1、產(chǎn)品按國(guó)家標(biāo)準(zhǔn)GBl2236設(shè)計(jì)制造,結(jié)構(gòu)合理,密封可靠,性能優(yōu)良。
2、閥瓣、閥座密封面采用鐵基合金或司太立(stellite)鈷基硬質(zhì)合金堆焊而成,耐磨、耐高溫、 耐腐蝕、抗擦傷性能好、使用壽命長(zhǎng)。
3、可采用各種配管法蘭標(biāo)準(zhǔn)及法蘭密封面型式,滿足各種工程需要及用戶要求。
4、閥體材料品種齊全,填料、墊片可根據(jù)實(shí)際工況或用戶要求合理選配,能適用于各種壓力、溫度及介質(zhì)工況。
5、閥瓣轉(zhuǎn)繞閥座外的銷軸旋轉(zhuǎn),減少關(guān)閉時(shí)發(fā)生猛烈沖擊。
6、銷軸與閥瓣連接采用內(nèi)裝式結(jié)構(gòu),不存在外泄漏點(diǎn),使用更可靠。
