Aqualine BFLV-20128 Brass Float Valve Assembly

Product Description

The AQUALINE BFLV-20128 is a brass float valve assembly designed for automatic water level control in tanks, cisterns, and open reservoirs. The assembly includes a 2-inch brass valve body, a 3/8-inch diameter by 12-inch stainless or brass rod, and an 8-inch poly float that rises and falls with the water surface to open and close the valve. As water drops, the float descends and opens the valve to allow refill. When the set level is reached, the float rises and shuts off flow. Plumbers and pool service technicians install this type of assembly where reliable, mechanically simple level control is required without electronic sensors or external controllers.

This float valve assembly is suited for use in residential and light commercial applications including water storage tanks, livestock troughs, cooling tower makeup water, and pool or spa auxiliary tanks. The brass valve body provides corrosion resistance in potable and non-potable water systems. The poly float is lightweight and resistant to waterlogging, maintaining consistent buoyancy over extended service life. This assembly is a direct-fit replacement for standard 2-inch float valve installations where a rod-and-float style actuator is specified.

Key Features

• 2-inch brass valve body for durable, corrosion-resistant flow control
• 3/8-inch diameter by 12-inch actuating rod provides extended lever arm for responsive shut-off
• 8-inch poly float resists waterlogging and maintains consistent buoyancy
• Mechanically operated with no electrical components required
• Suitable for potable and non-potable water level control applications

Compatibility

Designed as an OEM-style replacement for standard 2-inch brass float valve assemblies used in tanks, reservoirs, and water level control applications requiring a rod-and-float actuator style.

Installation Notes

Installation is typically performed by a licensed plumber. Shut off the water supply and relieve system pressure before removing the existing valve. Ensure the float rod has adequate clearance inside the tank to travel freely through its full arc without contacting tank walls. Verify thread connections are sealed with appropriate thread tape or compound rated for the water service type.
