| Test Procedure | |||
| - | - | - | Use the following test steps in order to test the pressure control valve: |
| 1. Leakage Check A. Apply B. Maximum allowable flow from tank port is |
|||
| 2. Bypass Valve Test A. Vent "GP" port to atmosphere B. Apply Note: The cracking pressure for the valve should be 1. One 177-7130 Shim raises the pressure roughly 2. One 177-7131 Shim raises the pressure roughly |
|||
3. Regulator Valve Test A. Connect "GP" port to pressure port B. Apply C. Full flow should be seen at the tank port Note: The cracking pressure should be 1. One 177-7130 Shim raises the pressure roughly 2. One 177-7131 Shim raises the pressure roughly |
