The Tilting Disc Check Valve has a net flap type closing part. The valve coil rotates around the rocker arm axis and is offset from the surface of the valve seat. When the valve flap is lowered and close to the valve seat, when the valve flap is opened, the valve flap rises from the valve seat. Since the center of gravity of the entire disc only moves between the fully open and fully closed positions, and the stroke is very short, the Tilting Disc Check Valve closes quickly.
The sealing surface of the Tilting Disc Check Valve seat is a part of the oblique cone. The sealing line formed between the valve seat and the valve disc is an approximate elliptic curve, and the angle between the curved plane and the center line of the valve flow channel is 60 degrees; the long axis center of the approximate elliptical sealing line forms an angular eccentricity with the tapered axis, namely: A second eccentric included angle of 15°～20° is formed between the axis of the cone where the sealing surface of the valve seat is located and the centerline of the flow passage of the valve body. The axis of the valve disc rotating shaft is eccentric relative to the axis of the cone, and is also relative to the axis of the cone. The eccentric position of the cone axis seals the plane of the line to form an eccentricity.

What are the advantages of Tilting Disc Check Valve?
1. Double eccentric valve disc, the valve acne and the sealing surface gradually contact when closed, so as to achieve no impact and noiseless work.
2. Micro-elastic metal valve seat, good sealing performance; cylindrical valve body design, axial flow-eliminate debris accumulation area, increase capacity.
3. Butterfly valve disc design, fast and sensitive switching, long service life; self-centering of the conical sealing surface. It is suitable for vertical pipes where the medium is from bottom to top.
4. The swash plate structure makes the flow channel streamlined, the flow resistance is small, and the energy saving effect is good.
5. It can be equipped with external manipulators, fitness poles and limit switches. Integrated lifting handle makes maintenance more convenient.
6. Replaceable valve seat ring-the material is more suitable, the surface of the valve seat is easier to repair, and the two-way seal with the elastic top valve seat is tightly closed.
7. Non-impact design, hydraulic valve disc design can realize fast operation without spring breakage.
8. The adjustable valve body can be stopped to achieve full stroke and positive closure, without causing damage to the needle of the wear-resistant material, which can be used for a long time.
9. The entire valve seat, pin and valve disc of the Tilting Disc Check Valve can be installed and tested before being welded to the valve body to eliminate seal leakage. Easy to operate and maintain online. The rotating center pin is close to the center of gravity, there is no sliding between the disc sealing cone and the valve seat, and the water hammer phenomenon is greatly reduced.
