Watts 0770181 Float Valve

The Watts 0770181 (Series ST750) is a 3/4 inch mechanical float valve engineered for precision water level control in high-demand commercial and industrial systems. Built with a rugged bronze body, this standard-duty valve features 3/4" male NPT threaded connections, making it a reliable drop-in for HVAC refrigeration cooling towers, evaporation condensers, and large-scale irrigation systems. With a maximum pressure rating of 125 psi and a temperature threshold of 180°F, it handles harsh operating environments where plastic alternatives fail. The assembly includes a cotter pin pivot arm and a fully replaceable plunger and seals, allowing technicians to perform field service without pulling the entire valve body from the line. The serrated adjustment arm provides exact calibration of the water line, preventing short-cycling of makeup pumps. Whether you are managing industrial water tanks or specialized agricultural float valve applications, the ST750 delivers a consistent 19 GPM flow rate (at 55 PSI) to maintain optimal system stasis.

Key Benefits for Technicians
  • Bronze Construction: High-tensile bronze body prevents corrosion in cooling tower float valve applications and ensures structural integrity under 125 psi.
  • Serviceable Design: Features replaceable seals and plungers, significantly reducing downtime during routine maintenance cycles.
  • Serrated Arm Adjustment: The serrated pivot arm allows for locked-in, precise water level settings that won't slip due to vibration or high flow turbulence.
  • Universal Compatibility: Standard 3/4 inch male NPT threads ensure seamless integration into existing commercial plumbing systems and tank walls.
Common Questions & Troubleshooting
  • What is the maximum operating temperature? The ST750 is rated for fluid temperatures up to 180°F, making it suitable for both cold and hot water makeup applications.
  • Can I replace the internal components? Yes, the plunger assembly and seals are fully replaceable. We recommend stocking Watts ST750 repair kits to address mineral scaling or wear without replacing the valve body.
  • Is this suitable for high-pressure irrigation? It is rated for 125 psi. If your system exceeds 55 psi inlet pressure, ensure your float ball and rod are sized correctly to counteract the additional buoyant force required for a positive shut-off.
