High-pressure system
Intensifier
Low-pressure supply water goes into the intensifier, where it is pressurized for piercing and
cutting.
The hydraulic center section contains hydraulic fluid, which is used to compress water in the
high-pressure ends.
The pressurized water exits the high-pressure end through a check valve and goes to the
attenuator.
Attenuator
The piston stroking in the hydraulic center section of the intensifier causes a brief change of
water pressure. The attenuator compensates for high-pressure water fluctuations and maintains
a consistent output pressure.
The 2-liter attenuator has a guard installed. The attenuator guard is intended to keep personnel
safe from studs or end caps, which can become projectiles if the attenuator fails.
Bleed-down valve
The bleed-down valve is a normally open, air-actuated dump valve. The valve releases
high-pressure water from the system when the pump is turned off or when the operator changes
from cut mode to pierce mode.
