Perancangan dan Realisasi Sistem Aktuator Valve Berbasis Impact Drill untuk Meningkatkan Efesiensi Pengoperasian Katup Manual Berukuran 20 Inchi

Abstract

In the oil and gas industry, the operation of large-sized valves is still predominantly performed manually, requiring considerable time, labor, and manpower. This condition often leads to operational inefficiencies and increases occupational safety risks, particularly during shutdown, start-up, and preventive maintenance activities. This study aims to design, develop, and evaluate an impact drill–based valve actuator system as an auxiliary driving solution that is economical and does not require conversion to a fully automated system. The research methodology includes mechanical adapter design, material strength analysis, and performance testing of the actuator system during valve operation. The system utilizes an impact drill Makita with a maximum torque of 1,250 lb-in and a rotational speed of 2,100 rpm, connected to a 4 mm–thick adapter made of S235 carbon steel. The mechanical analysis results indicate that the maximum shear stress reaches approximately ±52 MPa, which remains well below the material yield strength of 235 MPa, resulting in a safety factor of about 4.5. Performance testing demonstrates that the proposed system significantly reduces valve operation time, achieving an average time efficiency improvement of 53% compared to manual operation, while also reducing operator workload. Based on these results, the impact drill–based valve actuator system is considered effective, safe, and feasible for implementation in the oil and gas industry to enhance operational efficiency and occupational safety.
