applied to various media and different temperatures. Valve automatic control equipment is equipped with electric actuators or double acting pneumatic actuators, which can achieve dual opening and closing functions of automatic and manual. The valve seat design of the desulfurization butterfly valve separates the valve body from the fluid medium. Compared with other similar valves, it has a better way of securing the valve seat, quick on-site replacement of the valve seat, zero valve leakage, and low friction. When the diameter is greater than DN200, use a worm gear drive for easier opening.

2507 desulfurization clamp butterfly valve1.4529 desulfurization butterfly valve for flue gas desulfurization and denitrification is suitable for the lime gypsum desulfurization process, and is suitable for corrosive media containing particulate matter such as limestone slurry and gypsum slurry. Optional driving devices: handle, worm gear, electric switch, electric adjustment, pneumatic switch, pneumatic adjustment.

1.4529Desulfurization butterfly valveIt is necessary to meet several requirements such as corrosion, wear, flow rate, and temperature, and all types of mineral fuels contain sulfur. Especially coal, after combustion, generates a large amount of SO2, which seriously pollutes the air. The most effective way to control pollution is flue gas desulfurization. The 2507 plate desulfurization butterfly valve has a simple structure, small volume, and light weight. Rotate the handle 90 ° to easily open and close the valve, and keep the valve at the desired opening angle.

The driving mode can be selected from handle, turbine, electric, and pneumatic

Including China, the most widely used method currently is "lime (limestone) gypsum"Wet desulfurization technologyIn this process system, multiple corrosive media are involved and contain particulate materials, which cause strong corrosion and wear to the equipment. Therefore, there are special requirements for the material and structural form of the valve. In the late 1980s, when China introduced foreign desulfurization technology on a large scale, the valve body of imported butterfly valves was lined with EPDM rubber, and the butterfly plate and valve stem were made of Hastelloy alloy material. Due to its high price, more and more users have adopted duplex stainless steel butterfly plates. Duplex stainless steel combines the characteristics of austenitic stainless steel and ferritic stainless steel, combining the excellent toughness and weldability of austenitic stainless steel with the high strength and chloride stress corrosion resistance of ferritic stainless steel. In the late 1980s, it developed rapidly as a weldable structural material and has become an important type of stainless steel. Compared with other types of stainless steel, it has the following characteristics:

1. Molybdenum containing bidirectional stainless steel has good resistance to chloride stress corrosion under low stress, and can replace austenitic 18-8 stainless steel that is prone to stress corrosion cracking under this medium condition;

2. Molybdenum containing bidirectional stainless steel has good resistance to pitting corrosion. When the equivalent resistance to pitting corrosion (PRE) is the same, the critical pitting potential of bidirectional stainless steel is similar to that of austenitic stainless steel. The pitting corrosion resistance of bidirectional stainless steel containing 18% Gr is comparable to AISI 316L. The pitting and crevice corrosion resistance of high chromium bidirectional stainless steel containing 25% Cr, especially nitrogen, exceeds that of AISI 316L;

3. Has good corrosion fatigue and wear resistance;

4. Good weldability, no need for heat treatment after welding, and the welded joint has good corrosion resistance;

5. Compared to Hastelloy alloy, its price is much lower. Steel grade chromium (Cr) nickel (Ni) molybdenum (Mo) nitrogen (N) carbon (C) 254SMO 20 18

The outstanding feature of this type of steel is its excellent corrosion resistance in chloride environments, including resistance to pitting corrosion, crevice corrosion, stress corrosion, and general corrosion. It also has good corrosion resistance in many reducing acid media. In addition, due to its high nitrogen content, this type of steel has higher strength than commonly used austenitic stainless steels. This steel grade is mainly used in seawater equipment, bleaching equipment in pulp and paper industry, valve components in flue gas desulfurization system, as well as containers and pipelines for processing and transporting media containing halogen compounds. These types of super austenitic stainless steels generally have similar performance. As the nickel (Ni) content increases, the performance slightly improves, but the price also increases accordingly.

Installation precautions:

1. The standard for pipeline clamp flanges must be consistent with the butterfly valve standard, and it is recommended to use butterfly valve flanges for clamp connection flanges;

2. Before use and installation, check whether the operating conditions are consistent with the performance of this butterfly valve;

3. Before installation, the valve cavity and sealing surface should be cleaned to prevent any dirt or debris from adhering;

4. The protruding valve body end faces at both ends of the valve seat serve as flange gaskets, and there is no need to add additional gaskets during the installation of butterfly valves;

5. This butterfly valve can be installed on horizontal, vertical, and any angle of pipeline, and can be used in both directions;

6. Butterfly valves shall not be installed at the corners of pipelines and shall not be installed upside down;

7. During installation, the butterfly valve must be in the closed position to ensure that the butterfly plate does not collide with the pipeline flange, etc;

8. Confirm that the flange welding is correct. After installing the butterfly valve, it is not allowed to weld the flange again to avoid burning the rubber parts and anti-corrosion coating;

9. If the butterfly valve experiences abnormal opening and closing, the cause should be identified, the fault should be eliminated, and methods such as knocking, smashing, prying, and using handle extension rods to forcibly open and close should not be used.
