Four Point Ball Valve Nipple

Product Overview

The SL-18 four point ball valve nipple is a white clip-on poultry nipple drinker that uses a ball-valve sealing principle instead of a simple spring pin. The white two-wing clamp grips the drinking pipe, the transparent middle body shows the internal ball, and the red lower section ends in a stainless steel actuation pin. A small green marker on the body helps staff identify this model during line maintenance.

The nipple stands 6.7 cm tall and weighs about 14.2 g, noticeably heavier than light spring nipples because of the complete ball-valve cartridge inside. When a bird nudges the pin, the ball lifts off its seat and water flows; releasing the pin lets the ball drop back and shut the line off tightly. The design targets farms that prioritize low drip rates and long service on automatic drinking lines.

Key Features and Benefits

• Ball-Valve Sealing - the internal ball seats firmly after each drink, giving a tight shut-off that reduces drips compared with basic pin nipples.
• White Two-Wing Clip - the white clamp snaps onto standard pipe ports and contrasts with red bases and colored pipework for easy spotting.
• Green Identification Dot - the green marker lets maintenance teams quickly distinguish this ball-valve model from other nipple types on mixed lines.
• Stainless Steel Pin - the metal trigger resists beak wear and corrosion, keeping actuation smooth across long production cycles.
• Transparent Middle Body - the see-through section lets inspectors confirm the ball is seated and water is flowing without removing the nipple.
• 14.2 g Sturdy Build - the heavier body indicates a complete valve cartridge inside, built for sustained commercial use.

Materials and Quality

The clamp and middle body are molded from white engineering plastic, with the transparent section allowing visual inspection of the internal ball. The ball, seal and stainless pin are assembled into a sealed cartridge that is pressure-checked for shut-off. Each nipple is visually sorted for correct color and marker position before packing.

The transparent middle section uses clear engineering plastic that resists yellowing under normal house light, and the white clamp stays flexible for repeated fitting. The ball cartridge is sealed inside so it cannot be tampered with on the line.

The transparent middle section uses clear engineering plastic that resists yellowing under normal house light, so inspectors can keep watching the ball seat for years. The white clamp stays flexible for repeated fitting, and the green marker dot is molded into the body rather than painted on, so it never wears off. The ball cartridge is sealed inside the housing, which prevents tampering on the line and keeps sediment away from the seat. Every nipple is tested for shut-off before packing, and samples are checked for color consistency across the batch. Farms value the tight closure of the seated ball, which helps keep litter drier than basic spring pins on the same line pressure.

How to Use and Maintain

Press the white wings onto the pipe port until the nipple seats squarely, then flush the line to clear debris. Check the green-marked nipples during routine walks and press the pin to confirm smooth movement. If a nipple drips constantly, replace the whole cartridge rather than trying to open it, and keep spare nipples on site for fast swap-out.

Because the ball valve closes more tightly than a simple spring pin, make sure line pressure stays within the range recommended for nipple systems; excessive pressure can push the ball off its seat.

Check the green-marked nipples during weekly walks and compare them visually with neighboring points. If a green-marked nipple drips, replace the whole unit rather than trying to open the sealed cartridge.

Applications

This ball-valve nipple suits commercial broiler and layer houses that run automatic drinking lines and want a tighter shut-off to protect litter. It is also a good choice for breeder sheds where water waste directly affects litter and floor quality.

Integrators and equipment distributors stock it as a premium nipple option, and it can be ordered alongside hanging cups, tees and float valves. Its green marker makes it convenient on mixed lines where several nipple types coexist.

Frequently Asked Questions

Q1: How is a ball valve nipple different from a spring nipple?

A ball valve nipple seals with an internal ball dropping onto a seat, which usually gives a tighter shut-off and lower drip rate than a basic spring pin.

Q2: What does the green dot mean?

The green marker identifies this four-point ball-valve model for quick recognition during line maintenance.

Q3: Can I see the valve working?

Yes, the transparent middle body lets inspectors watch the internal ball move when the pin is nudged.

Q4: Is this nipple compatible with existing push-fit lines?

The two-wing clip fits standard poultry pipe; share your pipe diameter if you need us to confirm before ordering. Send your pipe diameter with the inquiry if you need written confirmation before placing the order.
