Watts 0780012 Valve

When you are managing high-flow water systems in commercial or industrial settings, the Watts 0780012 (Series 1250) is the industry standard for reliable liquid level control. This 1.25-inch heavy duty float valve is engineered to withstand demanding environments, featuring a rugged bronze body construction that resists corrosion in refrigeration and air conditioning applications. A key technical advantage is the machined flange on the inlet side, which provides superior support against tank walls, paired with a 1-1/4" female NPT pipe threaded connection for a secure fit. The assembly utilizes high tensile manganese bronze arms with a unique no-jam single lever action, ensuring consistent operation even under high-capacity flow conditions, rated up to 348 GPM at 100 PSI. Designed as a direct drop-in for the legacy 1250 model, this valve is the preferred choice for HVAC water level control where precision and high-pressure performance (up to 165 PSI) are non-negotiable.

• Enhanced Durability: The heavy-duty bronze construction ensures long-term service in cooling towers and irrigation systems.
• Precision Adjustment: Integrated serrated arms allow for quick, tool-free water level calibration to meet specific site requirements.
• Maximum Flow Capacity: Large-orifice design supports flow rates from 250 GPM at 50 PSI up to 348 GPM at 100 PSI.
• Simplified Service: Features replaceable seals and a no-bind lever mechanism to minimize downtime during routine maintenance.
• Secure Mounting: Specifically designed for tank wall-mounted installations with a machined flange for added structural integrity.

What is the maximum pressure rating for the Watts 1250 series?
This valve is rated for a maximum pressure of 165 PSI (11.4 bar), making it suitable for high-pressure industrial water lines.

Can the water level be adjusted after the valve is installed?
Yes, the Watts 0780012 features serrated manganese bronze arms that allow for easy vertical adjustment to set the precise shut-off point.

Is this valve compatible with potable water systems?
The Series 1250 is primarily designed for non-potable applications, including industrial water flow control, HVAC refrigeration, and agricultural irrigation.
