Injap pintu ialah sejenis injap yang digunakan untuk menghentikan sepenuhnya atau membenarkan aliran dalam saluran paip dengan menaikkan atau menurunkan penghalang pepejal (pintu gerbang) ke dalam laluan bendalir. Ia direka terutamanya untuk kawalan hidup/mati dan bukannya peraturan aliran. Apabila injap terbuka sepenuhnya, pintu pagar terangkat sepenuhnya, membenarkan aliran tanpa halangan dengan penurunan tekanan yang minimum. Apabila ditutup, pintu pagar ditutup rapat untuk menghentikan aliran sepenuhnya. Injap pintu adalah paling berkesan dalam sistem di mana injap kekal sama ada terbuka sepenuhnya atau tertutup sepenuhnya untuk tempoh yang lama. Ia tidak sesuai untuk tujuan pendikitan kerana pintu separa terbuka boleh bergetar, menyebabkan haus dan berpotensi merosakkan injap. Injap ini digunakan secara meluas dalam sistem bekalan air, saluran paip minyak dan gas, dan aplikasi perindustrian kerana pembinaannya yang teguh dan keupayaan untuk mengendalikan tekanan dan suhu tinggi. Bahan biasa termasuk besi tuang, keluli tahan karat dan loyang, dengan pilihan yang disesuaikan dengan media dan persekitaran tertentu. Injap pintu terkenal dengan ketahanannya, pengedap yang ketat dan hayat perkhidmatan yang panjang, menjadikannya pilihan utama dalam banyak aplikasi tugas berat.
