Cutting Heads

The AccuValve may be used with either the DiaLine or A2 cutting head. The other options available
include the carbide and rubber splashguards, water nuts, alternative adapters, ruby and diamond orifices,
and many different nozzle sizes. Consult the Valve/Head option drawing for specific part numbers.
The key to effective operation is eliminating contamination above the orifice. Proper flushing and
rinsing will maximize orifice life. Areas upstream from the orifice should be flushed and washed with
water to eliminate any particles that can damage the orifices.
Caution: Verify that there is no water pressure in the valve before making any changes to the
valve or its components.

4.5 DiaLine Cutting Head

The DiaLine Cutting Head is normally used with diamond orifices for improved cutting performance
and superior life. Ruby orifices are also available. A new feature of the DiaLine cutting head is that the
diamond orifice and mixing chamber are replaceable. The Nozzle Nut provides an additional alignment
to the nozzle and helps in the removal of the nozzle if it is broken.

Installing the DiaLine Head

Always use AccuGoop on metal-to-metal mating surfaces
NOTE:
such as threads and the orifice retainer-adapter contact
area.
1. Make sure that the top of the head and bottom of the
adapter are clean, washed out if necessary.
2. Apply a light coat of HP lubricant such as AccuGoop
to the bottom face and threads of the adapter.
3. Install the Orifice Retainer flat side down into the
cutting head body. The top of the retainer has a slight
conical shape and holds the jewel orifice. This side
should still be visible after installing the orifice
retainer.
NOTE : Installing the Orifice the wrong way will
damage the orifice.
4. Thread the DiaLine head onto the bottom of the
adapter and torque to seal.
5. Use 3/8" OD x 1/4" ID hose or tube for feeding
abrasive into the head. Push the hose into the
connector until it bottoms. The hose may feel tight
and it may be necessary to put a light lubricant on the
OD at its end.
6. Loosen the nozzle nut and slide the nozzle up until it
bottoms-out in the abrasive body then re-tighten the
nozzle nut.
