What Zamkon does

Zamkon (legal entity ZAMKON Armatura i Technologie Sp. z o.o., with affiliated partnership Przedsiębiorstwo Produkcji Armatury Zamkon W.ZAMCZEWSKI i S-KA Sp.j) is a privately held Polish manufacturer of industrial valves, steam traps, and turnkey flow-control systems, founded in 1989 and headquartered in Kędzierzyn-Koźle. The company operates three sites in Kędzierzyn-Koźle: a commercial and design office plus production plant at ul. Jana Cybisa 23, a logistics and production plant at ul. Mostowa 35A, and an R&D department at ul. Mostowa 35. Its product portfolio spans steam traps (bell, float, bimetal, thermodynamic, pumping variants), wedge gate valves, centric, triple-offset (Z3M) and quadruple-offset (Quadax) butterfly valves for cryogenic applications, ball valves, bellows-sealed valves (ZZM), filters, steam and gas separators, and pressure-reducing valves, alongside complete installation systems such as reduction-cooling stations, condensate pumping stations (WZZ), and gas metering stations. Services include CNC machining, pressure-equipment modernization, actuator installation and setup, industrial installation design, steam-trap inspections, valve servicing, training, and industrial installation execution. Zamkon also holds the exclusive Polish distributorship for ARI (Ari-Armaturen) products.

The company sells through direct commercial and design office contact and a website inquiry form, with prices quoted per project against specifications ranging DN6-DN1000 and PN2.5-PN630. Customer segments are vertically oriented, covering power and heating plants, chemical and petrochemical facilities, refineries (including coke chemistry), hydropower plants, and — under active exploration — the Polish nuclear power supply chain. The company is led by CEO Monika Zamczewska-Zjawiony, with founder Waldemar Zamczewski associated with the ownership structure; the firm is a member of the Polish Heat Industry Association (SPAP) and has secured approximately 6.45M PLN in EU co-financing, including funding for an R&D center construction project valued at 10.99M PLN and an R&D initiative launched in December 2024 to develop a wedge gate valve capable of installation and operation at any angle on industrial systems.

• Velan Inc. Canadian manufacturer of industrial valves (gate, globe, check, butterfly, ball, specialty) for severe-service applications in power, oil & gas, chemical, and pulp & paper. Directly comparable to Zamkon in producing high-specification metal-seated and severe-service valves for similar industrial customers.
• Polna Śląsk Sp. z o.o. Polish industrial valve manufacturer with a broadly overlapping product range (gate, globe, check, safety, and control valves) serving power, chemical, heating, and process industries. Already a named technology partner of Zamkon, the two compete head-to-head in the Polish industrial valve market with similar customer profiles and pricing structures.
• AVK Holding A/S: Danish group manufacturing a wide range of valves for water, gas, and industrial applications, with strong presence across Europe. Closely comparable to Zamkon in product breadth (gate, butterfly, check, control valves) and in targeting industrial, municipal, and energy customers in European markets.
