A, product features: BQ41 flange floating soft (hard) insulation sealing ball valve with elastic sealing ring or V single bevel groove structure design of elastic sealing ring, when the medium pressure is small, the contact surface of the sealing ring and the small ball, it is larger than the pressure seal, ensure reliable sealing, pressure trap medium,. The sealing ring and the ball contact area, the sealing ring can withstand greater thrust medium without damage. Because the PTFE sealing ring material has good self lubrication, and the friction loss of the ball is small, so the service life of the ball increases.
