Robinet à boisseau sphérique pour eau DN 80 WKN 2a 1.6 - 4.0 MPa APA08010040250

Application and operating range in industrial installations

This reduced-bore ball valve, intended for media such as water, oils, and other non-reactive fluids with carbon steel, finds its primary application in demanding industrial environments. Thanks to certification for Group 2 fluids in accordance with Directive 97/23/EC, this component is a safe choice for district heating networks, air conditioning installations, and water supply systems. The operating temperature range from -20°C to +200°C allows installation in both cold water systems and high-temperature heating circuits. The working pressure range of 16 to 40 bar (1.6 – 4.0 MPa) makes this fitting suitable for medium- and high-pressure installations where standard solutions may be insufficient.

Construction, installation, and adaptability options

The key structural feature is the flanged connection method, which facilitates integration with existing industrial pipelines without the need for additional adapters or reducers. The valve is standardly equipped with a manual operating handle, enabling quick and intuitive manual flow control. For installers working in hard-to-reach locations or requiring greater closing torque at larger diameters (such as DN 80), the manufacturer provides modification options. The valve can be supplied with a worm gear actuator or prepared for its installation, significantly easing operation in systems with high torque requirements.

Compliance with standards and quality assurance

The product has been manufactured in accordance with standard PN-EN 12266-1 concerning the tightness of industrial valves, ensuring high reliability and minimizing the risk of leaks at critical points in the installation. The entire product is covered by a two-year warranty and holds the ŚZSJ Certificate No. 2/17 along with Declaration No. 39/AP, confirming its compliance with the rigorous requirements of the European market. It is worth noting that, thanks to the use of carbon steel as the body material, the valve exhibits the mechanical resistance necessary for harsh operating conditions while maintaining chemical compatibility with most standard media transported in industry.
