NOZZLE SHUT-OFF VALVE<br />
NSOV<br />
The Nozzle Shut-Off Valve (NSOV) is designed for use with<br />
dump style foot guns. The Nozzle Shut Off Valve completely<br />
stops all water flow to the cleaning nozzle in a waterblast<br />
operation while the foot valve is in its dump mode.<br />
• Allows the operator to freely move the nozzle without<br />
impairment of vision caused by sprayback (shown below)<br />
• Opens fully for unimpeded flow to the nozzle when blasting<br />
• Mounts between lance and foot gun (shown at right)<br />
• All pressure-bearing components precision machined from<br />
stainless steel<br />
