Mecafrance stands for robust, precise and low-maintenance valves for chemical, energy, water technology and plant engineering applications with high pressure, temperature and media resistance requirements. As a valve manufacturer, we combine the Mecafrance portfolio with engineering, modification and system integration: from the right sealing concept and actuator selection to ready-to-install delivery with documentation.
Armaturenfabrik added value: We supply fully assembled units with pneumatic/electric actuators, limit switch boxes, position indicators – on request with heating jacket/insulation and project-specific documentation (e.g. 3.1, test protocols, CE/DGRL).
Centric/eccentric designs, wafer/lug/flange; soft or metallic gaskets for a wide range of media.
2-piece/3-piece, full bore/reduced bore; ISO 5211 flange for actuators; materials and seat materials suitable for the process.
Stainless steel, steel, alloyed cast materials; EPDM, NBR, FKM, PTFE/graphite, PEEK – depending on the medium, temperature and tightness class.
Flange patterns to DIN EN 1092-1 or ASME B16.5, thread EN ISO 228, butt weld ends; ISO-5211 for automation.
Adaptation and integration into existing systems – including heating jackets and special connections.
Hygienic butterfly valves/ball valves with suitable gaskets and connections.
Corrosion-resistant fittings, ATEX options for Ex zones, precise sealing systems.
Butterfly/ball valves for hot water, steam and condensate; reliable automation.
Robust shut-off technology for supply, circuits and treatment.
Versions for high pressure and demanding media; seawater-resistant options on a project-specific basis.
ISO-5211 compatible for skids and automated systems.
Design of fitting, gasket, material and interface according to medium, p/T and standard.
Special flanges, seat/gasket material, position feedback, heating jacket/insulation – precisely matched to the process.
Valve + actuator + limit switches/solenoid valves + mounting bridge + documents – supplied ready for installation.
Sealing concepts for aggressive media, high temperatures and required leakage rates.
CE/DGRL-compliant design, clear test documents and traceability for audits.
The ball valves RA57 and RA66 are available in DN 15 to DN 200 in PN 40.
RA57 in Stahl 1.0460 and 1.0619, RA66 in Edelstahl 1.4404 and 1.4408.
On both series the ball is made of stainless steel 1.4408.
With the TF4215 seal, up to 250 °C is permissible; an HT version is available.
Flange to DIN EN 1092-1, thread to ISO 228-1 or NPT, weld ends to DIN 11850.
Supplied with a mounting flange and without a hand lever, face-to-face length to EN 558-1 series R1.
We trade in Mecafrance valves and supply from the manufacturer range. The series listed below is a recommendation from our catalogue – we can source the complete Mecafrance range, including series not listed here.
The difference between the two series is the body material: RA57 in steel, RA66 in stainless steel. Construction, nominal sizes and pressure rating are identical. Both are of three-piece construction, which allows the ball and seals to be replaced without removing the valve from the line.
| Feature | Value |
| Design | 3-piece ball valve, reduced bore, with mounting flange and without hand lever – that is, prepared for automation |
| Nominal size | DN 15 to DN 200 |
| Pressure rating | PN 40 |
| Body | RA57: steel 1.0460 or 1.0619 · RA66: stainless steel 1.4404 or 1.4408 |
| Ball | stainless steel 1.4408 |
| Seal | TF4215, also available as an HT version |
| Temperature | up to 250 °C |
| Connections | flange to DIN EN 1092-1, thread to ISO 228-1 or NPT, weld ends to DIN 11850 |
| Face-to-face length | flanged version to EN 558-1 series R1 |
The three connection types are the practical advantage of this series: the same valve can be installed in a flanged, a screwed or a welded line without having to select a different type.
As a rule we supply the Mecafrance series version. Beyond that the following is possible with Mecafrance – optional, not a precondition:
CIP/SIP-capable designs are possible with suitable materials and gaskets (e.g. FDA-compliant).
Yes, project-specific incl. actuator/peripherals and documentation.
Yes: Fitting + actuator + limit switches/solenoid valves + documents – with heating jacket/insulation on request.
Flange to DIN EN 1092-1, thread to ISO 228-1 or NPT, weld ends to DIN 11850 – plus the mounting flange for the actuator.
Defined test scopes (pressure/leakage/function), 3.1 certificates, CE/DGRL documentation and binding schedules.
