DIFFERENTIAL PRESSURE SIGNALING SYSTEM COMPLETE WITH ALUMINUM GAMMON GAUGE.
Peak-Hold Reading
The maximum differential pressure that is measured during an operation automatically locks the piston so that the operator will have that information without actually having watched the gauge at the time. After the reading has been seen, the operator releases the piston by turning a knob. It is usually impossible for the operator to see the gauge while refueling an aircraft so the highest differential pressure reading is rarely seen. This feature eliminates the problem just as in the case of an unmanned facility such as a pipeline or hydrant system. Patent applied for.
Push Button Test Valve
Hold the button in to relieve pressure under the piston. System pressure will force the piston down so the operator can observe motion. Erratic movement of the piston indicated contamination of piston and glass cylinder, requiring cleaning. Note: This test releases about 50ml of fuel which can be collected in a cup or directed to recovery systems.
Calibration Testing
To meet API-1581, you should have a 3-way valve. Our 3-way valve meets this requirement and is used to check calibration as well as to check free movement of the piston.
- Establish flow in the system. The gauge should indicate a pressure drop.
- Push the test button. The piston should travel to the bottom of the scale.
- Release the button and stop flow in the system. The piston should return to zero.
Pressure Relief Feature
Incorporated in all Push Button models is a thermal expansion relief valve set at 300 psi to protect the gauge from excessive pressure if isolation valves have been closed.
