Abstract
A valve manifold includes a valve body carrying pairs of laterally spaced piston actuated valves controlled by control modules operative to selectively pressurize and exhaust an outlet port connected to a fluid device and configured in groupings permitting varying valve functionalities.
Claims8
A method of detection a leak in a test part, the method comprising the steps of:
- mounting a test part in a test fixture;
- pressurizing a high pressure line to close a high pressure valve;
- pressurizing a low pressure line to close a low pressure valve;
- de-energizing an exhaust pilot valve to open an exhaust valve;
- de-energizing an isolation pilot valve to open an isolation valve;
- energizing one of a high pressure pilot valve and a low pressure pilot valve to open one of the high pressure valve and the low pressure valve, respectively;
- monitoring pressure transients to determine if the test part has a leak;
- and
- indicating if the test part has the leak.
