Use: apply double seal valve guide: aviation kerosene, crude oil, light oil, natural gas, LPG, gas pipelines, chemical piping and other medium, as a cutoff means over the medium. Characteristics: ①during switching valve, slide valve sealing surface and the sealing surface without any contact, and therefore, long life sealing surface without friction, wear, valves, small torque switch; ② valve repair, without the remove the valve from the pipeline, the bottom cover only the valve open, one pair of slide can be exchanged, maintenance is very convenient; ③ valve plug and full bore, no medium flow resistance through the valve, and may pass balls of pipe cleaning, overcomes the disadvantages of the reduced diameter valve; ④ body cavity is plated with hard chromium, hard and smooth sealing region; ⑤ slide on the elastic seal fluorine rubber, and the molding surface of the slide groove. ⑥ valve with automatic bleed device (optional), after the valve is completely closed, to prevent the valve chamber abnormal pressure and check the valve effect; ⑦ valve switch instructions Device and switch position synchronization, can accurately display the valve switch state.
