Robinet à boisseau sphérique pour eau DN 65 WKP 2a 1.6 - 4.0 MPa APA06510040160

Application and Operating Range

This flanged ball valve with nominal diameter DN 65 is designed for handling media in district heating networks, air conditioning installations, as well as water supply and industrial systems. Its construction enables safe operation with fluids classified as Group 2 under the Pressure Equipment Directive (e.g., cold and hot water, oils, glycol), which do not react chemically with carbon steel. The device is suitable for conditions requiring high pressure resistance, operating within a range of 1.6 to 4.0 MPa (16 to 40 bar). This makes it a versatile mounting component in applications where standard fittings do not meet strength requirements.

It is worth noting the wide operating temperature range, from -20°C to +200°C. This means the valve can be used in both cold water installations and heating systems with elevated medium temperatures. The full-bore ball design ensures minimal flow resistance, which is crucial for maintaining system efficiency and reducing pressure losses in the circuit.

Construction and Mounting Options

The valve is made of steel, ensuring durability and corrosion resistance in typical industrial environments. A key structural element is the mounting flanges, which facilitate quick and leak-tight installation in pipelines with a diameter of DN 65. Thanks to the full-bore design, the ball bore diameter matches the pipe diameter, eliminating the risk of clogging by contaminants and facilitating pipeline cleaning via the "pigging" method.

For installers, important information regarding actuation: the valve is standardly equipped with a handle (although in some versions it is supplied separately), but it can also be ordered with a worm gear or prepared for gear mounting. This solution allows adaptation of the fitting to specific mounting conditions or the need for remote control in hard-to-reach locations. The device weighs approximately 38 kg, requiring appropriate preparation of the support or additional reinforcement of the pipeline during installation.

Compliance with Standards and Safety

The product meets the rigorous safety requirements of the Pressure Equipment Directive PED 2014/68/EU and carries the CE marking. Leak tests were performed in accordance with standard PN-EN 12266-1, confirming high manufacturing quality and seal reliability even at maximum operating parameters. The valve is covered by a two-year manufacturer's warranty.

Key operational data include nominal diameter DN 65 made of carbon steel and an operating pressure range from 1.6 to 4.0 MPa (16–40 bar). The device operates at temperatures from -20°C to +200°C and is intended for Group 2 fluids such as water or oils. Connections are made via flanges, and the ball design is full-bore (Full bore). A 19 mm mounting key is provided for operating the standard model.

In case of replacement or servicing, ensure the system is properly depressurized before disassembling the fitting. The availability of different pressure versions for the same diameter allows precise product adaptation to a specific installation project without the need for additional reducers or adapters.
