高中壓法蘭連接的閘閥適用于公稱壓力PN1.6～16.0MPa,工作溫度≤-29℃～550℃的石油、化工、水力、火力電站各種系統的管路上，切斷或接通管路介質。適用介質為：水、油品、蒸氣、及酸、堿、氨、尿素、含硫天然氣等。
結構特點
1、選材考究，符合國內外相關標準，材料的全面質量高。
2、符合標準的要求，密封可靠、性能優良、造型美觀。
3、密封副配對合理，閘板和閥座的密封面采用不同硬度的司太立（Stellite）鈷基硬質合金堆焊而成，密封可靠、硬度高、耐磨、耐高溫、耐腐蝕、抗擦傷性能好、壽命長。
4、閥桿經調質及表面氮化處理，有良好的抗腐蝕性、抗擦傷性和耐磨性。
5、采用楔式彈性閘板結構，中大口徑設置推力軸承，磨擦力小，并配有撞擊手動，啟閉輕松自如。
6、可采用各種配管法蘭標準及法蘭密封面形式，滿足各種工程需要及用戶要求。
