Watts 0770179 Mechanical Float Valve 3/8 in Bronze

Product Description

The WATTS 0770179 is a mechanical float valve designed to automatically control liquid levels in tanks, reservoirs, and open vessels. Built with a bronze valve body, it handles working pressures up to 125 psi and maximum operating temperatures up to 180 degrees F. The 3/8 inch male pipe thread (MPT) inlet and outlet connections make installation straightforward in standard plumbing configurations. At 50 psi, the valve delivers a flow rate of 14.00 GPM. Licensed plumbers and water treatment technicians are the primary installers for this type of valve in commercial and light industrial applications.

This float valve is suited for potable water systems, industrial process tanks, cooling tower makeup lines, and irrigation holding tanks where reliable automatic level control is required. The all-bronze construction holds up well in wet environments and resists corrosion in water service. Its mechanical operation requires no electrical power, making it a dependable choice for remote or utility installations where simplicity and durability are priorities.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC and local plumbing code requirements. Shut off the water supply and relieve system pressure before removing an existing valve or making new connections. Apply appropriate thread sealant to all MPT connections and verify there are no leaks before returning the system to service. Size the float arm and ball assembly for the tank depth and desired liquid level prior to final installation.
