Condition type
Description
Fluid phase
Liquid
Process temperature
-29 °C to 66 °C (-20 °F to 150 °F)
Fluid velocity
Operational recommended flow velocity up to 30 ft/sec,
beyond this point will result in a high pressure drop and
increased wear.
Fluid(s) controlled
•
Low/Medium viscosity crude oils and condensates
•
Refined products and intermediates (ie: gasoline, diesel,
kerosene, light fuel oils, jet fuel, LPG, butanes, naphtha,
alkylate, reformate, straight run gasoline, cat-cracked
gasoline)
•
Petrochemicals (ie: benzene, toluene, xylenes, cumene,
olefins, pyrolysis gasoline)
•
Natural gas liquids
Viscosity limits
Maximum valve viscosity is 8800 Cst
Differential pressure
The maximum allowable differential pressure across a control
valve is 6894 kPa (1,000 psi). Consult factory for location of
first shut down valve.
Sizes (NPS)
