Floating Ball Valve Side Entry Split Body - High Temperature



Heating to boiling points, catalytic and hydro-treatments are some of the refining processes necessary to separate crude oil into storable fractions like marketable oils and condensate; most of these processes take part at high temperatures. ERREESSE production range offers valves engineered to withstand and exceed high temperature applications with specific constructions and duly selected materials.


  • Low Alloy Steel
  • Stainless steel
  • Other materials can be used upon request



Construction Two or Three piece bolted body
Port Reduced bore, full bore or fully piggable
Stem retention Anti blow-out stem
Leakage rate ISO 5208 rate A, B, C or D during hydrostatic test
Antistatic device Included, the ball valve design includes an electric conductive connection between the internal parts of the ball valve and the body, providing the anti-static function.
Pressure relief Automatic cavity relief to prevent overpressure in body cavity(self-relieving seats)
Sealing Bi-directional, Double block & bleed (DBB) with sealing in both directions (DIB-1&2 upon request)
Metal seated with Chrome Carbide Coating and Stellite coating depending on the application and temperature range
Metal seat sealing with differential hardness between ball and seat to prevent galling of the substrate
Metal sealing by means of graphite packings on all valve seal areas
Drain Drilled and threaded connections for all sizes
Vent Drilled and threaded vent connections for sizes ≥ DN150 (6") < DN150 upon request
Grease injectors Available on request for both seats and stem
Lifting points Included for sizes ≥ DN150 (6") or on valves of 250 kg min
Support feet Included for sizes ≥ DN150 (6") or on valves of 250 kg min
Stem extension High Temperature stem extension as standard to allow for thermal dissipation of excess temperature and allow for the seals to work properly at a lower temperature than that of the process fluid in bore
Valve operation Lever, Gear box or Actuator with position indicator andlocking device
