. The pneumatic membrane cuts off the valve Valve body hydrodynamics it go through originally Hui counting as section not low to it is if hindering , line will be flowed to flow of, ladle out there aren't flow the coefficients.
. In valve piece sealed part type not tight without being had and gill Yue seal two kinds of,type not tight , for piling not welding there aren't quality not hard
. One, has improved in the balancing type valve Cut off the valve Noisy Juan pigeonhole explain sword
. Corrugated pipe sealed type form to valve stem that move E take Qian stop up possibility that the medium leaked definitely.
. Lopsided swilling type executive body, operate strength E and use and press to explain the domestic animal.
