Metal Seated Flanged ball Valve









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.

The SANKEY TBV series flush bottom tank ball valve incorporates all the benefits of ball valve negating the disadvantages of conventional flush tank valve. Our Sankey TBV series valve incorporates the geometric design of the mounting Pad, which is welded to the tank, allowing a smooth flow and prevent stagnating of the media.
Our Valves offer the best solution:

  • Where minimum Dead Space between ball and tank is required.
  • Where media could stagnate at tank outlet.
  • Where Full blending of reactor volume is imperative.

Advantage over a conventional tank bottom valve



  • Higher CV
  • Direct Flow
  • Simple Quarter turn operation (Easy automation)
  • Low weight and compact
  • Easy maintenance

Valve Application: Filter dryer / vacuum dryer / Stirrer vessel / Transport vessels / Reactor / Other vessel
Areas of application: Chemical / Pharmaceutical / Food / Cosmetics
Media: Gases / Fluids / Emulsion / Syrup / Paint / Food Product (Chocolate etc.) / Granulate material / Powder.

KEY FEATURES:

ADVANTAGES
SANKEY Tank Bottom Ball Valve

Low sump area
By the use of an angled stem design and the direct mounting to the vessel bottom flange, the ATEC bottom outlet ball valve ensures flush fitting with the vessel inner bottom.

  • Minimal accumulation of product between ball valve ball and vessel inner bottom
  • Improvement of product mixing in stirrer vessel
  • Reduction of efflorescence and product agglomeration
  • Avoiding false samples

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

Angled stem design
Because of the further distance from the actuator mounting flange to the vessel, it makes the automation of the ball valve and isolation of the vessel very convenient.

Direct mounting to vessel flange
The ball valve is mounted directly using screws or bolts to the vessel flange.

• Direct and easy assembly of ball valve to the container flange
