Pressure Regulators Residential and Commercial Drip Model 600XL and 90 Designed for installation on water lines to reduce high inlet pressure to a lower outlet pressure. The integral strainer makes this device most suitable for residential and commercial water systems requiring frequent cleaning because of sediment and debris. The direct acting integral bypass design prevents buildup of excessive system pressure caused by thermal expansion. The balanced piston design enables the regulator to react in a smooth and responsive manner to changes in system flow demand, while at the same time, providing protection from inlet pressure changes.

Pressure Regulators Commercial Model 500XL and 500XLYSBR Ideal for use where lead-free valves are required. Designed for installation on potable water lines to reduce high inlet pressure to a lower outlet pressure. The high flow capacity makes this device most suitable for industrial water lines and commercial irrigation systems. The direct acting integral bypass design prevents buildup of excessive system pressure caused by thermal expansion. The balanced piston design enables the regulator to react in a smooth and responsive manner to changes in system flow demand, while at the same time, providing protection from inlet pressure changes. Model 500XL Sizes: 1/2", 3/4", 1", 1-1/4", 1-1/2", 2", 2-1/2", 3" Sizes: 2", 2-1/2" and 3" available either FNPT or flanged Pressure rated at 300 psi Spring range 25 to 75 psi, factory set at 50 psi Lead-free bronze body and bell housing provides durability and long life FNPT Union end connection standard up to 2" May be installed in any position All internal parts corrosion-resistant Serviceable in-line Available tapped and plugged for pressure gauge (optional) Model 500XL 500XL Options (some options may be combined) 500XLC Female copper sweat 500XLHR Spring range is 75 to 125 psi, factory set at 85 psi 500XLHLR Spring range is 10 to 125 psi, factory set at 50 psi 500XLLPC Spring range is 10 to 35 psi, factory set at 20 psi 500XLSC Sealed cage bell and stainless steel adjusting screw for below-grade applications 510XL Same as 500XLHR except rated for 400 psi and spring range is 75 to 125 psi, factory set at 85 psi Model 500XLYSBR Sizes: 1/2", 3/4", 1", 1-1/4", 1-1/2", 2", 2-1/2", 3" Same features as the Model 500XL, plus: Includes lead-free wye strainer and close nipple Recommended for commercial installation where debris is prevalent in the water system Model 500XLYSBR 12

Automatic Control Valves Model ZW209 and ZW204 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. The 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. The Zurn Wilkins ZW206 lead-free 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. ZW200 Series Threaded end sizes: 1-1/4" thru 3" (300 psi max) Flanged ends sizes: 1-1/2" thru 10" Temperature Rating: Water 33 F to 180 F Pilot Spring Range: 15 to 150 psi Low pressure loss with superior performance over direct acting valves Ductile iron body 150 class, 250 psi max Internal and external FDA approved epoxy coating Isolation valves and wye strainers come standard Lead-free law compliant Opening speed control (sizes 1-1/4" thru 3") Model ZW209 Pressure Reducing Valve Model ZW204 Float Valve Stainless steel float standard on all sizes Remote mounted float pilot assembly standard Valve mounted float pilot option available Model ZW204 Float Valve Model ZW206 Lead-free Solenoid Control Valve Low voltage and line voltage options Normally open and normally closed switch options Other valve variations are available.
