  • Introduction and Type of Check Valve Animation

    The check valve animation is an automatic valve. It flows forward and closes in reverse flow. The valve is opened by the fluid pressure of the system and any flow reversal closes the valve. The exact operation will vary depending on the type of check valve mechanism. The most common types of check valves are swing, lift (piston and ball), butterfly, stop and swashplate.   Type of check valve ...

  • 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. ...

  • Learining how to Choose Materials for Gas Valves

    The materials and the quality of gas valves are so important that their disqualification will lead to leakage in-or-outside the body of the valve. If the strength, rigidity and overall performance of the components of the valve body cannot meet the requirements or even break, it will result in the spillage of gas and explosion. Therefore, material and quality are the most critical part during the ...

  • Development of small-sized flexible pneumatic valve using vibration motor and its application for wearable actuator

    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 ...

  • Porirua New Zealand – WaStop® DN225 - Case Study

    Porirua City located 20 km north of Wellington has over 70 storm water outlets into the harbour. A number of these outlets are very flat on their approach to the harbour which generally means they are severely influenced by high tides. The problem with these outlets is that if a rain fall event coincides with a high tide, the ability of the storm water network to discharge is severely restricted. ...
