ZW204 Non-Modulating Float Valve

The ZW204 Non-Modulating Float Valve is used in storage tanks and fire protection systems to automatically control fluid levels by fully opening at low water levels and tightly closing at high water levels to prevent overflow.

The ZW204 Non-Modulating Float Valve is an automatic control valve designed to regulate fluid levels in storage tanks by operating in a fully open or fully closed position based on preset high and low water levels. It opens completely at a low set point to allow rapid filling and closes tightly at a high set point to prevent overfilling. Engineered for reliability and ease of service, the ZW204 incorporates standard maintenance-friendly components and supports high flow capacity, making it suitable for applications requiring consistent level control and dependable pressure regulation, including fire protection systems.

Features and benefits:

• Non-modulating float operation – Fully opens at low level and closes tightly at high level for precise tank level control
• High-flow pressure regulation – Maintains steady downstream pressure while supporting high flow rates
• Corrosion-resistant components – Stainless steel float and rod with Monel pilot valve seat for extended service life
• Integrated wye strainer and isolation valves – Simplifies system start-up, inspection, and maintenance
• Multiple valve body configurations – Available in globe, reduced port globe, and angle body designs
• Versatile end connections – 150 class flanged, 300 class flanged, grooved, and threaded options for installation flexibility
• Adjustable float rod lengths – 1’, 2’, or 3’ extensions available to accommodate varying tank depths
• Accessible pilot control options – Remotely mounted pilot standard with optional valve-mounted float pilot (VM)
