Flow rate control valves

WebThese valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. They create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. Also known as 4-way and 5/3 closed center valves. Webmake sure the values used match the trim and valve selected. The Physics of Choked Flow In an ideal world, there is a linear relationship between the differential pressure ( P) and flow Rate (Q) as depicted by the “ideal” linear line in the graph below. In this case, as the P increases (as a function of decreasing P2), so does the flow rate ...
