Description

In industrial and civilian water storage systems, the 50mm float valve (DN50 float valve) serves as the core component for automatic liquid level regulation. Driven by the rise and fall of the float ball linked to a connecting rod mechanism, the valve opens and closes automatically to carry out automatic water level control and govern the water inflow of water tanks, water towers and storage tanks.
Different from conventional ball valves requiring manual operation, this float ball valve for water tank adjusts itself entirely according to liquid level variations. It drastically cuts manual maintenance costs and prevents water overflow or water shortage failures effectively.
Our DN50 ball float valve for water tank features a valve body cast from premium brass or stainless steel, delivering outstanding corrosion resistance and mechanical strength. Its float adopts hollow stainless steel or engineering plastic construction, resisting rust and permanent deformation even under long-term water immersion.
The sealing assembly of the valve core is made of nitrile rubber (NBR) or ethylene propylene diene monomer (EPDM), maintaining zero-leakage sealing performance during repeated frequent opening and closing cycles. It fits perfectly for drinking water, industrial circulating water, fire protection water storage tanks and other scenarios.

 

While evaluating 50mm float valve price, we fully understand purchasers care not only about unit procurement cost, but also delivery timeliness and customization flexibility. As a direct manufacturer, we bring these core benefits to clients:

Fast Delivery & In Stock: Regular DN50 (PN10/PN16) specifications are always stocked in large quantities. Standard orders can be shipped within 3 working days, and expedited shipment is available for urgent projects.
Customizable & OEM Service: Customization is supported in valve body material (brass/stainless steel/cast iron), connection type (thread/flange), float material and water inlet mode (side inlet/bottom inlet). OEM private labeling is available upon your working condition requirements.
Strict Quality Control: Every product undergoes shell strength testing at 1.5 times nominal pressure and tightness testing at 1.1 times nominal pressure before shipment, guaranteeing stable operation right after on-site installation.

Besides, our float ball valves for irrigation systems can be equipped with side-mounted or top-mounted float assemblies to accommodate varied installation spaces for large irrigation projects and industrial cooling tower systems. For high-rise building water tanks and high-pressure working conditions, slow-closing or balanced float valve structures are optional to eliminate water hammer and extend the service life of valves and pipeline systems further.

 FAQ for Overseas Buyers

Q1: What main factors affect 50mm float valve price? Can your company supply samples or small trial orders?
A1: Pricing is mainly determined by four aspects: (1) valve body material (stainless steel > brass > cast iron);( 2) connection form, flanged versions are generally priced higher than threaded types; (3) sealing material, high-temperature resistant EPDM is slightly more expensive than NBR; (4) material and dimension of the float. Sample orders ranging from 1 to 5 pieces are acceptable; samples are charged at bulk pricing with fast delivery included. Once bulk orders are confirmed after trial use, the price difference of samples will be refunded accordingly.
Q2: Is your DN50 float valve applicable for high-pressure working conditions such as water supply in high-rise buildings?
A2: Our standard version is rated PN16, suitable for most regular building heights. For high-rise buildings or working conditions behind high-lift pumps, we supply reinforced float valves rated PN25 with thicker valve walls and reinforced sealing assemblies, ensuring stable opening and closing under working pressure exceeding 1.6 MPa. When sending inquiries, kindly provide the actual working pressure and installation height, and our technical team will recommend the optimal model solution for you.
