Y型過濾器是輸送介質(zhì)的管道系統(tǒng)的一種裝置，通常安裝在水力控制閥或其它設(shè)備的進口端，用來清除介質(zhì)中顆粒性雜質(zhì)，以保護閥門設(shè)備的正常使用。Y 型過濾器的過濾網(wǎng)采用不銹鋼雙層網(wǎng)結(jié)構(gòu)，堅固耐用，具有結(jié)構(gòu)*、流阻小、排污方便等特點，可用于水、蒸氣、油品、硝酸、尿素、氧化性介質(zhì)等多種介質(zhì)。可根據(jù)用戶需要設(shè)置過濾網(wǎng)的目數(shù)，一般通水網(wǎng)為18-30目，通氣網(wǎng)為40-100目，通油網(wǎng)為100-480目。
