Dikkaya Su Kontrol Sistemleri San. ve Tic. A.S
About
DKY Valves and Controls, the brand of Dikkaya Su Kontrol Sistemleri Sanayi ve Ticaret A.S., was founded in 1997 in Kemalpasa, Izmir, Turkey, and operates from a 7,000-square-meter indoor production facility. Originally established as a distributor for international valve brands, DKY began manufacturing its own patented valve designs in 2001 and now produces a comprehensive product line for water infrastructure, agricultural irrigation, and fire protection. The hydraulic control valve range includes models for level control (0010), pump protection (0020), solenoid operation (0030), pressure reducing (0060), flow regulation (0070), pressure sustaining and relief (0080), and surge anticipation (0088). Air valves are offered in double-chamber and single-chamber configurations, including dirty water variants for wastewater service. On the technology side, the e-Pilot electronic control system enables smart remote valve operation, the ultrasonic water meter provides transit-time flow measurement, and the HydroNYX platform addresses water loss and leakage prevention across distribution networks. Isolation valve offerings encompass elastomer-seated gate valves, double-eccentric butterfly valves, swing and tilting check valves, Y-type and basket strainers, and dismantling pieces. DKY also manufactures agricultural irrigation hydrants (Types DKH and HSH) and above-ground fire hydrants (Types A and C, including a breakable model). Every valve undergoes 100 percent hydrostatic pressure testing before shipment, and the company holds ISO 9001, OHSAS 18001, ISO 14001, CE, and EAC certifications.
Key Products
