working principle:

The anti-wear ball valve adopts special profiling ball and double eccentric design, with double vector movement, so that the valve seat and profiling ball will not contact, friction or wear during the valve opening and closing process. When closing, the mechanical seal is ensured through cam effect to achieve zero leakage of metal seal, and the sealing performance is one order of magnitude higher than the current industry standard (BS6364). The sealing power acts on the fixed valve seat through the valve stem, without lip seal and spring auxiliary seal, and without dynamic seal, excellent, reliable and consistent sealing performance can be obtained under high and low pressure conditions. Fire protection design.

In severe conditions, this sealing design ensures that the medium will not accumulate and harden between the valve seat and valve body, thus preventing valve failure. The profiling ball design has no dead zone in the valve chamber of traditional valves, eliminating the risk of catastrophic failure caused by the expansion of unstable medium in the valve chamber in the two-way sealing design.

Main applications:

Bulk material application: long conveying pipeline, powder pneumatic conveying, powder dense phase conveying, lithium powder dense phase conveying, photovoltaic powder particle dense phase conveying, steel plant fly ash conveying, negative material dense phase conveying

Medium applications: LNG liquefaction station, LNG regasification station, peak shaving plant, LNG bunker, floating storage gasification unit (FSRU), LNG filling station, LNG ship, gas fractionation plant, ethylene storage tank, ethylene storage tank, rocket engine test, air separation unit, emergency shutdown, etc

Product features:

1. Fault free operation The valve cavity free design eliminates the opportunity for products to accumulate and harden in the cavity and endanger valve operation, and you will enjoy a long period of stable operation. High performance hemispherical valve/anti-wear hemispherical valve can also ensure the safety of volatile fluid that is easy to expand, decompose or ignite in the valve chamber.

2. Reduce particle wear In the application of harsh working conditions, achieve a longer tight shutdown, low friction of cam movement, thus reducing the wear caused by particles. In contrast, traditional ball valves with concentric movement are very vulnerable to seal wear.

3. insurmountable protection In the application of abrasive particles, the structure of the profiling ball allows HVOF coating to cover the internal and external full surfaces. The hard coating on the inner and outer surfaces has no seam, which is extremely abrasion resistant and erosion resistant.

4. Smooth rotation performance pays attention to small details. Two piece shaft sleeve is used to create an improved low friction surface and improve cycle life.

5. Optimized fixed seat design for sealing high-performance hemisphere valve, providing repeatable tight shutoff; The use of spring is removed; It also avoids the scaling, valve seat pollution and premature valve failure caused by the accumulation of media in the valve seat area.

6. Particle sweeping adopts convex to convex valve seat structure to reduce the closing force of the valve. This structure can sweep particles during 2-3 degrees of movement before closing, instead of squeezing particles into the valve internals, so as to maintain the integrity of the seal.

7. The integrity of the fixing ball can maintain the integrity of the packing and ensure long-term reliability through optimized sealing. These seals can prevent materials from entering the top and bottom areas of the gauge ball, and will not cause wear to metal parts.

8. The excellent structure and thick upper and lower fixed shafts are integrated with the profiling ball to support the ball to absorb the process load, and protect the valve rod from side load to reduce the wear of mechanical parts, so as to ensure the integrity of the packing in high-frequency applications.
