Pinch Valve - How They Work. A pinch valve is a 2/2-way valve designed to shut-off or control the flow of corrosive, abrasive or granular media. It utilizes pressurized air to open or close the valve. In the open position, the valve has no restrictions and allows a wide range of media to pass through the bore.
Gold concentrators are aimed for the treasure hunter and gold prospector. At first, they may look somewhat imposing with their appearance, but these tools will change the way you approach prospecting for gold. What are Gold Concentrators? This tool is an item that uses centrifugal force in order to help with the recovery of gold.

Masterflex® Solenoid-Operated Pinch Valves. Choose from two-way NC, two-way NO, or three-way pinch valves. These are ideal where contamination is an issue, as the fluid only comes in contact with the tubing, not the valve. Tubing replacement is quick and easy, making these suitable for pharmaceutical or sanitary applications.
For optimum performance, Invacare recommends that each concentrator be on and running for a minimum of 30 minutes at a time . Shorter periods of operation may reduce maximum product life. If the concentrator has a damaged cord or plug, if it is not working pr operly, if it has been
