When the valve is closed, the disc sits upon the valve seat with both parts being machined in order to obtain a tight seal; the sealing surface can be flat or mitred. When the valve is opened, the flowing medium flows between the disc and seat....
For instance, trombones have a rotary valve which directs the airflow into lengths of tubing when they're rotated 90 degrees. Another type of valve found on trombones is the Axial flow valve, which has begun replacing the previously-mentioned rotary valve. There's also a valve called the...
A pneumatic globe valve is a crucial component in fluid control systems, known for its versatility and reliability. This valve operates by raising or lowering a plug or disc to regulate the flow of fluids through a passageway. Its design allows for precise control over flow rates, making it ...
I have an irrigation sprinkler that uses a flow check valve in the system. It lets the water flow out in one direction to irrigate my lawn, but will not water drain back in the opposite direction. The benefit of this is that it keeps the contaminated water on the lawn from draining bac...
