A device that allows excess air or vacuum to escape from a system is known as an air release and vacuum valve. This is significant for a number of reasons. Excess air in a system decreases capacity, increases power consumption, and can even cause line breakages. An air release and vacuum valve is commonly installed at high locations in a pipeline, near a pump, or at the end of long pipe lengths or deep well installations.
In water pipes and sewer force mains, air release valves are widespread. These valves are noticeable and situated at high places throughout the system. They may also be found slightly downstream of a flowing body of water. A water pipeline system would be incomplete without an air release valve. Its primary function is to release trapped air in the pipeline to ensure maximum efficiency. It also aids in the prevention of water hammer. An air release and vacuum valve is a vital part of a pipeline system.
An air release and vacuum valve helps to vent air pockets to the atmosphere. These air bubbles can collect at the highest points in a system and create a vacuum. An air release and vacuum valve will help to eliminate these air pockets and keep the system pressurized.
AFC Valve assures that every valve manufactured in our factory has undergone hydrostatic testing. Typically, the pressure to be evaluated for seat and shell tests is 1.5 *. We are confident that using the testes valve, all air valve for water line systems can be properly maintained. The standard that we used was EN12266. The UL/FM test procedure applies to products that meet both UL and FM standards.
The automatic air release valve is controlled throughout the manufacturing process using a consistent manufacturing procedure. AFC's quality systems documented every stage, including castings, machining, coating, and casting. Controlling processes can lead to a faulty product.
The air vacuum relief valve design is the result of 30 years of experience and extensive feedback from field employees. Our product is more dependable and simpler to use on the job. Every valve model is built to a different set of specifications. The gate valve, for example, can meet EN, AS, UL, and FMs standards. Butterfly valves with double eccentrics meet EN and AWWA requirements. Every product must meet its own manufacturer's standards.
China has the most extensive and cost-effective supply chain. The castings are the most expensive part of the air vent valve for water. Each year, the quality of castings in China improves, but at a reasonable cost. The quality and cost of castings in China can be evaluated. AFC valves are the most effective way to achieve a balance of quality and price.
