Automatic Control Valves
Other valve variations are available. Refer to Zurn Wilkins Automatic Control Valve Catalog ZMKTG480-01 or consult www.zurn.com.
Sizes: 1-1/4" - 16" Stainless steel float standard on all sizes Remote mounted float pilot assembly standard Valve mounted float pilot option available
Model ZW204
Model ZW204 Float ValveThe Zurn Wilkins ZW204 pilot operated non-modulating float valve is designed to maintain accurate fluid levels in tanks. When the fluid level reaches the low set-point of the float rod assembly, the main valve opens to fill the tank. Once the fluid level reaches the high setpoint of the float rod assembly, the main valve closes drip-tight.
Model ZW209TH
Model ZW206
Sizes: 1-1/4" - 16" Low voltage and line voltage options Normally open and normally closed switch options
The Zurn Wilkins ZW206 is designed to be either fully open or fully closed in response to an electrical signal to the solenoid pilot assembly. The function of this valve saves labor while allowing for remote on/off operation of many irrigation applications.
The Zurn Wilkins ZW209 pilot operated pressure reducing valve is designed for many applications where the reduction of high inlet pressures to a safe and stable outlet pressure is required. The pilot assembly reacts to changes in downstream pressure, allowing the main valve to modulate between the closed and open position ensuring a constant downstream set pressure.
