R74G/R
●
Excelon design allows in-line or modular installation
●
Full flow gauge ports
●
Balanced valve design minimizes effect of variation
in the inlet pressure on the outlet pressure
●
Standard relieving models allow reduction of
downstream pressure when the system is
dead-ended
●
Optional reverse flow models available for use
downstream of directional control valves
●
Modular installations with Excelon 72, 73, and 74
series can be made to suit particular applications

* Outlet pressure can be adjusted to pressures in excess of, and less than, those specified. Do not use these units to control
pressures outside of the specified ranges.
** Units with 250 psig (17 bar) outlet pressure range are available only with the T-bar adjustment; therefore substitute T at the 7th
position and S at the 9th position.
