Bk 109-814 Stock Tank Float Valve 3/4 in Thread Outlet

Product Description

The BK 109-814 is a bronze stock tank float valve designed to automatically regulate water levels in livestock watering tanks and similar agricultural or industrial reservoir applications. Built with a male inlet and male outlet configuration, the valve features a dual inlet thread that accommodates both connecting pipe and a locknut for a secure, leak-resistant installation. High-tensile serrated arms provide reliable float rod retention, and the machined flange seats firmly against the tank wall for stable mounting. Replaceable seals extend service life and reduce the cost of ongoing maintenance. A locknut is included in the package.

This float valve is suited for stock tanks, agricultural water troughs, and similar open-reservoir applications where automatic fill control is required. The 3/4-inch thread outlet fits standard pipe connections common in farm water systems and rural plumbing setups. The valve accepts float rod connections in the 14-inch to 20-inch range, allowing adjustment to match varying tank depths and water level requirements. Licensed plumbers and irrigation technicians are the typical installers, though experienced maintenance personnel familiar with tank plumbing frequently perform this work as well.

Installation Notes

Shut off the water supply and drain the tank to a safe level before removing an existing valve or installing this unit. Use thread sealant tape on all male threaded connections and tighten fittings to hand-tight plus a firm quarter-turn with a wrench — avoid over-tightening bronze fittings. Verify float rod length falls within the 14-inch to 20-inch connection range and adjust the arm angle to achieve the desired water level setpoint. Follow applicable local plumbing codes for agricultural water system installations.
