Fig 7. Pressure Relief Valve for Setting a Maximum Load
valve is fully open, there will be no pressure build up in the system (the
pressure/load gauge (
31
) indicator will not rise and show a load) and
excess pressure being pumped will vent off at the relief valve. Now,
start to turn the relief valve set knob (
69
) clockwise, (one complete
rotation at a time) and continue pumping. Eventually, pressure will
begin to build up in the system and the gauge (
31
) indicator will rise to
show a tonnage load. Once the load limit for the setting of the pressure
relief valve knob (
69
) has been reached, excess pressure will once
again vent off at the relief valve. Continue to turn the relief valve set
knob (
69
) clockwise until the required pressure/load is reached.
If you overshoot the pressure and hence load limit you require from
over-adjustment clockwise of the knob (
69
) and continuous pumping of
the handle (
32
), simply release the pressure from the system by
opening the pressure release handle (
30
) and then closing the release
handle again. Turn the pressure relief valve knob (
69
) anticlockwise to
reduce the load limit and re-pump the press via the handle (
32
).
Repeat the process as necessary to achieve the maximum applied
load setting required.
