Cast steel / stainless steel, PN 40, flanged ball valve, can be automated
The flanged ball valves 71 MS and 71 ME from BEE are high-grade industrial valves for demanding applications. They offer maximum safety, a standard-compliant design and a long service life.
71 MS: In cast steel for standard industrial applications.
71 ME: In stainless steel for corrosion-critical media and aggressive environments.
Both versions are fire-safe, maintenance-free and have a blow-out proof stem as well as an ISO 5211 mounting flange for automation.
Besides the material, the face-to-face length is the second decision: R1 and R27 to DIN EN 558 differ in installation length and must be checked when replacing. Both versions cover PN 16 and PN 40.

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.
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.
71 MS is made of cast steel for standard applications, 71 ME of stainless steel for corrosion-critical media.
DIN EN 558, ISO 5211, PED, TA-Luft, LABS-compliant.
Yes, both variants have an ISO 5211 mounting flange for electric or pneumatic actuators.
