About Zlatko Salihbegovic
My name is Zlatko Salihbegovic. I am graduated Mechanical Engineer from University of Sarajevo Yugoslavia/Bosnia and Herzegovina. I used to work in Yugoslavia for KHK company, Belgium for Mannesmann, Germany for Morton Advanced Materials, USA-Louisiana for Morton Advanced Materials and Weatherford in Lafayette LA for last 20 years before retiring and starting Z-Tech Design LLC. With Weatherford I worked for gas lift division R&D department.
I hold three patents with Morton Advanced Materials in manufacturing of CVD-chemical vapor deposition Silicon Carbide technical ceramic used in semi-conductor industry patent # 6464912, two patents in CVD manufacturing of infrared materials ZnS-Zinc Sulfide, ZnSe-Zinc Selenide and infrared guided missile domes/heads patents # 6616870, 60883561.
I hold 12 patents (some of these are with my co-workers) in gas lift equipment while working for Weatherford International, patents # 107878889, 9605521, 9593554, 9010353, 7228909.
I own 5 patents with my LLC Z-Tech Design in the field of gas lift valves and gas lift mandrel designs # US11242732B2, US11686185B2, US11845120B2, US11643910B2, and one patent in marine propulsion system # US11753128B2. Go to google patents to see all patents under my name.
I am fluent in 3 native languages, Bosnian, Croatian Serbian, German, Russian and English.
Z-Tech provides unique highly advanced and the best gas lift valve designs based on my 20 years in the field experience and multiple patents.
There are no gas lift valve designs on the market today that offer better bellow protection against high dome and injection pressure.
Our patented TSMS™-two simultaneous mechanical stop principle provides gas lift design that eliminates high differential pressure across bellows limiting it to max 250 PSI.
Our patented single and double Fortress seal™ gas lift valve design completely protects bellow from both high injection and dome pressure eliminating need for dummy valves to test well integrity.
Our patented ultra high pressure DEWB-dual edge welded bellow design provides close to zero differential pressure across the bellows. Valve is rated to 10KSI dome pressure.
Our patented SEWB-single edge welded bellow gas lift valve with injection side Fortress seal™ and TSMS provides bellow protection from both high injection and dome pressure. Valve is rated for 5000 PSI dome pressure
