District heating ball valve, various connection options, PN 40
The Vexve ball valves types 100, 101, 103 and 104 have been specially developed for demanding applications in district heating technology. They are characterized by their robust design, high pressure and temperature resistance as well as flexible connection options.
Types 103 and 104 are available as flanged ball valves and are ideal for district heating pipes. They offer a reduced bore, flanged connections in accordance with EN 1092-1 and are available in nominal pressures PN 10, 16, 25 and 40. Variants with manual gearboxes and optional electric or hydraulic actuators are available for large nominal sizes (DN 65-500).
Types 100 and 101 complete the portfolio with butt weld ends or female thread/weld end combinations for smaller nominal sizes (DN 10-50). All models are designed for a temperature range of -20 °C to +200 °C and comply with leakage rate A in accordance with EN 12266-1.

Maximize the functionality of your ball valves with pneumatic or electric actuators. Thanks to ISO 5211 mounting flanges, spindle extensions and mounting bridges, our valves are easy to automate – for precise control in industrial plants.
We offer professional modifications for your valves:
All work is carried out in accordance with the standard, with functional testing and optional certification (e.g. APZ 10204-3.1 B).
Benefit from customized solutions, fast implementation and the highest quality – even for the ball valves you provide.
Increase the user-friendliness of your ball valves with stem or stem extensions. This modification is ideal for isolated valves or valves that are difficult to access and enables convenient manual operation or the connection of pneumatic and electric actuators.
For all our ball valves – whether with or without heating jacket, whether in manual mode or automated by actuators – we offer the right insulation, individually manufactured.
Insulation can be implemented with the high-quality IFS-Plast25 insulating jackets and insulating pads, for example. This solution ensures optimum energy efficiency and safety in your process.
The ball valve is suitable for water, oil, gas, steam and aggressive media in industrial processes.
Yes, thanks to the ISO 5211 mounting flange, the VL-851 can be easily automated with electric or pneumatic actuators.
PN40 for DN15-50 and PN16 for DN65-100 according to DIN EN 1092-1.
Yes, the ball valve is available in a fire-safe design and meets high safety requirements.
The compact design saves space, reduces weight and facilitates installation in narrow piping areas.
Our insulations are more than just accessories – they perfectly complement fittings and systems and increase efficiency, safety and adaptability.
