To replace an air vent valve for water system, first disconnect the existing valve from the water line. Following that, disassemble the air vent valve and replace the O-ring and rubber washer. Replace the new air vent valve clockwise after applying Teflon tape to the threads. A small, circular device that allows water to exit while preventing air from entering is known as an air vent valve. It comes in a variety of styles and materials.
When water begins to flow through the pipe, air within the system is pushed toward the apco air vent valve. This air reduces the water pipeline's effective cross-sectional area, resulting in lower flow and higher head loss. It may also cause corrosion and water hammer. As a result, it is critical to install an air vent valve in your water line.
Air can accumulate at a high point in the pipe in some systems. If there is no flow of water, the air pocket will expand. Using an air release valve will help to prevent this problem and keep your system running smoothly. While these valves are costly, they can save you a significant amount of money in the long run.
The volume of air vented through an air release valve is proportional to the working pressure in the location of the valve. As a result, the higher the working pressure, the more air that can be vented through the valve. As a result, it is critical to select the appropriate size air vent valve for the piping system. If the system pressure is 100 psi, a 1-inch valve with a 5/16-inch orifice will suffice.
All valves are 100% hydrostatically tested at the AFC Valve factory. In general, the test pressure is 1.5 * for pressure ratings in the shell test and 1.1 * for pressure ratings in the seat test. We believe that all valves such as combination air valve within the water system can be serviced using the testes valve. The standard that we used was EN12266. For products that meet UL and FM standards, we will follow the UL/FM procedure.
The standard manufacturing process tightly controls each manufacturing step. AFC's quality management system oversees all stages of production, from castings to machining, coatings to assembling, testing, packing, and packing. Process control can lead to a high-quality product including auto air release valve.
Our team's 30 years of experience and extensive field feedback went into the design of the valve. Our products have proven to be more durable and easier to use on the job. Each valve's model is based on a different set of standards. The gate valve may be capable of meeting EN, AS, or UL standards. AWWA and EN standards can be met by double eccentric butterfly valve. Each product has its own set of compliance requirements.
Without a doubt, China has the most comprehensive and cost-effective supply chain. The castings are the most expensive part of the water valve such as water air release valve. Every year, the quality of casting in China improves, but at a reasonable cost. There is always a way to assess the quality and price. AFC valve is your best bet for striking the right balance between quality and price.
