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.

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.

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.
