ABS Floating Ball

Product Overview

The SL-78 ABS floating ball is an automatic water level control valve built around a red engineering-plastic bracket and arm with a white ellipsoid buoy. The valve body mounts on the side wall of a water tank or drinker reservoir, while the buoy rises and falls with the water level, opening the inlet when the level drops and closing it when the set level is reached. This keeps a steady water height without electricity or manual checking.

The complete unit stands 32 cm tall, with a 13 cm base width and a 9 cm arm projection, and is packed 300 pieces per bag. The red bracket gives a rigid mounting point, and the sealed white buoy provides reliable flotation across normal drinking-water conditions. It is commonly used on poultry drinking tanks, cooling systems and small reservoirs where simple, fail-safe level control is required.

Key Features and Benefits

• Automatic Level Control - the buoy opens and closes the inlet as water moves, keeping a consistent level without pumps or electronics.
• Rigid Red Bracket and Arm - the engineering-plastic mount holds the valve firmly on tank walls and resists bending under normal buoy force.
• Sealed White Buoy - the ellipsoid float is airtight, so it stays buoyant even after long immersion in drinking water.
• 32 cm Overall Height - the tall arm gives a wide adjustment range for tanks of different depths and wall thicknesses.
• Easy Wall Mounting - the threaded base fits standard tank ports, so installation needs only a wrench and a check for leaks.
• 300 Pieces Per Bag - bulk packing supports farms and integrators that equip many tanks in one project.

Materials and Quality

The bracket, arm and valve body are molded from ABS engineering plastic, chosen for stiffness and drinking-water contact. The white buoy is a sealed hollow shell that resists waterlogging, and the internal inlet seal closes tightly against the valve seat. Threads are formed directly in the plastic body for a clean wall connection.

Each float valve is checked for buoy sealing and inlet shut-off before packing, and batches are visually sorted for correct color and complete molding. The rigid arm is sampled for bend resistance, so the valve keeps its set level through long service periods.

The red bracket uses rigid ABS that holds its angle under buoy force, and the white buoy is a sealed air shell that never waterlogs. The internal seal closes against a smooth seat for reliable shut-off.

The red bracket uses rigid ABS that holds its angle under buoy force, and the white ellipsoid buoy is a sealed air shell that never waterlogs even after years of immersion. The internal seal closes against a smooth seat, so shut-off is repeatable across thousands of cycles. Each valve is checked for buoy sealing and inlet shut-off before packing, and batches are visually sorted for correct red and white shades. The threaded base is formed directly in the plastic body, giving a clean wall connection without separate inserts.

How to Use and Maintain

Mount the threaded valve body through the tank wall port, tighten by hand with a light final turn, and adjust the arm angle so the buoy floats at the desired water height. Open the water supply slowly and confirm the valve shuts off when the level reaches the set point.

Rinse the tank and valve at each cleaning cycle, and check that the buoy moves freely without touching the tank wall. If the valve keeps dripping, inspect the internal seat for debris and clean or replace the seal; keep spare valves on site for fast swap-out.

Set the arm angle so the buoy floats at your target level, then test the shut-off by letting the tank fill to that point before stocking birds.

Clean the buoy and seat at each tank wash, and check that no feed dust coats the seat, since a speck of debris can stop the seal from closing fully.

Applications

This float valve suits poultry water tanks, drinker reservoirs and small cooling systems that need automatic level control. It is a standard component on farms running nipple drinking lines fed by overhead tanks.

It also works on backyard poultry water supplies, breeding stations and small industrial water circuits where simple mechanical control is preferred. Distributors stock it as a high-volume spare, and it combines with nipples, cups and tees in complete drinking-line accessory orders.

Frequently Asked Questions

Q1: How does the float valve control water level?

The buoy rises with the level and closes the inlet; when water drops, the buoy falls and opens the inlet again automatically.

Q2: Which tank wall port does it fit?

The threaded base fits standard tank ports; share your wall thickness and thread size if you need confirmation.

Q3: How many valves are packed in one bag?

Each bag contains 300 float valves as printed on the product label.

Q4: What should I do if the valve keeps dripping?

Check the seat for debris, clean it, and replace the seal or the whole valve if dripping continues after cleaning.
