撞擊式帶軸承大口徑截止閥概述：
撞擊式(帶軸承)大口徑截止閥結構先進、密封可靠、性能優良、造型美觀。特別是啟閉采用了活絡連接結構，極大提高閥桿的鋼度，顯著降低了噪音和振動，提高了閥門的使用壽命與各項性能�？梢园惭b管道的任何位置上，介質可在任意方向通過。
1.DN250以上采用先進的多密封，雙支架，采用導向運動（能極大提高抗水錘沖擊）、介質從上方進入，交好解決了大口徑截止閥啟閉力距大，密封無法關嚴，填料室跑冒、漏等問題，有力提高了閥門各項性能與使用范圍。（“關”的力矩是普通閥門的10%“開”的力矩是普通閥門的3%）。
2.不銹鋼截止閥適用于各類腐蝕性介質的管道上，有良好的防腐蝕性和足夠的強度。
3.合金鋼截止閥適用于耐高溫耐的蒸氣、油品管道上，具有耐高溫特點廣泛應用于給排水、冶金、蒸汽、電力、石油化工等行業，是現代工業中理想的通用管道控制部件。
