Hydraulic valves control the flow of fluid in a hydraulic machine; thereby, maintaining the required pressure in the system. These valves have spools that slide to different positions to control the flow of fluid. Based on application, directional valves, pressure valves, and flow valves are key types of hydraulic valves. Hydraulic control valves are designed to be stackable. Each output valve is used for a particular operation, while input valves supply fluid. Control valves have a high tolerance for pressure and the ability to prevent fluid leakage. Therefore, these valves are expensive than other parts of a hydraulic system.

The global hydraulic hose and fittings market is expected to grow at a steady pace during the forecast period. In 2016, the application of hydraulic hose and fittings in the construction equipment, among the end-users, accounted for the major share of the global market with 31.59% share. Construction machinery like cranes, mini excavators, construction excavators, backhoe loaders, wheel loaders, motor graders, and other general machinery contributed significantly to the growth of the market. The growing emphasis on infrastructure development is going to drive the global market for hydraulic hose and fittings. This will pertain to the demand of new construction equipment and replacement of the old equipment.

The manufacturing industry has witnessed radical changes in processes that are used to manufacture products. Earlier, goods were produced with bare hands. Subsequently, with advances in technology, machines were used to produce goods. This shift in production techniques is termed as the Industrial Revolution. The Industrial Revolution has its roots in England, where it began in the 18th century and spread beyond national boundaries to neighboring countries such as Germany and France. By the second half of the 18th century, the revolution spread to the US.

Since a long time, manufacturers and industrial users have faced the problem of grit, waste, and metal parts left behind after machining processes. The unwanted materials demanded cleaning and washing to keep the industrial floor space tidy, thus preventing them from harming personnel or assets, and ensuring the final product quality. Manual cleaning of such metal parts or components consumed a considerable amount of time and cost, and also resulted in the loss of productivity. With industries facing the issue of rising labor costs and productivity concerns, automated washing has emerged as a major necessity over the years.

With the increase in older population worldwide, the risk of visual impairment due to chronic eye diseases will increase globally. Vision can be classified into the following

The term "extremity" is generally used to refer to a person's limbs and related parts. Upper extremities include the shoulders, hands, elbows, forearms, wrists, and fingers. Lower extremities consist of the feet, toes, ankles, knees, shins, and thighs. The extremity products are used to treat, repair, replace, or heal extremity injuries such as fractures or damage. These products include external recovery braces, surgical implants, joint replacements, biologics, and external support implants.

Still images refer to static images and photographs that form a major part of the visual content available today. The global still images market deals with the supply and licensing of pre-produced images for various types of media, such as newspapers, magazines, websites, and blogs. Marketers employ visual content to communicate messages and themes effectively to customers. Still images allow organizations to enhance user engagement, increase brand awareness, and generate leads. The global still images market is likely to grow at a CAGR of 7.76% in terms of value and 5.4% in terms of volume during 2016-2021.

The global market for welding respiratory systems is expected to be driven by the increasing demand from key end-user industries such as manufacturing and construction. Stringent and comprehensive safety regulations also drive the growth of the market. However, the emergence of new and advanced welding techniques poses a challenge to the market as these techniques involve less manual input, which reduces the exposure time. Respiratory protection including welding respiratory protection is among the top-five violations cited by OSHA. Such high non-compliance is mainly due to wearer discomfort as well as negligence of worker safety. Another factor restricting market growth is the regular maintenance required for various components of respiratory protection equipment. Most employees fail to maintain the components of equipment including valves, tubes, cartridges, and facepiece, which is an integral factor for the efficient performance of equipment.

Snoring is the vibration of the respiratory channel in the human body that results in the generation of sound due to obstructed air movement during breathing in the sleep. In some of the cases, the sound may be soft, but in some cases, the sound could be loud and unpleasant. Snoring during sleep may be a first alarm of obstructive sleep apnea (OSA). The research study suggests that snoring is one of the factors of sleep deprivation.

The global industrial wireless sensors market is extremely dynamic, with the rapid technological advances strengthening its products and applications. The need for monitoring and analyzing real-time data is one of the major factors spurring the use of industrial wireless sensors. These industrial sensors are transducers that alter a physical quantity into electrical signals. The signal indications are processed through an electronic automation system and portray physical variations or error signals in the device or instrument. Based on this, industrial wireless sensors are classified into the following types: flow, temperature, pressure, gas sensors, and others.
