Pengaturan katup pada kepala sumur panas bumi berperan penting dalam mengontrol aliran dua fasa dan efisiensi produksi, namun penelitian tentang hubungan pengaturan katup dengan parameter operasional di Indonesia masih terbatas. Penelitian ini menganalisis pengaruh pengaturan Master Valve, Wings Valve, dan Throttle Valve terhadap tekanan kepala sumur (TKS), tekanan pipa dua fasa, dan temperatur pada Sumur ZAS di lapangan panas bumi Jawa Barat. Data dikumpulkan dari tanggal 13-21 September 2024 dengan pengukuran setiap jam yang meliputi posisi katup, tekanan, temperatur, level brine, dan pH fluida. Analisis menggunakan statistik deskriptif, koefisien korelasi Pearson, dan perbandingan performa pada berbagai pengaturan katup. Hasil menunjukkan hubungan negatif yang kuat antara tekanan dan temperatur (r = -0.74), yang menunjukkan karakteristik aliran dua fasa yang dipengaruhi proses flashing. Pengaturan katup optimal adalah Master Valve 100%, Wings Valve 80%, dan Throttle Valve 100%, yang menghasilkan kestabilan terbaik dengan tekanan kepala sumur rata-rata 2.66 barg dan temperatur 123.6°C. Hasil ini dapat digunakan sebagai panduan operasional untuk meningkatkan keandalan operasi sumur panas bumi dan mengurangi risiko pembentukan kerak mineral.
