API Titling Disc Check Valve Casting Steel 150LB

Titling Disc Check Valve has a mesh closure. The valve disc rotates about the rocker arm axis and is offset from the seat surface. When the disc is lowered and close to the seat, the disc lifts from the seat as it opens. Since the center of gravity of the entire disc only moves between the fully open and fully closed positions, the stroke is very short, so the swash plate check valve closes quickly.

The sealing surface of the valve seat of this product is a part of the inclined cone. The sealing line formed between the valve seat and the valve disc is an approximate elliptic curve, and the included angle between the curve plane and the center line of the valve flow channel is 60 degrees; an angular eccentricity is formed between the long axis center of the approximate elliptical sealing line and the cone axis, namely: , a second eccentric angle is formed between the axis of the cone where the sealing surface of the valve seat is located and the center line of the flow channel of the valve body, which is 15° to 20°. At the eccentric position of the cone axis, the plane of the sealing line is eccentric.
What are the advantages and characteristics of the Titling Disc Check Valve?
1. Double eccentric valve disc, when closed, the valve acne and the sealing surface are gradually contacted, so as to achieve no impact and noiseless operation.
2. Micro-elastic metal valve seat, good sealing performance; cylindrical valve body design, axial flow - eliminating debris accumulation area and increasing capacity.
3. Butterfly Valve disc design, fast and sensitive switch, long service life; tapered sealing surface self-centering. Suitable for vertical pipes where the medium is bottom-up.
4. The swash plate structure makes the flow channel streamlined, the flow resistance is small, and the energy saving effect is good.
5. Can be equipped with external operators, fitness bars and limit switches. Integrated lift handle, more convenient maintenance.
6. Replaceable seat ring - the material is more suitable, the seat surface is easier to repair, and the two-way seal with the elastic top seat closes tightly.
7. Non-impact design - The hydraulic valve disc design enables quick operation without spring breakage.
8. The adjustable valve body can be stopped to achieve full stroke and positive closure without causing damage to the anti-wear material. The hinge pin can be used for a long time.
9. The entire seat, pin and disc of the swash plate 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 rotation 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.
