?Liner Sealing face – to get lower operate torque.
Most factories’ design is the same lever sealing face.
while when the valve closed, the increasing inlet pressure will push the disc shift and press the valve body, which will cut the disc rubber of position “A” during long term use.
IVALVE has been aware of this defect and improve the design to avoid the hurt mentioned above,and by the new design,thedisc service life has been extended.
