DWS & DW-PRV Series Valves

DWS SERIES Dirty Water Irrigation Valves

DW-PRV SERIES Dirty Water Pressure Reducing

For maximum performance at an economical price, no other remote-control irrigation valve can compare to the self-cleaning Griswold DW Series valve. The DW Series valve is the sensible choice regardless of your water source.

Even potable water will eventually clog the screens found in other “contamination proof” valves, leading to increased maintenance and long-term cost. The unique Griswold design allows the bronze-body DW Series valve to operate dependably under the most adverse conditions.

Sludge, algae, silt, and other contaminants have no effect on valve action. There are no filters or screens to clean and no vulnerable exterior tubing to be damaged. The entire diaphragm-control mechanism is contained within the valve itself.

Each time the valve opens or closes, the pilot orifice is wiped clean. A tapered metering pin controls opening and closing speed, eliminating water hammer or chattering.

Ideal for use with reclaimed or “Dirty” water.
