Pinch valves are designed to control the flow of liquids and gases. They are non-contact and simple in design. Learn more about their components and applications. After reading this article, you should have a better understanding of this type of valve. But first, let’s review their main features. This article will discuss the features of pinch valves and provide a brief introduction to their construction.
Non-contact
Non-contact pinch valves are designed to control fluid flow without touching the fluid. Available in two-way NC and two-way NO configurations, they are ideal for sanitary and pharmaceutical applications where contamination is a concern. These valves are easily replaceable with quick-change tubing. Some include mounting clips for added flexibility. Geeplus offers many types of non-contact pinch valves to meet specific needs.
Non-contact pinch valves feature a sleeve that is made of a material that resists abrasion. In some applications, polyurethane is used to improve abrasion resistance. Some valves also feature food-grade rubber sleeves. This additional layer of protection improves strength and resistance to wear.
Simple design
A simple design for pinch valves allows for quick installation and maintenance. The design is made up of a sleeve and body that close over the area in contact with the medium. The design is able to handle a variety of fluids and is ideal for food-grade applications.
The sleeve is made from rubber, while the body is usually made of steel bars. TheĀ more helpful hints rubber sleeve stretches and closes to reduce the flow of the media. The sleeve is the only part of the valve that comes into contact with the media, so it is important to select materials that will not degrade over time.
Components
The body of a pinch valve is made from a number of materials, including neoprene, silicone, and EPDM (ethylene propylene diene monomer). Pinch valves are often lined with EPDM, a synthetic rubber membrane with a higher heat resistance than natural rubber. Other options include FKM (fluoro-knitted nitrile). Other materials that can be used for the body of a pinch valve include stainless steel, aluminum, or plastics.
The sleeve surrounding the body is another component that provides a reliable seal. This sleeve also serves as a safety guard during operation, and is used to isolate the flow of a fluid when it’s needed.
Applications
Pinch valves are a type of valve that uses an internal rubber sleeve to close or throttle the flow of a medium. They are typically attached to the main system via flanges. When closed, the rubber sleeve catches any particles that are inside and provides a good closing effect.
Pinch valves are also used to control the flow of corrosive and abrasive fluids. They are a good choice for these applications because they do not require an actuator, and because their flow path is straight, they do not cause clogging or turbulence. They also use less energy than other types of valves, and they require little maintenance.
Cost
A pinch valve is a valve that controls a fluid flow using a sleeve of compressed air or fluid. They are typically used for applications where metal valves are not appropriate. These valves are available in a wide range of sizes and feature a variety of flanged connections. Depending on the size and elastomer used for the sleeve, they can operate with vacuum or moderate pressure.
The price of a pinch valve varies depending on the type of valve and its performance. Some pinch valves are designed for open/close applications, while others have a throttle function. When choosing a pinch valve, make sure the openings are the same size to prevent slack. If you’re looking for long-term performance, you’ll want to choose an internal valve with a high life-span.
