Ball valves
Durable construction combined with a very simple principle of operation. The ball valve’s primary component is a handle that is used to control the flow through the system. The internal work piece is made in the shape of a perforated sphere. When placed in its starting position – both the handle and hollow part are aligned with the pipe – the flow is released, but when it is pivoted by 90 degrees, the internal sphere is turned sideways to block any flowing liquid or gas. The movement of the handle is also a great visual indication of the component’s status (open or closed).
Ball valve – ZETKAMA zBAL
As for the construction of this component – it is made of durable combination of grey and nodular cast iron. The work piece itself is brass with additional chrome coating – it does not generate any added resistance to the installation. Its ease of operation and versatility has led to the extensive industrial use of this type of elements. It is fit for work within various heating systems, industrial water and other neutral fluids, as well as pressurized gas.

Why choose Zetkama industrial ball valves?
Zetkama’s zBAL series ball valves offer robust and precise flow control across a wide range of industrial systems. Known for their compact design, tight shut-off, and corrosion-resistant materials, these valves provide long-term reliability even in demanding operating environments. Whether you need a stainless steel ball valve for aggressive media or a brass ball valve for standard applications, the zBAL range delivers consistent performance with minimal maintenance requirements.
Technical capabilities of ball valves
Zetkama ball valves are available in nominal diameters from DN 15 to DN 250 and pressure ratings of PN 10 and PN 16. Operating temperatures range from -30°C to +220°C, depending on material configuration. The body is made from grey cast iron, ductile iron, or cast stainless steel, with a precision-machined AISI 304 stainless ball. The PTFE seat and stainless steel stem ensure smooth operation and high chemical resistance. Flanged end connections follow EN 1092-1/-2 standards, and all valves meet Class A leakage criteria per EN 12266-1. Models from DN 32 upwards are CE-certified under the Pressure Equipment Directive 2014/68/EU.
Material quality and sealing performance
Each stainless ball valve in the zBAL series is designed for durability and reliability. Corrosion-resistant materials like PTFE and stainless steel ensure safe operation with various fluids. EPDM or FKM sealing rings provide flexibility for different media, maintaining leak-tight performance even under fluctuating pressure and temperature conditions. The valve’s high-quality internals allow for smooth, consistent operation and reduced wear over time.
Key applications of high pressure ball valves
Zetkama industrial ball valves are versatile, supporting fluid control across multiple sectors:
- Water and Utility Systems: Reliable shut-off and flow control in water distribution and industrial water systems.
- HVAC Installations: Regulation of heating and cooling circuits.
- Compressed Air Networks: Preventing backflow and managing pressurized air.
- Marine Industry: Corrosion-resistant stainless ball valves suitable for harsh marine environments.
- Chemical and Petrochemical Processing: Safe operation with aggressive and hazardous substances.
- Power Engineering: High pressure ball valves that perform in steam and thermal oil systems.
Operational features and advantages
The zBAL ball valves are available in manually operated versions with a lever and are also compatible with electric or pneumatic actuators for automated systems. A visual position indicator ensures clear visibility of open or closed valve status. Designed with serviceability in mind, the valves feature accessible internals and standard components that simplify maintenance. The compact and rugged construction supports versatile installation across pipelines with limited space.
