Acid-resistant ball valve DN 80 WKK 2a 1.6 MPa APA08060016040

Application and Operating Conditions

The valve is designed for controlling the flow of aggressive media — such as acids, alkalis, salts, or other chemical industrial fluids — in accordance with the corrosion resistance tables for stainless steel grades 304 or 316L. It operates safely in district heating systems, water supply networks, and industrial installations where corrosion resistance is required. It functions within a temperature range of -20°C to +160°C, enabling its use in both low-temperature processes and high-temperature flow systems.

Construction and Compliance

Constructed from chemically resistant materials, the valve complies with standard PN-EN 12266-1 regarding tightness and strength testing of valves. The maximum working pressure is 16 bar (1.6 MPa) — a value confirmed by the manufacturer and independent of search results. The ŚZSJ Certificate No. 2/17 guarantees compliance with Polish safety requirements for industrial valves. The standard version is equipped with a manual operating handle; a version with a worm gear reducer or ready for its installation is also available — facilitating operation in hard-to-reach locations.

Benefits for the Installer and User

• Requires minimal maintenance due to corrosion resistance — reduces operating costs.
• Operates stably at high temperatures — maintains tightness even at 160°C.
• Simple installation: standard threaded or flanged connections.
• The version with a worm gear reducer allows precise flow regulation — useful where flow control is needed without manual force.
• The ŚZSJ certificate indicates that the valve can be used in installations requiring safety confirmation by supervisory authorities.
