3″ POLISHED, GROOVED SPRAY HEAD AND VALVE
PRECISION CAST ALUMINIUM
Fully adjustable cast aluminium spray ring allows infinite flow and spray pattern variation. Air pressure holds the valve closed while water pressure opens the valve (approximate valve opening pressure 0.55 bar ⁄ 8 psi). An internal spring closes the valve when the water pump is shut down or an absence of air pressure exists and eliminates the need for additional shut off valves.
