Wear-Resistant Ball Valve For Catalyst

The wear-resistant ball valve for catalyst is aspecial valve designed for the catalyst process pipeline. The surface of thewear-resistant valve core of the wear-resistant ball valve is sprayed with ahigh-speed coating of tungsten carbide by a supersonic flame spraying process,and the valve seat sealing layer is too hard. The alloy is effective againstthe scouring and wear of the granular catalyst and prolongs the service life ofthe valve. The wear-resistant ball valve stem of the catalyst is made ofhigh-strength stainless steel. The larger stem diameter improves the rigidityof the connection with the valve core, ensuring reliable and safe operation ofthe valve.

Product Features

Valve stem: anti-flying valve stem design, effectively avoiding the valvestuck in long-term high temperature conditions and possible site safetyhazards. Super heat-resistant stainless steel + hardened to increase thetolerable torque.

Gasket: Type 304 +flexible graphite wound gasket, fire safety in accordance with API607

Pivot: The upper and lower shafts are supported and positioned. Under theaction of medium pressure, the ball has no movement of the valve body in theaxial direction, and the structure is simple and the reliability is strong.

Spring: The live-filled packing seal design ensures long-term reliabilityof the stem seal

Packing: stainlesssteel wire is combined with flexible graphite braided filler + flexiblegraphite ring. The braided packing ensures tight connection between the stemand the stuffing box, preventing the filler from being squeezed and keeping thestem aligned, which provides a reliable seal and longer use life.

1. Inconel metalspring, which effectively compensates for the wear of the sealing surfacecaused by long-term high temperature use. The double spring dust-proof designovercomes the risk of the medium blocking the spring and eventually causing thespring to fail. 2. Seat scraper self-cleaning design, a variety of hardenedcoatings on the sealing surface can be selected HRC≥65, strip seal to achievezero leakage.
