Applications:

Water and Wastewater Systems:

Gate valves are commonly used in water systems and wastewater treatment plants. They can be used to regulate the flow of water, allowing it to move smoothly at appropriate speeds and allow sections of the pipeline to be isolated when necessary.

Oil and Gas Industry:

Gate valves are employed in several areas of the oil and gas sector, such as upstream, midstream, and downstream operations. In these sectors, they are responsible for controlling the flow of crude oil, natural gas, and other petroleum products, thus guaranteeing safe and efficient operation.

Power Generation Plants:

Gate valves are extremely important in power plants, such as thermal, nuclear, and hydroelectric units. They are utilized to manage the flow of steam, cooling water, and other fluids, helping to maintain the system's performance and safety.

Chemical and Petrochemical Industries:

Gate valves are also commonplace in chemical processing plants and refineries. Here, they are applied to manage corrosive and hazardous fluids, and also offer dependable shut-off capabilities for maintenance and emergency situations.

Mining and Minerals Processing:

Gate valves are used in mining activities and mineral processing plants for dealing with abrasive media. They provide isolation and management of fluid flows in pipelines transporting minerals, ores, and tailings.

HVAC Systems:

In HVAC systems, gate valves are necessary to regulate the flow of water and refrigerants. They are important to maintain accurate pressure and temperature regulation in buildings or industrial facilities.

Firefighting Systems:

Gate valves are integrated into fire protection systems, and allow water supply to be quickly terminated in emergency situations. They are considered to be a dependable and prompt form of controlling water flow to sprinkler systems and firefighting equipment.

Pharmaceuticals and Food Processing:

It is widely known that gate valves with special design features are necessary in the pharmaceutical and food processing industries. These designs allow the valves to efficiently control fluids while meeting the high hygiene standards of the industry.

FAQ:

 

1. What are the main applications of this valve?

This valve is mainly used for isolation service in water supply networks, irrigation systems, fire protection systems, and general industrial applications involving water.

2. What are the advantages of a ductile iron body?

Ductile iron provides strength, impact and corrosion resistance, and ability to withstand high pressures compared to cast iron or steel. It has a long service life.

3. How does the flexible wedge ensure good sealing?

The ductile iron wedge flexes and adapts to the rubber seat ring to achieve tight shut-off without jamming the valve. This provides drop-tight shutoff.

4. When should the rubber seat be replaced?

The nitrile seat should be replaced if there is observed leakage through the valve in closed position at full rated pressure. Replacing the seat restores tight shutoff.

5. How often should re-greasing of the stem be done?

The stem and packing box should be re-greased every 6 months to prevent drying and ensure smooth operations. Use waterproof valve grease. Over-greasing should be avoided.

6. How to ensure the Flange gate valve does not get jammed?

Regularly operate the valve through its full range. Ensure there is no debris or scales in the pipeline. Lubricate internal parts. Do not force the valve open when jammed.
