Description

OPERATING CHARACTERISTICS

The Relayair® Valve has three basic uses:

1. As a nongraduated relay to provide a large flow of air from a separate source when piloted by small amount of control media and to stop this flow and exhaust the air to atmosphere when the control pressure is vented.

2. As an interlock to govern the flow in one circuit by placing its control in another independent circuit.

3. As a pressure-sensitive sequence valve for such circuit functions as timing, cycling, etc.

APPLICATION NOTES:

RELAYAIR Valves operated by pilot pressures less than 35 psi utilize one control spring while valves operated by pilot pressures greater than 35 psi use two springs. To obtain pilot pressures less than 10 psi, two diaphragms are used in series.
