Watts BA2 Float Valve, Polyphenylene Sulfide

The Watts BA2 is a 2" pilot-diaphragm tank and reservoir fill valve that runs at full flow until it shuts off, cutting pump wear on large pump-fed tanks. It features a polyphenylene sulfide body and a buna-n seat. Rated to up to 140°F.

This 2 inch tank valve is made from polyphenylene sulfide and has a very large flow rate. It utilizes a differential dual weight system that reduces pump wear and saves electricity. This valve is diaphragm activated and has a steel pin that runs inside the pilot center which acts as a self cleaning mechanism which is unique to Apex valves.

Features

• Designed for use in large pump-fed water tanks or reservoirs that maintain full-flow, extremely high-volume levels of water
• Features a differential dual-weight system that reduces pump wear and saves electricity
• Automatically enables a large flow rate until it turns off, ensuring safe, smooth and cost-effective fluid control
• Built for durability and long life using fiberglass-reinforced nylon, Acetyl (POM) and corrosion-resistant polyphenylene sulfide
• Applications include irrigation, rainwater harvesting, agriculture, horticulture, livestock watering, farm and ranch and/or hydroponic systems

Common Questions

Does this include the float ball and rod?

Yes. This valve has an integral float and installs complete; there is no separate float ball or 3/8"-16 rod to buy, unlike the Watts bronze lever-arm float valves.

Can I use it on drinking water?

No. This valve is not certified lead-free and is for non-potable service only — cooling tower and refrigeration make-up, irrigation, livestock watering and tank fill. Do not install it on a potable water supply.
