Owing to the recent ageing and decreasing birth rate, providing nursing care to the elderly has become very crucial. As a result, it is necessary to develop wearable systems to aid in nursing care. To realise such a system, we require not only wearable soft actuators, but also a compact and flexible control valve. The purpose of our study is to develop a flexible, lightweight and compact control valve which can be safely attached to the human body. In this study, we proposed and tested a new type of control valve that consists of a vibration motor and a check valve. By giving continuous vibration, the valve can be kept open. As a result, we find that the valve can control a larger flow rate relative to its weight and size. We also apply the control device to a wearable actuator in the form of a McKibben artificial muscle.

Sanitary Check Valves Astonishing Features
Sanitary check valves are mainly used to prevent the backflow of fluids. These valves only allow the flow in one direction. They are usually very small and simple. As the name suggests, they are designed to maintain a high level of hygiene while maintaining a continuous flow of the medium. These valves are mainly used for highly viscous liquids such as gels and ice cream. Sanitary check valves are also known as the non-return valves. Here is some information about sanitary check valves with union connections....
Preparing a Beachside City for Future Storm Events with Proco ProFlex™ Check Valves - Case Study
Project: Post Hurricane Sandy Storm Drainage Update Location: Long Branch, New Jersey Contractor: Precise Construction Proco Products Agent: Valve Tech Sales Distributor: Atlantic Waterworks Long Branch is an oceanfront city of about 30,000 people in northern New Jersey. Much of the city borders the Atlantic Ocean to the east or the Shrewsbury River to the north. In 2012, Long Branch was one of many coastal communities that experienced severe flooding during Hurricane Sandy. The hurricane caused nearly $69...
Fascinating Features of Sanitary Check Valves
Sanitary check valves are mainly used to prevent the backflow of fluids. These valves only allow the flow in one direction. As a matter of fact, they are one of the few valves that have been self-automated to open and close with no assistance. Unlike other types of valves, check valves continue to work even after the plant has lost air, electricity or manual control from the operation team. They are widely used in a number of processes in sanitary industries. Check valves are found everywhere. You might be having...
Facts about Evaluating Sanitary Check Valves
The sanitary check valve is possibly the only best valve which can be used in your plant that can be operated without receiving any external assistance or giving any indication of the setting or about the condition. The special quality made the valve unique in the valve industry. Thus anyone can instigate to realize that this kind of valve is one apart from the rest. To select and evaluate sanitary check valves, it is necessary to know the basic forces and conditions influence the valves. Some common aspects of...
Sanitary Check Valves Principles and Parameters
The sanitary check valve will open when the media flows forward and will close when the medium returns to flow. These are mainly automatic valves, whose main function is to prevent the backflow of the means, as well as to avoid the inversion of the pump and the drive motor and the release of the container means. It is also used for safety protection in auxiliary systems where the pressure can rise above the system pressure. These are some of their parameters: 1.
