SISTO Armaturen

What SISTO Armaturen does

SISTO Armaturen S.A. is a Luxembourg-based industrial manufacturer specializing in stainless steel diaphragm valves for sterile and aseptic process engineering. Founded in 1924 (originally as Fonderie et Ateliers de Mersch / FAM), the company operates a single production site in Echternach with approximately 200 employees and has been an associate company of the KSB Group since 1988, alongside the Luxembourg state development bank SNCI. SISTO serves pharmaceutical, biotechnology, and food industry customers requiring maximum sterility in fluid handling for applications such as vaccine, insulin, enzyme, and active pharmaceutical ingredient production.

The company's core technology centers on a proprietary chambered sealing system (introduced 1980) in which the diaphragm is held within a valve body chamber and supported by a flexible metal spiral spring, preventing deformation under temperature and prolonging service life. In 2022, SISTO became the first manufacturer globally to launch fully 3D-printed diaphragm valves for pharmaceutical applications, using TÜV-certified additive manufacturing (powder bed fusion / laser melting) with access to KSB's AM expertise. The product portfolio spans 2-way, T-, Y-, multiport, and tank valves (DN 6 to DN 300, up to 20 bar), supported by high vertical integration at Echternach including in-house mechanical production, diaphragm manufacturing, and electropolishing.

SISTO operates a B2B enterprise field sales model, engaging directly with engineering and procurement teams at pharmaceutical and biotech manufacturers on a project basis from initial enquiry through custom 3D modeling, manufacturing, and delivery. Pricing is quote-based and not publicly disclosed; revenue is generated primarily through one-time sales of valves and components (with multi-year contracts referenced). Demand generation relies on European trade show participation (ILMAC Basel, Farmaforum Madrid, Pharma Congress Wiesbaden, Lounges Karlsruhe), a multilingual corporate website with downloadable catalogs and CAD models, an installation-angle smartphone app, and 100-year heritage marketing. Certifications span ISO 9001/14001/45001, PED 2014/68/EU (Module H), AD2000, FDA, EU 1935/2004, USP, and ATEX.

Products and services

• SISTO-C 2-Way Diaphragm Valves Standard two-way stainless steel diaphragm valves for sterile and aseptic pharmaceutical, biotechnology, and food applications. Used as shut-off and control valves in CIP/SIP processes with the proprietary chambered sealing system.
• SISTO-C T-Valves and Y-Valves T-valves and Y-valves for diverting or combining flow paths in sterile process lines in pharmaceutical and food plants. Built on the chambered sealing system platform.
• SISTO-C Multiport Valves Custom multiport diaphragm valves designed and manufactured to customer-specific process layouts, reducing fluid-contact surface area, deadleg, contamination risk, and plant footprint versus conventional welded or ring designs.
• SISTO-C Tank Valves Tank-bottom diaphragm valves engineered for sterile vessels used in pharmaceutical and food processing, providing complete draining capability with no deadleg and laser-marked drain angles for correct installation.
• SISTO Actuators Pneumatic actuators for automated operation of SISTO diaphragm valves, with universal diaphragm philosophy and standardised fixing across diaphragm types.
• SISTO Diaphragms Replacement and OEM diaphragms (EPDM, TFM/EPDM and other elastomers) for SISTO diaphragm valves. Designed for maximum service life with FDA, EU 1935/2004, and USP compliance for pharmaceutical and food contact applications.
• SISTO Valve Accessories Accessory components supporting SISTO diaphragm valve installations in sterile process lines.
• SISTO-C Additiv (3D-Printed Diaphragm Valves) Fully additively manufactured stainless steel diaphragm valves for pharmaceutical and biotechnology applications, produced via powder-bed fusion (laser melting). Enables high-quality nickel alloys, shorter delivery times, weight/space savings, and high design flexibility. Already supplied to one of the largest German pharmaceutical companies.
• SISTO-SK-i.310 Position Transmitter Third-generation position transmitter providing valve position feedback and monitoring on SISTO diaphragm valves, with enhanced features for process automation.
• Industrial, Building Services and Energy Technology Valves Stainless steel diaphragm and related valves for industrial process engineering, building services, and energy technology applications, including green hydrogen production valve solutions.
