Strucure features and usages:
全關(guān)時(shí)手輪按順時(shí)針?lè)较蛐D(zhuǎn);
可以安裝在管道的任何位置上,介質(zhì)從下往上流;
不銹鋼截止閥適用于各類(lèi)腐蝕性介質(zhì)的管道上,有良好的防腐性和足夠的強(qiáng)度;
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(diǎn)。
When fully closed,the handwheel rotates clockwise.
Able to be mounted on any position of the pipeline,the medium flows from down to up.
Stainless steel made stop valve is of good anti-corrosive property and enough strength and suitable for various pipelines with corrosive medium.
Alloy steel made stop valve features high-temperature resistance,suitable for high-temperature steam and oil goods pipelines.
