Robinet à boisseau sphérique pour eau DN 25 WKN 2a 1.6 - 4.0 MPa APA02510040250

Application in industrial and district heating installations

This reduced-bore ball valve, designed for DN 25, is a key component for the stable operation of district heating networks, air conditioning systems, and water supply installations. Its construction enables safe control of the flow of water, oils, and other media that do not react with carbon steel. Thanks to its resistance to temperatures ranging from -20°C to +200°C, the device is suitable for both cold outdoor installations and heating circuits with elevated operating temperatures.

It is important to note the pressure range in which the valve maintains full tightness and durability. The device operates effectively at a working pressure (PS) from 16 to 40 bar (1.6 – 4.0 MPa), making it a universal solution for medium- and high-pressure installations. Compliance with the PN-EN 12266-1 standard and possession of the ŚZSJ certificate No. 2/17 (declaration number 39/AP) confirm its suitability for professional industrial applications requiring high reliability and compliance with the PED directive (97/23/EC) for fluids of Group 2.

Construction and mounting possibilities

A key element of this fitting is its flanged design, which facilitates integration with existing pipeline systems without the need for additional adapters or reducers. The valve is equipped with a standard handle for manual control, allowing quick and intuitive closure or opening of the flow during maintenance or emergencies. For installers working in hard-to-reach locations or requiring precise flow throttling, the manufacturer offers an optional version with a worm gear or preparation for mounting an electric/pneumatic actuator.

Thanks to its reduced bore, this valve not only fulfills its shut-off functions but also optimizes mounting space in dense valve assemblies. It is a solution designed to withstand operating conditions in challenging industrial environments, ensuring long-term tightness while maintaining ease of operation. The standard version with a handle is ready for immediate installation after verifying the tightness of the flanged connections.
