1) using the most advanced bi-directional design of the world at the present.
2) Flexible and airproof structure for board of valve.
3) Mirror process for board of valve, base of valve, airproof antrum, pole of valve.
4) Airproof antrum use short and narrow design. It makes the airproof efficiency tiptop.
5) Airproof use “the sandwich” structure. R-PTFE ripple airproof keep the strictness and airproof longinquity.
6) Using 4000psi pressure for airproof structure, in order to unsure well-proportioned pressure and nil leak.
Our middle press high-powered butterfly valve, with novel structure, much more service and rationalization, together with automatic installation flat roof, compression resistance and airproof capability are better than the congener. The positive compression resistance is 75kgs/cm2, the negative compression resistance is 20kgs/cm2, heat-resistance can reach 240C。Our design patents are applied extensively in many countries, such as system, regeneration system.
Doffing sulphur system(FGD): butterfly valve with alloy board, china ball valve, septum valve and heavy caliber butterfly valve(FGD system, the most heavy calibre, butterfly valve is DN1300, HA’s alloy is C, which applied for H+C), anticorrosive and wearable valve etc.
The major medium is plaster serum for these system, which is demanded the valve, with antisepsis and antifriction. Especial, the components which contact serum medium should be applicable it entirely. H&G valve company ever cooperated with WuHan Kaidi Electric system china area in 2001. We have matched great of inland FGD project. And till now, the outstanding achievement and
