What Duyar does

Duyar Vana Makina San. Ve Tic. A.Ş. (Duyar) is a Turkish industrial manufacturer of valves and fire-protection equipment, founded in 1965 by İdris Duyar as a metalworking workshop and now operating from Esenyurt, Istanbul. The company produces two principal product families: (1) HVAC and building-services valves — including static balancing valves (flanged, brass-threaded, grooved), ball valves, gate valves, butterfly valves, check valves, strainers, steam valves, expansion joints, and brass-group components — designed and validated using computational fluid dynamics (CFD); and (2) fire-protection systems, including UL/FM-approved sprinklers (pendent, upright, sidewall, concealed, ECLH, ELO, ESFR up to K25.2, dry barrel), wet and dry alarm valves, indicating butterfly valves, fire pumps, grooved couplings and fittings, and accessories. The company also markets an IoT-enabled Smart Valve for heating and cooling automation. All production stages from design and casting through mounting, testing, and QC are conducted in-house across seven facilities in Turkey, including an automated foundry in Beylikdüzü and a dedicated sprinkler plant in Ataşehir.

Duyar monetizes through direct hardware sales across two channels: a domestic network of 80+ authorized dealers supported by the DuyarBayi B2B portal, and direct international export to more than 85 countries through regional sales efforts, international trade fairs (e.g., Interschutz in Germany), and dedicated after-sales service. Customers span hospitals and public infrastructure (Yalova State Hospital, Basra University Education Hospital, Istanbul Airport Rescue and Fire Station, Sofia Airport, Franjo Tudjman Airport), commercial and residential real estate developers (Sinpas Gyo, NEF, Mahall Bomonti, Nida Yapı), industrial manufacturers (Volvo, Aselsan, Şişeçam, Kastamonu Integrated, Toros Tarım), retail and hospitality chains (IKEA, Bauhaus, Basra Mall, Hilton DoubleTree, Radisson Blu), and technology/defense facilities (Sparkle Data Center, Istanbul Teknopark). Cumulative installed base exceeds 800 projects. Pricing is quote-based through the B2B portal or request forms; no public price list exists.

The business is differentiated by its regulatory certification stack (UL, FM, LPCB, EAC, CE, TSE, GOST, ISO 9001/27001/10002, EFQM 4-Star) and a series of Turkish-sector firsts, including the country's first sprinkler-glass production facility (2012), first fire-products test laboratory (2013), and first dry alarm valve system (2018). The company is privately held with no disclosed external PE/VC backing and no M&A activity in its history; ownership remains founder-family anchored after nearly 60 years.
