Automatic Valve Opener (actuator) to Automate your Flow Bench Testing

Performance Trends’ valve opener will automatically set the valve lift and record data during your flow bench testing. It automatically finds the tip of the valve and zero’s itself out. It then steps through all valve lifts listed in your test in Performance Trends’ Port Flow Analyzer software. At each lift it waits a user specified stabilization time, then records the data and advances to the next lift point. 


When the test is complete, the opener closes the valve, and checks to see that no slippage has occurred, and turns off the bench if you have a SuperFlow ™ motor controller. Also if you have motor controller, like a SuperFlow ™ SF1020 bench, you can start the test and the Port Flow Analyzer software and valve controller can run the entire test. When done, the valve will be closed and the bench turned off. This is one tool that really will save you time and produce more consistent flow test results.

Custom Applications:

Our machine shop can do custom machining for brackets or adapters, or complete modifications for most all our mechanical components.  Here's some pic of how we adapted the Auto Valve Opener to a 4 Valve "flow block" (machined block with a prototype port).  Ask us for a quote for custom machining or adapters to most any of our products.
