V-ball (pneumatic control) is a quarter-turn structure V-ball offer, it positioner supporting the use of proportional control can be achieved; V-type valve (pneumatic control) valve is ideal for a variety of regulatory situations, with a rated flow coefficient, adjustable V-ball ratio, good sealing effect, adjust the performance of zero-sensitive V-ball manufacturers, small V-ball suppliers, can be installed vertical lying. Suitable for controlling gases, vapors, liquids and other media. v type ball valve (V-type valve) is the flow control system is very important part, in some harsh environments, the internal valve will cause some wear and tear, then this is how the wear caused it? Generally there are four kinds of such cases are caused by forms. 1. Adjust the valve itself, wear particles, v-type regulating valve in the course of the work will produce friction between particles; 2. cavitation valve is generally used for a long time will have this phenomenon; 3. oxidation corrosion products; 4. When fluid at high speed, the friction generated between the medium in the valve. V-ball manufacturers | V-type valve | valve V-ball Everbright Ltd. Shandong Everbright provided by the valve.
