Injap rama-rama ialah sejenis injap suku pusingan yang digunakan untuk mengawal selia, mengasingkan atau memulakan dan menghentikan aliran bendalir dalam sistem paip. Ia terdiri daripada cakera bulat atau plat yang dipasang pada aci berputar. Apabila pemegang atau penggerak memusingkan aci 90 darjah, cakera bergerak dari kedudukan tertutup sepenuhnya kepada kedudukan terbuka sepenuhnya, membenarkan aliran melalui injap. Cakera kekal dalam laluan aliran walaupun dibuka, yang bermaksud sentiasa ada penurunan tekanan sedikit. Injap rama-rama terkenal dengan reka bentuk yang padat, operasi pantas dan keberkesanan kos, terutamanya dalam saluran paip berdiameter besar. Ia datang dalam pelbagai jenis, seperti wafer, lug dan gaya mengimbangi dua atau tiga kali ganda, bergantung pada tekanan dan keperluan pengedap. Injap ini digunakan secara meluas dalam industri seperti rawatan air, HVAC, pemprosesan kimia, minyak dan gas, dan makanan dan minuman, kerana kebolehpercayaannya, penyelenggaraan yang rendah, dan pemasangan yang mudah.
