The Regulator continued
Note: Be certain toverify the direction of air flow through the regulator.The incoming air (from The 3 Way Valve) Enters the port marked with an arrow.

After Building and Testing the Pneumatic Circuit
Determine These Performance Characteristics
1. How many times will the pneumatic cylinder cycle at 50 psi when the reservoir is charged to 150 psi?
2. What is the theoretical force of the piston at 50 psi?
3. What is the actual force of the piston at 50 psi?
4. What is the speed of the piston in inches per second at 50 psi?
5. Does pressure affect speed and if so, can you measure and graph the relationship?
Which answers can be found mathematically?Which should be measured directly?
