柱塞截止閥其實還是屬于截止閥中的一種，是常規截止閥的變型，閥瓣和閥座采用柱塞原理設計，其公稱壓力有1.6MPa、2.5MPa、4.0MPa、6.4MPa、10.0MPa，口徑大小有DN15、DN20、DN25、DN32、DN40、DN50、DN65、DN80、DN100、DN125、DN150、DN200等等。

柱塞截止閥型號:

柱塞截止閥常見的基本型號有UJ41W、UJ41H、UJ41Y等，若加上公稱壓力和閥體材質，則較為常見的型號如下所示：

UJ41W-16C、UJ41W-25C、UJ41W-40C、UJ41W-16R、UJ41W-25R、UJ41W-40R、UJ41W-16P、UJ41W-25P、UJ41W-40P。
