The Mecafrance RA57 and RA66 ball valves are based on a flexible, modular concept that allows easy adaptation to different process requirements. Thanks to the intelligent design, different connection types such as butt weld ends, flange connections or threaded connections can be easily selected or retrofitted – without having to replace the entire ball valve.

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.
Optimize your processes with heatable valves: heating jackets, leakage jackets or double jacket versions ensure temperature-stable media flow, prevent solidification and enable safe and efficient production processes. Ideal for ball valves, valves, filters and strainers in the chemical, food and process industries.
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.
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.
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.
Both types are designed for PN40.
Yes, both types have ISO 5211 mounting flanges for pneumatic or electric actuators.
ATEX, TA-Luft, CE, Fire-Safe according to BS 6755.
Water, oil, gas, steam, chemicals, food media.
Yes, e.g. with high-temperature gaskets, stem extensions or special connection variants.
Our insulations are more than just accessories – they perfectly complement fittings and systems and increase efficiency, safety and adaptability.
