Mabuku Owerengera
Ma Valves a Hikelok-Block ndi Bleed
ChiyambiKuphatikiza kwapadera kwa Hikelok kwa ma double block ndi bleed valve systems kumathandiza kusintha kosalala kuchokera ku processing piping system kupita ku zida, kupereka malo ochepa otayira madzi, kulemera kochepa, ndi malo ochepa. Block ndi Bleed Valves amapangidwira malo otayira madzi, kuyika mwachindunji ku zida, kulumikizana kwa zida, double block ndi bleed isolation, ma vents ndi drains
