This enables proportional control of fluid flow based on external signals, making these valves suitable for automation systems in HVAC, chemical dosing, or energy management. ZETKAMA’s control valves feature equal percentage flow characteristics, enhancing system stability and efficiency. The valves are available in DN15–DN150 sizes, with pressure ratings up to PN40, and body materials selected based on fluid compatibility. Tested in accordance with EN 60534-4 and PED 2014/68/EU, they guarantee leakproofness class IV and can operate in temperatures from –10°C to +300°C depending on configuration.
Each project benefits from ZETKAMA’s full-cycle production process — from in-house R&D and laboratory testing, through pattern making and casting, to machining, assembly and final pressure testing. This makes the company a reliable and agile partner among industrial valve suppliers, particularly valued for its responsiveness, product range and technical support. In the competitive landscape of valve manufacturers, ZETKAMA’s ability to deliver customized valve configurations, rapid prototyping and cast iron solutions with short lead times continues to strengthen its global reputation.
In critical applications involving high pressure, high temperature, or aggressive media, ZETKAMA performs as a reliable heavy duty valves manufacturer. The company’s engineering team develops valve designs tailored to harsh operating environments, including power boilers, industrial heating systems, and pressurized process loops. These valves are made from carefully selected materials — including high-grade ductile iron, stainless steel internal elements, and corrosion-resistant coatings — to ensure durability even in the most demanding conditions.
With advanced molding, pattern-making, and core-forming facilities, ZETKAMA delivers custom cast iron solutions tailored to customer specifications. Whether producing short series or larger batches, the company supports clients with full technical documentation, dimensional accuracy and metallurgical quality assurance. From functional housings to load-bearing mechanical parts, ZETKAMA’s castings meet demanding mechanical, thermal and chemical resistance criteria, supporting clients in reducing lead times and simplifying supply chains.
Operating from its production facilities in Poland, ZETKAMA supplies OEM manufacturers, system integrators and distributors with heavy-duty, technically advanced valves that meet the highest European standards. In addition to valve production, ZETKAMA runs its own foundry, specializing in high-quality cast iron castings tailored to client requirements. This dual competence allows for full process control — from raw material to final product — ensuring consistency, reliability and long-term value across the product lifecycle.
ZETKAMA’s foundry is a strategic advantage that supports its position not only as a valve producer, but also as a specialist in cast iron castings. The company produces grey and ductile iron parts for internal valve components and for third-party clients. This integrated model ensures traceability, repeatable quality and material consistency from melt to machining. The foundry supports custom cast iron production for OEM clients in sectors such as pump manufacturing, automotive, energy and industrial machinery.
Combining the precision of a modern production facility with the legacy of decades-long engineering experience, ZETKAMA is more than just a supplier — it is a strategic partner for companies seeking industrial valve solutions and cast iron components of verified quality. With full in-house control, fast prototyping capabilities and a global distribution network, ZETKAMA continues to raise the standard among valve companies, providing reliable infrastructure for industries that build the world.
ZETKAMA’s portfolio includes a wide range of products that classify the company as a reputable hydraulic valves manufacturer. These valves are designed to withstand variable pressure conditions, temperature fluctuations and the specific dynamics of hydraulic systems. Whether integrated into district heating loops, thermal power plants, or industrial fluid networks, ZETKAMA valves are engineered to ensure minimal pressure loss, reliable flow regulation, and safe shut-off capabilities.
As a complete industrial valves manufacturer, ZETKAMA offers over 2,000 product configurations — from basic shut-off valves to complex flow control and safety devices. The assortment includes globe valves, check valves, bellow-sealed valves, strainers, butterfly valves, ball valves, knife gate valves, pressure reducing valves, and float valves. Each type is available in a variety of materials, pressure classes (PN6–PN40), and connection standards (flanged, threaded, welded).
