【國標鑄鋼截止閥結構特點及用途】
1.全關時手輪按順時針方向旋轉；
When fully closed,the handwheel rotates clockwise.
2.可以安裝在管道的任何位置上，介質從下往上流；
Able to be mounted on any position of the pipeline,the medium flows from down to up.
3.不銹鋼截止閥適用于各類腐蝕性介質的管道上，有良好的防腐性和足夠的強度；
Stainless steel made stop valve is of good anti-corrosive property and enough strength and suitable for various pipelines with corrosive medium.
4.合金鋼截止閥適用于耐高溫的蒸汽、油品管道上，具有耐高溫特點。
Alloy steel made stop valve features high-temperature resistance,suitable for high-temperature steam and oil goods pipelines.
