Ball valve water DN 25 WKP 2a 1.6 - 4.0 MPa APA02510040160

Application and Scope of Work in Industrial Installations

This full-bore flanged ball valve DN 25 is designed for operation in demanding conditions of district heating networks, water supply installations, and air conditioning systems. Its construction enables safe control of the flow of water, oils, and other media non-reactive with carbon steel (Group 2 fluids according to Directive 97/23/EC). Thanks to a wide range of operating pressures, from 1.6 to 4.0 MPa (from 16 to 40 bar), this component is suitable for both standard circuits and high-pressure installations. The operating temperature range from -20°C to +200°C makes it a universal solution for heating and technological systems where environmental conditions may undergo significant fluctuations.

Construction and Mounting Capabilities

The key feature of this model is the full bore, which minimizes flow resistance and prevents the accumulation of contaminants inside the body – which is particularly important for long-term operation in water installations. The valve is equipped with a standard operating handle, facilitating quick and intuitive operation during installation or maintenance. For installers, mounting flexibility is also crucial: a version with a worm gear reducer is available or prepared for an actuator drive, allowing easy integration with building automation systems. Flanged connections ensure joint rigidity and sealing reliability in challenging industrial conditions.

Compliance with Standards and Durability

The product meets the rigorous requirements of standard PN-EN 12266-1, guaranteeing its tightness and reliability during pressure tests. The steel body construction ensures resistance to corrosion and mechanical damage typical of industrial environments.

In practice, this means that the valve with a nominal diameter of DN 25 fits perfectly into standard pipe connections of medium-sized industrial installations. Its ability to operate at pressures from 16 to 40 bar (i.e., 1.6 – 4.0 MPa) allows adaptation to various network loads without risk of damage. Thanks to the extensive operating temperature range, covering the interval from -20°C to +200°C, the device is suitable for both cold water systems and hot heating circuits. The full-bore flanged construction not only facilitates flow but also minimizes pressure losses at full opening. The entire production process and the tightness of components are confirmed by compliance with standard PN-EN 12266-1.
