| 本產(chǎn)品參照意大利產(chǎn)品的特點(diǎn)，與普通球閥相比，具有結(jié)構(gòu)長(zhǎng)度短、重量輕、安裝方便、節(jié)省材料等顯著的優(yōu)點(diǎn)。對(duì)夾保溫夾套球閥保溫效果好。此外，閥座采用彈性密封結(jié)構(gòu)，密封可靠，啟閉輕松。設(shè)有耐火結(jié)構(gòu)，萬(wàn)一發(fā)生火災(zāi)時(shí)，仍然能夠可靠操作并具有良好的密封性。根據(jù)用戶需要，可設(shè)有防靜電結(jié)構(gòu)。設(shè)置了90°開(kāi)關(guān)帶孔定位片，根據(jù)需要可以加鎖，防止誤操作。 |
