Flexible Hose with Valves are Reliable
The rubber hose or flexible internal sleeve of a pinch valve is designed for having full control over the flow of media, and is made using wear-resistant rubber or other materials depending on the application. A flexible hose with valves is the ideal solution for various kinds of industrial areas, and come in different sizes to suit specific pinch valves.
The flexible hose with valves serves the purpose of tightly sealing the medium of operation in a closed position when the external pressure is applied onto it. This type of hose inside the valve is simply pushed inside the valve body and is fixed into place with the help of two end connections from the outside. The design of a pinch valve includes these end connections such as flanges, internally threaded sockets, tri-clamps, or weld-on ends. It is only the body, two end connections and the flexible hose with valves that make up a complete pinch valve. This is a huge benefit compared to other valve types because the flexible hose or sleeve is only one wearable part.

Flexible Hose with Valves Installation
When media flows through the valve, pressure is applied into a nipple fitting on the side of the body, and the valve changes its position. Usually, the valve is normally open so that when air pressure is applied, the flexible hose with valves closes. On the other hand, a pinch valve can be kept normally closed, so alternatively will need air pressure to open the rubber hose. The middle pinch section allows the media to pass through, and when it is required to close the flow path, the hose is squeezed shut through the pinch mechanism.
The installation of a flexible hose with valves is very simple to carry out, and the operator can either watch example videos of the re-sleeving process, or follow some written fitting instructions for pinch valves. The fitting process does not require the use of any specialized tools.
