    Many people might take it for granted that when they turn on their water everything will flow normally. But some homes might be missing an important piece of equipment you may never have heard of -- pressure regulating valve.   Margaret Cantrell learned the hard way. She has an expensive ...

  • Feature of Hard Seal Eccentric Semi-Ball Valve
    Posted: 09/23/2016 16:07:21 Hits: 5

    Hard seal eccentric semi-ball valve uses the common path of eccentric body, eccentric ball, seat and stem for centring when they make rotational motion. It is tighter during closing to realize sealing. The ball is separated from seat completely, eliminating the abrasion of sealing ring and overcom...
