As a general concept, PVC true union ball valves are actually used to control the flow of water switch, manually to achieve the goal of controlling the flow. Most valve manufacturers have a variety of materials to choose from, and the advantage of plastic is moisture-proof does not rust, PVC true union ball valves why alive? In fact, in order to be able to later on the valve removal, convenient replacement.
PVC true union ball valves have spheres that are fixed and do not move when pressed. Fixed ball valve with a floating seat, by the media pressure, the seat has moved, so that the seal ring pressed on the ball, to ensure the seal. Usually with the ball on the upper and lower shaft equipped with bearings, operating torque small, suitable for high-pressure and large diameter valves. It is also widely used in petroleum refining, long-distance pipeline, chemical industry, paper-making, pharmacy, Water Conservancy, electric power, municipal, steel, and other industries, PVC true union ball valves require only a 90-degree rotation and a small torque to close tight, the most suitable for use as a switch, cut-off valve. Because PVC true union ball valves are sealed with manual grinding, until the spool and seal ring fully match can be used. So PVC true union ball valves are reliable seals. PVC true union ball valves use a spring at the bottom of the seal ring to make the seal ring and the valve core tightly together, so the switch is very light when the external force exceeds the spring pre-tightening force.
