(3) C & W's Anti-Overfill System, combined with our Pressure Sensor and Broken Media Filter Sensor, give the highest level of protection available to your silos and dust collectors. Using advanced automated technologies can not only eliminate the human errors that occasionally occur, but can save time and money. The key component to having a protection system is the use of pinch valves that are activated to close when a problem is detected. This shuts off the flow of materials to avoid damage and accidents from occurring, while not interfering with the flow of normal operations. Without pinch valves (warning systems) are available.
(12) The VM type pinch valve has been designed to be used in a wide range of applications. Primary use is to arrest the product flow in pneumatic conveying lines, such as powders, granules, fibers and liquids. The wide range of sleeve materials in combination with various types of bodies enable the valve to be utilized in a number of industries.
The VM pinch valve consists of a metal outer body and an inner elastomer sleeve, reinforced by a fabric inlay, fixed between two flanges. The valve is "closed" by applying a control agent, i.e. compressed air or water under pressure, to the sleeve. The required pressure interval to close the sleeve is approx. 1.5 to 2 bar. Different types of flanges are available on request :
