SV4105 80mm Spray Valve Aluminium

SV4105 80mm Spray Valve Aluminium

The SV4105 is cast from Marine grade alloy with an output capacity of up to 1000 litres per minute (265 US Gallons per minute) and provides a dense even spray discharge of up to 6.7 metres (22 feet) and a spray width of up to 11 metres (36 feet). Air pressure holds the valve closed while water pressure opens the valve (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. Fitted with an adjustable spray band this allows adjustment of spray pattern and output volume.

The SV4105 has a stainless steel equivalent the SV4104.
