ADVANTAGES
SANKEY METAL SEATED BALL VALVE
Metal to Metal Seating
The ball and the seat rings are hard-faced on the sealing areas by using different coatings selected upon the service conditions i.e. Electro-less Nickel Plating, Stellite hard facing, Chromium Carbide and above all Tungsten Carbide which assures, per our experience, the best results in most applications. The sealing is assured by true metal to metal contact between the two hard-coated surface. Each coating is applied per specific methodologies, i.e. Tungsten Carbide is applied by high velocity detonation gun.
Stem Design
The stem is independent from the ball and is a blowout proof design. The stem seals are designed per the service conditions, i.e. for high temperature valves (above 250 degC) stem seals is composed of loaded graphite packing. Valves for high temperature conditions are designed with extended stem to maintain the maximum sealing capacity of the packing.

SANKEY designs and manufactures metal seated ball valves with high strength stainless metal seats and balls over-layed with carbides. Metal seated ball valves are required for many extreme service conditions involving abrasives, corrosives, high cycle rates or extreme temperature and pressure. These conditions require simple, well-built but rugged designs, metal seats, rigorous testing and carefully chosen materials. Valves should be tested to nationally recognized standards and, then again, with in-house methods designed to simulate the actual process conditions.
New developments in technology and our experience addressing severe service conditions have helped us to develop several lines of new products.

Valve Application: Hot hydrocarbons / scaling carbonates / fractionator bottoms /power applications / steam / catalyst withdrawal / fly ash / corrosive slurries / acidic slurries.

Areas of application: Chemical / Pharmaceutical / Food / Pharmaceutical / Petrochemical / Energy / Plastics / Oil and Gas / Cement and lubrication

Media: Bitumen Application / Fluids / Emulsion/ Syrup / Paint / Food Product (Chocolate etc.) / Granulate material / Molten Sulphur

ADVANTAGES
SANKEY Jacketed Ball Valve

Cavity free
The usual cavity between ball and housing in non- cavity free ball valves give cause for disturbance because residual products can crystallize, polymerize and so affect the function.
  • Clean, non- false product
  • No sediments of expensive products in the ball valve housing

Fire-safe tested and approved SANKEY Wafer ball valves of the WF series have been tested successfully per British Standard BS 6755 and API-607.The material utilized for the soft seals in "fire-safe" valves remains dependent upon the required chemical resistance to suit the fluid, the application and operation conditions. When fire does break out, it is important that it does not spread through failures in pipe-work systems. Even under the most extreme conditions shut-off valves provide:

• Secure Operation, • Reliable Sealing in shut-off position, • Reliable Sealing to the outside.
