Katup kontrol (control valve) merupakan elemen vital dalam sistem kontrol industri yang berfungsi untuk mengatur laju aliran fluida. Gangguan seperti kebocoran, stiction, clogging, dan kegagalan aktuator dapat menurunkan efisiensi proses dan mengganggu stabilitas operasi plant. Penelitian ini bertujuan merancang sistem pakar berbasis kombinasi forward chaining dan backward chaining untuk deteksi dan diagnosis kerusakan control valve. Sistem dirancang dengan basis pengetahuan berupa aturan IF-THEN yang dikembangkan dari pengalaman teknisi dan panduan manual perawatan valve. Pendekatan hybrid ini digunakan untuk memanfaatkan kelebihan forward chaining dalam deteksi cepat berdasarkan gejala, dan backward chaining untuk verifikasi mendalam terhadap hipotesis diagnosis. Pengujian fungsional sistem pada skenario kasus kerusakan Actuator Failure menunjukkan bahwa kombinasi kedua metode berhasil mencapai combined confidence 0,84 dan consistency 1,0. Integrasi kedua metode inferensi terbukti meningkatkan ketepatan diagnosis dibandingkan penggunaan satu metode saja, sehingga berpotensi untuk pemeliharaan prediktif di industri.
