Applications and Uses of Farpro Gate Valve Manufacturer

Water Treatment Project

What Are The Functions of Gate Valves in Water Treatment Project

According to Farpro Gate Valve Manufacturer's statistics, it was found that different types of valves are used for each level of general wastewater treatment.

- The first step, primary treatment, removes solid pollutants in suspension, and most physical treatment methods meet the requirements of treatment. After primary treatment, the removal rate of BOD is generally around 30%.
- The second step, the need to remove the colloid and dissolved organic pollutants in the sewage (BOD, COD substances), the removal rate of 90%, so that organic pollutants meet the discharge standards, suspended matter removal rate to 95%.
- The third step, the main methods include biological denitrification and phosphorus removal, coagulation and sedimentation, sand filtration, activated carbon adsorption, ion exchange and electroosmosis. The valves needed here are butterfly valve, tolózár, golyóscsap, ellenőrizd a szelepet, rubber soft joint, stb.

Power Generation Industry​

Power Generation Industry

Farpro Gate Valve manufacturer believes that power plant applications put piping and valves under tremendous stress, so valves need robust materials and designs to handle the multiple tests of circulation, temperature and pressure.

Many power plants use fossil fuels and high-speed turbines to generate electricity, where gate valves are the primary equipment controlling the opening/closing of most power plants. Of course, other valves are sometimes used here as well, such as Y-shaped globe valves. Továbbá, high performance ball valves are widely used in the power industry.

In addition to the main steam valves, power plants have many auxiliary pipelines. These auxiliary pipelines consist of a wide variety of globe valves, pillangószelepek, ellenőrizd a szelepeket, golyóscsapok, and gate valves.

Metallurgical-Steel Industry

Metallurgical / Steel Manufacturers

Farpro gate valves are widely used in metallurgical iron and steel engineering in the raw material feeding system, dosing system, ironmaking coal injection system.

At present, the common gate valves in metallurgical steel manufacturers are mainly knife gate valves, pneumatic gate valves, pillangószelepek, golyóscsapok, stb.

Pulp And Paper Industry

Pulp And Paper Suppliers and Manufacturers

The paper production process is divided into two parts: pulping and papermaking. The wastewater produced in the process, after treatment to meet the relevant national emission standards, are indispensable for the participation of various types of valves, beleértve a tolózárakat is.

According to Farpro gate valve manufacturer's years of valve experience, the main media encountered in the paper manufacturer are: slurry, gőz, víz, sewage and black liquor and other such media. Control valves for production media do not need to be specifically considered for high temperature, high pressure, erős korrózió, explosion-proof and other factors.

Gate valves widely used in other industries are also applicable to the control of water, gőz, other gases in the paper industry. For the control of pulp, black liquor, etc., rotary V-regulating ball valves, О-control ball valves and control disc valves are commonly used.

Chemical Processing

Chemical Processing

The gate valve stem produced by Farpro manufacturer has open stem and concealed stem. In the chemical industry, open stem gate valves are suitable for corrosive media in chemical engineering basically use open stem gate valves. Concealed stem gate valves are mainly used on waterways mostly for low pressure, non-corrosive media such as some cast iron and copper valves.

The structure form of the Farpro gate includes wedge gate and parallel gate gate valve. Wedge gate valve has single gate and double gate. Parallel type gate is mostly used in oil and gas transmission system, it is not commonly used in chemical installations.

Oil & Gas Marine Industrial

Oil & Gas / Marine Industry

The oil and gas industry provides a broad market for valve manufacturers, particularly in gate and ball valves, while the performance requirements for valves are increasing.

Farpro has concluded, based on global sales and data, that the demand for valves in the global oil and gas extraction industry and transportation industry continues to grow. This demand has led to the oil and gas industry's quest for deeper drilling pipelines and lower production costs, so technicians are taking greater care in selecting quality valve equipment and hardware.

Upstream, valves are used to control the flow of oil, from high-pressure injection systems to throttle blowout preventers.

In the midstream section where storage and transportation of oil and gas takes place, valves are used to protect equipment and control the flow of product. Since the entire system should be kept at low temperatures to convert gas to liquid, oil and natural engineering requires valve manufacturers to produce valves and fittings that are durable even at low temperatures.

Downstream, Farpro sees more challenges in the refining process of crude oil. The growing segmentation of the market provides many high-tech needs for the petrochemical industry, which is why there is a need for high-precision, high-quality valve production and design.
