The protection of a building can be greatly improved by selecting the right kind of gate valve. They can be set up in various ways, from straightforward bolt-on models to trickier welded-in systems. These valves are helpful in other applications in addition to helping to protect a building from fire.
AVK fire protection gate valves have been designed and manufactured with safety in mind. They are designed to close in case of overheating of the pipeline. These valves can be used in a variety of applications.
The main benefits of these valves include protection of building, human life and equipment. They also help in reducing the amount of insurance rates. These valves also help to prevent fire spread if a air valve for water line and fuel valve are damaged. These valves are a very recent development in industrial tools that help prevent fire.
There are many different companies that offer fire-safe valves. The fire safety valve may include a primary drop-tight seat, fusible links, and a spring pack. They may also include a trigger assembly. This assembly is designed to maintain tension on the spring pack and close the valve when the valve is opened.
Arita Fire Solutions is without a doubt the market leader in the hydrant hopper segment among the countless manufacturers of piping equipment in the world. Gate valves of all shapes and sizes are part of the company's product line. The GV0-3, the most popular model offered by the company, is offered in a range of materials and finishes to meet the needs of different types of customers. The company's product line is completed by a wide selection of fittings and valve accessories. The company's active dealer network, in addition to its product line, enables it to offer a more individualized level of service to its customers. Additionally, the business provides free technical support, product training, and a variety of warranty and replacement part options. A gate valve with gearbox yoke, which can be used for throttling, inlet, and outlet service, is only produced by Arita in the entire world.
UL fire protection gate valves are tested in accordance with the standards set by Underwriters Laboratories (UL). These valves are tested for durability, leakage, corrosion protection coating, water absorption, and close quarters durability. The tests are carried out at atmospheric pressure and at a pressure that is four times the working pressure. During the tests, the valves are not allowed to sustain permanent distortion or cracking.
The valves are also subject to a 50,000 cycle test. This test is carried out at an average pressure of 427degC for two hours. The valve body is also tested for hydrostatic strength. The valve must have a minimum hydrostatic strength of 11.8 ml/hour per centimeter of the nominal valve size. This strength must not exceed 12 bar.
The three most common types of fire hydrant gate valves are generally. A solid wedge gate valve is the first type. This kind is made to function with almost all fluids.
The second kind of gate valve is flexible. When thermal binding is a problem, the valve's performance is enhanced by its flexible design. Additionally, it adjusts to harmful piping stresses.
Knife gate valves are another option. These kinds were first created for the pulp and paper sector. Additionally, they are utilized in high pressure applications. The blades are made to cut through solids and are narrower than the closure element. Usually, socket weld ends are used on the blades.
Additionally, non-rising stem valves exist. The stem on these models threads into the disc. The stem makes it simple to quickly verify the position of the valve visually. When vertical space is at a premium, they are especially helpful.
AFC Valve guarantees that every valve manufactured in the factory is hydro-statically checked. The seat and shell pressure ratings are 1.5 * for the pressure test, and 1.1 * for the pressure rating. We are confident that each valve will function within the water system due to the testes. EN12266 was the standard we used. We adhere to the UL/FM process to ensure that our products meet UL and FM Standards.
The valves are controlled at every step of manufacturing through a standard manufacturing procedure. From castings to coating, machining, assembly, testing, and packing AFC's quality control system has been monitoring every step with IPQA to ensure that every step is well controlled and recorded. This results in a product that fails to control its process.
This valve design is the result of 30 years of experience from our team, as well as extensive feedback from field workers. Our product has proven to be more reliable and simpler to utilize in the field. The valve designs are all based upon different standards. For example, the gate can be designed to meet EN as well as AS standards. Double eccentric butterfly valves comply with the EN and AWWA standards. Each product must meet its own standards.
China has the most extensive and effective supply chain. The water valve's biggest expense is the castings. High-quality castings from China are improving yearly, but they are reasonably priced. There is always a way to evaluate price and quality. The AFC valve is the ideal option for striking the ideal balance between value and cost.
Depending on the type of fire protection water gate valve you are installing, you may have to perform some form of inspection. These may include an inspection to determine whether there is any leakage, a test to find out if the valve is working as it should, or an ITM. The frequency of inspection depends on how the valve is monitored.
Some manufacturers have developed a system that can alert you when the valve is closed. This method, known as electronic supervision, can reduce the frequency of inspection. Depending on the type of valve you are installing, you may need to install special equipment to control the valve.
Fire protection gate valves typically operate the same way as globe valves. They use a plate-like barrier to stop fluid flow. The only difference is that the gate requires more time to open and close.
