Trunnion ball valve elastic ball valve

The ball valve is elastic. Ball and seat ring are made ??of metal materials, sealing pressure than large, rely on the media itself has reached less pressure sealing requirements must apply force. This valve is suitable for high temperature and pressure medium. Elastic sphere is the sphere in the lower end of the inner wall of the opening of a resilient groove, Instrument valve and access flexibility. When closing the channel, wedge-shaped head with a stem so that the ball up on and the valve seat seal. Before turning the ball first release wedge-shaped head, the ball followed by restoration of the original prototype, so there is very small gap sealing surface can reduce friction and operating torque between the ball and the valve seat. Ball position can be divided according to their straight-channel, three-way and the right angle. After two ball valves for dispensing media and change the flow of the medium. Ball O-Ball and V-ball points. O type ball floating structure, ball core for precision castings, hard chrome plated exterior,Double ended cylinder seat with PTFE material, the same stream crossings and pipe diameter, maximum flow capacity, flow resistance is extremely small, closed without leakage, generally do switch valve, especially suitable for high viscosity, fibrous, granular media; V-ball with a fixed structure, opened a V-notch ball core, can achieve proportional control, flow characteristics such as the approximate percentage. Depending on the choice of process equipment pneumatic or electric actuators, pneumatic valve and were composed of electric valve, which pneumatic valve as required to achieve the proportional control valve with positioner, electric valve as required to achieve the selected electronic proportional control electric actuator or with servo amplifiers.
