Feature:
⊙ Resist friction
Valve disc is given enough intensity and rigidity. Disc sealing surface may be built-up
welded with satellite alloy inlaid or other material responding to the users’ request.
⊙ Agility of switch
Solid ping is precisely installed and provided with high intensity to ensure operational performance
and service life of valve.
⊙ Sealing credibility
The check valve adopt swing configuration. All the sealing part inside the valve, so all exterior leak
may except the middle flange, and also the middle flange gasket may be different according
to pressure class.
⊙ Distortion compensating
The disc and the hinge are connected between slippery spherical surface, and this makes the disc
can circumgyrate in a little angle and regulates the sealing capability.
