The FQ1 series entirety structure that big prosperous Yan Cheng city petroleums and chemicals equipment Ltd. produces has gone straight to the dyadic flange ball check and products such as TQ1 series inner thread ball check , dyadic FQ3 series three direct links flange ball check , design structure new and original has overcome no nice weakness sealing off a document arousing a product from big upright difference in temperature unexpected turn of events sealing off effect, under using product working condition condition changing in 100 ∽+ 540 difference in temperature martyrs-, the function keeps hermetic sealing all the time invariable, fire prevention, guards against static electricity. That standard mass classifies reaches a top-quality goods , is oil equally, coal gas and deleterious harmful gas, liquid loses transporting pipeline equipment supporting the best choice.
