The high-performance non slam type check valve is intended to block flow in one direction. Its main advantage is its capacity to avoid water hammer, a situation in which the momentum underlying an abrupt rise in pressure shifts in one direction. Additionally, non-slam check valves are less likely to wear out over time, which lowers operating expenses. These valves are capable of withstanding a variety of operating circumstances.
Carbon steel is commonly used to create non slam check valve. The non-slam method is designed to endure extreme heat and pressure. Although the body of the valve is composed of durable, strong metallic elements, the valve's seat is made of soft materials. Additionally, they are made to withstand impact and corrosive substances.
Uses for the non-slam type check valve include applications involving gas and oxygen. They use a spring-assist system to regulate the closing of the valve disc. These valves come in sizes ranging from DN25 to DN50. Both horizontal and vertical installations are possible for them. Additionally well recognized for reducing water hammer, these valves.
In the event of a power outage, the non-slam type check valve is frequently employed as a protective valve. Additionally, it features little head loss and silent operation. The bronze bushing and shorter stroker reduce water hammer. Additionally offered are high-pressure and low-temperature variants of the Non-slam check valve.
A check valve that does not rely on the fluid's forward motion to close itself is known as a non-slam check valve. Instead, when the forward motion slows down, a spring causes the valve to close. Water hammer, which can harm pipe systems and equipment, is reduced as a result.
For many situations, a non-slam check valve is a fantastic option. By avoiding backflow and the reverse flow of water, these valves can lessen the effects of water hammer. They can continue to work even if a facility briefly loses power thanks to its non-slam architecture. They can aid in preventing flooding and damage to control valves. The largest manufacturer of non-slam check valves in the world is KHD Valves Automation Pvt Ltd. They offer the greatest customer service in the industry and their valves are constructed of premium steel.
It is possible to specify non-slam check valves that adhere to ANSI and ASME requirements. They can also be customized to fit particular customer needs. Axial flow non slam check valve come in a variety of body designs. Many have flanges.
Non-slam check valves do not need external actuation, in contrast to swing check valves. They provide a prompt remedy for backflow. Their drawbacks, however, include the restricted installation options and propensity to remain in the open position. The media and pipe system requirements, among other things, play a role in selecting the best valve. The performance criteria, such as temperature and pressure instances, should also be taken into account.
The AFC Valve factory guarantees that every valve it produces has undergone a complete hydrostatic test. For the shell test, the pressure test is normally 1.5 * pressure rating, and for the seat test, it is 1.1 * pressure control valve rating. We can be sure that every valve in the water system will be maintained correctly thanks to the test valve. The standard that we evaluated was EN12266. The UL/FM test technique is applied to products that adhere to both UL and FM requirements.
The standard production method closely monitors each stage of the manufacturing process. Every phase, which includes castings as well as machining, coating, and casting, has been documented by AFC's quality systems. A subpar product may be the outcome of uncontrolled procedures.
This valve's design is the result of our team's 30-year accumulation of knowledge and extensive field feedback. Our product is more dependable and simpler to use at work. Every valve is designed using a different standard. The gate valve can be able to satisfy EN, AS, or UL requirements. It is possible for double eccentric butterfly valves to meet AWWA or EN standards. Each item must adhere to the requirements set forth by the manufacturer.
The most extensive and effective supply network is in China. The largest component of water valve costs is casting. China produces castings that are both high-quality and reasonably priced. China-made castings' quality and cost can be evaluated. The ideal option is the AFC valve for finding the balance between quality & price.
