A mechanical device called an auto air relief valve is used to vent air from machinery, pipes, tanks, filters, or other areas. Its goal is to prevent air buildup inside the system, which could lead to pipe collapse. When the pressure inside the system rises above a predetermined level, the valve is programmed to automatically open and close.
The majority of valves are installed during the initial installation and stay there for the duration of the system. However, occasionally they may crack or leak, necessitating replacement. A drip of water from the air vent and rust and limescale stains are indicators of a leaking valve.
The air release valve closes by opening the air exit when the pressure reaches a particular point. A plastic ball, which is commonly used as the valve and is lighter than water, permits the release of air under pressure. The ball can endure temperatures of up to 90 degrees Fahrenheit and is climate resistant. The default Ra (relative air pressure) range for the Pressure Relief Valve is 16 to 32 uin. Make sure to select the appropriate pressure relief valve for your vehicle as it is crucial to its safety.
Although they can be utilized in a wet system as well, auto air release valves are often placed on dry riser systems. Through a vent hole, air is released from a piping to operate. The ball will travel higher and seal the vent hole once the water enters the ball chamber.
Every valve produced by the AFC Valve facility is certified to have undergone hydrostatic testing. The pressure test rating for the seat and shell is 1.5 *, and the pressure control valve rating is 1.1 *. We are positive that with the testing valve, all valves in water systems can be maintained correctly. For us, EN12266 was the ideal standard. Products that meet UL and FM standards will be produced in accordance with the UL/FM process.
The standard manufacturing process regulates each step of the production process. Every stage of manufacturing, including casting, machining, coatings, assembly, testing, packaging, and packing, is under the scrutiny of AFC's quality management system. Poor process control leads to low quality products.
The valve was created using extensive user feedback and 30 years of field experience. Our device has shown to be both more user-friendly and far more durable than other valves. All valve designs are based on different standards. The gate valve is built in accordance with UL, AS, and EN standards. Double eccentric butterfly valves are available that meet AWWA or EN requirements. Each product has its own set of requirements that must be met.
The most broad and economical supply chain is found in China. The most expensive component of the water gate valve is the casting. China is a top-notch supplier of casting, yet it's still inexpensive. There is always a way to evaluate the value and cost. The best valves are AFC valves and it is effective to balance quality and price.
