White Float Valve

Product Overview

The SL-79 white float is an automatic water level control valve built from a white engineering-plastic valve body, an adjustable arm and a ribbed ellipsoid buoy. The valve mounts through a threaded tank wall port, and the buoy rises and falls with the water level to open or close the inlet automatically. The ribbed buoy design gives added strength while keeping the float light and easy to position.

The complete unit stands about 33 cm tall, and the large ribbed buoy measures 8 cm across, weighing 58 g per piece. Packing holds 400 pieces per bag, which supports bulk orders for farms and integrators. The all-white body works on overhead tanks, drinker reservoirs and small farm water circuits where a simple mechanical level valve is preferred over electronic controls.

Key Features and Benefits

• Ribbed Ellipsoid Buoy - the 8 cm ribbed float stays strong and buoyant while resisting denting against tank walls.
• 33 cm Adjustable Arm - the long hinged arm reaches deeper tanks and lets users fine-tune the set water level.
• Threaded Wall Mount - the valve body screws into standard tank ports for a quick, leak-checked installation.
• All-White Plastic Build - the drinking-water-friendly material blends into most tank setups and resists normal farm additives.
• Automatic Mechanical Control - no power supply or electronics are needed; the buoy closes the inlet whenever the level reaches the set point.
• 400 Pieces Per Bag - high-quantity bagged packing suits large projects equipping many reservoirs at once.

Materials and Quality

The valve body, arm and ribbed buoy are molded from white engineering plastic suited to drinking-water contact. The ribbing on the buoy adds wall strength without extra weight, and the buoy shell is sealed airtight so it never waterlogs. The internal inlet seal closes against the seat as the float rises, and the hinge joint is reinforced for repeated cycles.

Each valve is tested for buoy sealing and inlet shut-off before packing, and finished pieces are visually sorted for color and molding completeness. Batches are sampled for arm flexibility, so the valve keeps responding reliably over long service periods.

The ribbed buoy resists dents against tank walls while staying light, and the all-white plastic is stable under normal farm water additives. The hinge joint is sampled for repeated cycles.

The ribbed buoy resists dents against tank walls while staying light enough to lift easily with the water level. The all-white plastic is stable under normal farm water additives, and the hinge joint is sampled for repeated open-close cycles before batch release. Each valve is tested for buoy sealing and inlet shut-off before packing, and finished pieces are visually sorted for correct color and molding completeness. Because the bag holds 400 valves, counts are verified at the pack house so large projects receive accurate stock. The long 33 cm arm also reaches deeper tanks, and the ribbed grooves are easy to wipe clean during routine tank washing, keeping the buoy free of dust and feed residue.

How to Use and Maintain

Screw the valve body into the tank wall port by hand with a light final turn, adjust the arm angle until the ribbed buoy floats at the desired level, then open the water supply slowly. Confirm the valve shuts off at the set point and does not drip at the seat.

Flush the tank and valve at each cleaning cycle, and check that the buoy hangs freely without touching walls. If the valve keeps dripping, clean the seat of debris and replace the seal or the whole valve; keep spares on site for fast swap-out.

Set the arm angle so the ribbed buoy floats at the target level, and test fill and shut-off once before putting the tank into service.

Wipe the ribbed buoy during tank cleaning, since grooves can trap dust. If the valve drips, clean the seat and check the buoy swings freely before replacing the unit.

Applications

This white float suits overhead poultry water tanks, drinker reservoirs and small farm water circuits that need dependable mechanical level control. The ribbed buoy also works in larger tanks where the float may be bumped by internal parts.

It is used on broiler, layer and breeder farms, and by distributors stocking replacement floats for local tanks. It combines with nipples, cups, tees and pipes in mixed export accessory orders for poultry projects.

Frequently Asked Questions

Q1: Why is the buoy ribbed?

The ribbing strengthens the ellipsoid float so it resists dents and stays buoyant even after long service in the tank.

Q2: How do I set the water level?

Adjust the hinged arm angle until the buoy floats at the height where you want the inlet to close.

Q3: How many valves are packed in one bag?

Each bag contains 400 float valves as printed on the product label.

Q4: What should I do if the tank overflows?

Check the seat for debris, confirm the buoy moves freely, and clean or replace the seal if dripping continues.
