Dklok

DK-Lok (Korean: 디케이락) designs and manufactures precision components for industrial fluid and gas handling systems. Its catalogue is organised into instrumentation products (fittings, valves, quick connects, tube and hose), semiconductor-oriented products (fittings, valves, regulators, integrated gas systems) and process products (check valves, globe valves, gate valves, ball valves). The company positions its engineering around durability, corrosion resistance, leak-tightness and compatibility, and frames its product development around shifts in the energy mix, including alternative and green energy applications.

End markets addressed include oil and gas, refining and chemicals, power generation and EPC, shipbuilding and offshore, machinery and equipment, CNG/RNG/NGV, hydrogen, semiconductors and displays, and aerospace and defense.

In the United States the business is represented by DK-LOK USA, based in Mobile, Alabama, which supplies quick release couplings for instrumentation, hydraulic, pneumatic and process applications, along with complementary tube fittings, valves and fluid handling components. That operation describes couplings built to tight tolerances and durable materials for high-pressure and high-purity systems exposed to vibration, temperature extremes and corrosive media, and offers technical support covering product selection, application guidance and system optimisation for both new installations and retrofits.

Business model

The company manufactures and sells fluid system hardware, distributing through a dealer and distributor network and supplying engineers, OEMs and maintenance organisations directly with product plus application engineering support [0][1].

Traction

The distribution network spans 124 dealers in 45 countries, and the product range extends from traditional oil, gas and refining applications into hydrogen, semiconductor and alternative-energy markets [0].
