## Features

- Thickened Rubber Gasket for Secure Sealing – Ideal for High Pressure Ballcock & Float Valve Reliability This float valve (a core part of any ballcock for water tank or ball cock for water tank setup) features a thickened rubber gasket paired with vertical rotation design—making it a robust high pressure ballcock that solves the common failure of float valves caused by unbalanced valve core force. It ensures the sealing mechanism of this water tank ball valve (and general ball valve) stays safe and reliable, even under high water pressure and frequent opening/closing cycles.
- Intuitive Operation Principle – Core of Ball Cock15mm Float for Water Tank & Toilet Ball Cock The DN15 float valve (matching the size of ball cock15mm float for water tank and the heart of a ballcock for water tank) controls water flow and inlet pipe opening/closing via the float’s movement. It’s also compatible with small ball float toilet, toilet ball cock, and toilet ball valve setups: when the water level (in tanks or toilets) rises to your desired height, this cold water tank ball valve automatically cuts off water injection; when the level drops, it reactivates filling.
- Premium Stainless Steel – Durable Build for Stainless Steel Ball Float & Cold Water Tank Ballcock Valve The main body of our 0.1-0.8MPa float valve (a heavy-duty water tank ball valve and cold water tank ball valve) is made from high-quality stainless steel, processed via hot forging for enhanced strength. It comes with a stainless steel ball float, ensuring the cold water tank ballcock valve and ball cock for water tank component stay stable, corrosion-resistant, and durable—withstanding daily wear, water exposure, and temperature changes without deformation or rust.
- Tailored for Water Tanks – Versatile Float Valve & Stop Ball Valve for Multiple Scenarios This 3.9-inch float valve (a dedicated water tank ball valve and ball cock15mm float for water tank companion) is designed exclusively for water storage scenarios, while also functioning as a practical stop ball valve with automatic shutoff. It fits seamlessly with water storage tanks, pools, aquariums, fish tanks, livestock sinks, aquaculture systems, and even as a backup for toilet ball valve setups.
- Complete Package – Ready-to-Install Ball Cock for Water Tank & Float Valve Ball Steel 3.9inches Kit The package includes a full set of components for your ballcock for water tank and float valve setup: a float valve ball steel 3.9inches (98mm/3.9in stainless steel ball float), a metal support rod, and a copper threaded connector. Everything you need to assemble and install this water tank ball valve (or replace an old toilet ball cock) is included—no extra parts to buy. It’s a hassle-free solution to set up your ball cock for water tank, cold water tank ballcock valve, or even a small toilet ball valve system quickly.
