KRACHT限壓閥SPVF 32 A1 G1 A12連接于管路中,對低壓液壓回路的壓力進行限定。廣泛地應用在鍛壓機械、工程機械、機床工業、汽車工業、冶金工業、農業機械、船舶交通、鐵道車輛和飛機、坦克、雷達等國防工業中。
KRACHT限壓閥是根據壓力系統的工作壓力(工作溫度)自動啟閉,一般安裝于封閉系統的設備或管路上保護系統安全。當設備或管道內壓力或溫度超過安全閥設定壓力時,自動開啟泄壓或降溫,保證設備和管道內介質壓力(溫度)在設定壓力(溫度)之下,保護設備和管道正常工作,防止發生意外,減少損失。 技術參數:
管連接(jie)規格:SAE法蘭3000psi 惠(hui)氏管螺紋G 安裝方(fang)向(xiang):調(diao)節螺釘垂直向(xiang)下(xia) 殼(ke)體(ti)材料:G630(GJS-400] 壓力設定方式:螺釘(ding)、旋鈕 附件:焊接式法蘭接頭(tou)SAE(3000psi 液(ye)壓油:液(ye)壓油DIN 51524/25
