Float valves
A very effective solution for controlling the liquid level, which does not require any external energy. Float valves are purely mechanical – the water level is measured directly by the lever with a gas-filled container attached at the end. The lever indicates the positioning of the internal mechanism controlling the flow, therefore regulating the volume of liquid in a vessel. Such components can be installed in both open and sealed tanks and cisterns – their primary function is to actively prevent overflowing.
zFLO – industrial float valves
The external shell of the components is made of grey cast iron – it ensures sufficient durability and tightness, capable of withstanding nominal pressure of 10 bars. It requires no maintenance whatsoever, at the same time being completely eco-friendly due to the lack of power consumption. The mechanism is fit to work with industrial water and neutral fluids. The main fields, in which such components are applied, are domestic water systems, as well as agricultural and industrial installations.

Why float valves are essential for modern fluid systems
Float valves play a critical role in maintaining precise liquid levels in tanks, reservoirs, and storage vessels across industrial, commercial, and agricultural applications. Operated solely by the mechanical movement of a float, float valves require no external power, ensuring reliable and energy-efficient control. A high-quality water float valve guarantees continuous performance by automatically opening or closing based on the liquid level, thus protecting equipment and optimizing system functionality with minimal intervention.
Industrial float valves designed for demanding environments
Zetkama’s industrial float valves are engineered to meet the requirements of various industries where consistent liquid level control is vital. Manufactured in nominal diameters ranging from DN 25 to DN 200 and rated for pressures up to 10 bar, these valves operate effectively within a temperature range from -10°C to +90°C. Constructed from grey cast iron for strength and resistance to corrosion, and featuring stainless steel discs and stems, Zetkama’s float valves offer outstanding durability and sealing reliability. EPDM gaskets and coated steel floats ensure long service life, even in aggressive or variable environmental conditions.
Heavy duty float valve solutions for large-scale applications
For applications that demand enhanced mechanical resilience and long operational life, Zetkama offers a range of heavy duty float valves. Equipped with reinforced piston sleeves — brass for smaller sizes and bronze for larger sizes — and protected by durable epoxy coatings, these valves are built to withstand intensive use. A heavy duty float valve provides the strength needed for challenging operations, such as industrial water management systems, large agricultural reservoirs, and process industry tanks, delivering dependable performance under continuous service.
Key material advantages of Zetkama water float valves
Every water float valve from Zetkama is designed with materials carefully selected for maximum performance. Grey cast iron bodies offer excellent mechanical resistance, while stainless steel components enhance durability against corrosion. EPDM sealing elements provide exceptional leak-tightness, ensuring consistent and efficient valve operation over time. Coated steel floats prevent damage from water and chemical exposure, guaranteeing reliability across a wide range of media types and environmental conditions. Together, these features make Zetkama’s float valves the ideal choice for maintenance-free, long-term fluid level control.
Typical applications of industrial and heavy duty float valves
Industrial float valves are indispensable in numerous sectors. In industrial water systems, they maintain optimal levels in tanks and reservoirs, ensuring smooth process operations. In neutral fluid systems, they reliably manage non-aggressive liquids where material compatibility is crucial. In agriculture and irrigation, float valves control water distribution efficiently, reducing manual intervention and protecting crops. Domestic and commercial water supply systems also rely on float valves for safe and consistent water storage. Whether in open reservoirs or closed tank installations, Zetkama’s float valves guarantee operational stability and system protection.
Operational features and installation benefits
Zetkama float valves operate purely through mechanical float movement, opening or closing based on the liquid’s rise or fall. This eliminates the need for external energy inputs, resulting in zero operational power consumption and significantly lower environmental impact. Their simple mechanical design ensures minimal maintenance requirements and easy adjustment to different tank sizes and system specifications. Designed primarily for horizontal installation, the float mechanism can be fine-tuned for various applications. Manufactured according to strict European EN standards, Zetkama float valves deliver maximum reliability, durability, and compatibility across diverse fluid management systems.
