Watts 0770182 Valve

The Watts 0770182 Valve, technically identified as the ST1000 Standard Duty Float Valve, is a 1-inch NPT bronze body float valve designed for reliable fluid level control in commercial and industrial applications. This heavy-duty float valve is engineered for open tank or pressurized vessel installations, featuring a high-capacity flow rate to maintain set water levels efficiently. The ST1000 float valve utilizes a robust corrosion-resistant material construction, specifically cast bronze, to withstand harsh service conditions. It is compatible with standard copper or plastic floats via its threaded rod connection, making it a drop-in replacement for standard 1" float assemblies. Technicians often specify this model for cooling tower water level control and large-scale reservoir float valve systems due to its mechanical simplicity and durable pivot mechanism.

• Bronze Body Construction: Ensures long-term durability and resistance to dezincification in continuous-duty hydraulic applications.
• 1-Inch NPT Connection: Provides a secure, leak-free threaded interface for standard piping configurations.
• Adjustable Service: Lever arm design allows for precise calibration of the shut-off point based on the specific buoyancy of the attached float.
• High Flow Capacity: Minimized internal turbulence allows for rapid tank refilling without significant pressure drops.
• Universal Compatibility: Fully interchangeable with the ST1000 series for streamlined stock management and field repair.

Common Technical Questions

What is the maximum pressure rating for the Watts 0770182?
The ST1000 series is typically rated for supply pressures up to 100 PSI, though performance depends on the float size and arm length used to generate sufficient closing force.

Can this valve be used in potable water systems?
Yes, the bronze construction is suitable for various water applications, including storage tanks; however, always verify local plumbing codes regarding lead-free requirements for specific drinking water installations.

What size float ball is required for the 1-inch ST1000?
For optimal shut-off performance at higher pressures, a 7-inch or 8-inch diameter float is recommended to provide the necessary leverage for the 1-inch orifice.
