LDM VALVES

What LDM VALVES does

LDM VALVES (L D M, spol. s r.o.) is a Czech private industrial valve manufacturer headquartered in Česká Třebová, tracing its heritage to valve production that began in 1909 and formally incorporated in 1991. The company designs, manufactures, and services control valves, shut-off valves, safety valves, pressure and temperature regulators, nuclear power valves, and steam desuperheating equipment across a nominal diameter range of DN 10 to DN 600 and pressure ratings from PN 6 to PN 630. Its product portfolio includes proprietary series such as the 111 COMAR, 122 BEE, 200, 300, 700, 800, 900, and G lines for control valves, the UV/SV series for shut-off isolation, the A10/A11/A13 series for nuclear plants, and the VH/CHP series for steam conditioning. Manufacturing is supported by in-house galvanizing and CNC machining capability (up to 25 tonnes), and the company is certified to ISO 9001, ISO 14001, and ISO 45001.

The company makes money primarily through hardware sales of industrial valves, with secondary revenue from after-sales service (via subsidiary LDM servis), galvanizing and CNC machining services to external customers, and quotation-based project pricing. Go-to-market is a hybrid model combining direct domestic and export sales teams, wholly-owned subsidiaries in Slovakia, Poland, Bulgaria, Russia, and Kazakhstan, sales representation in Germany, and authorized dealer networks (15+ in the Czech Republic, 20+ in Poland). LDM supports its portfolio with free calculation software (Ventily LDM desktop program and LDM VALVES mobile app in eight languages) and downloadable CAD documentation. Customers span nuclear power generation (Temelín, Dukovany, Mochovce, Bohunice, Paks, Kozloduy), conventional energy (ČEZ, Slovenské elektrárne), general industrial manufacturing, and district heating/HVAC.

The company is privately held by its founders with no venture capital or private equity backing disclosed, employs more than 220 staff, and operates with integrated management system certifications. LDM is qualified as a supplier to ČEZ (2024-2026) and Slovenské elektrárne, and supplies safety-critical nuclear valves with seismic-resistant (SP) execution to multiple European nuclear plants. Revenue is not publicly disclosed.
