Description
Liquid
-20° F to 150° F (-29° C to 66° C)
-50° F to 400° F (-46° C to 205° C )
Operational recommended flow velocity up to 30 ft/sec, beyond this
point will result in a high pressure drop and increased wear.
•
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
•
Maximum valve viscosity is 8800 Cst
•
Maximum viscosity for valves with pilots is 440 Cst due to
response time of high viscosity pilot
The maximum allowable differential pressure across a control valve is
6894 kPa (1,000 psi). Consult factory for location of first shut down
valve.
Absolute
2, 3, 4, 6, 8,10,12,16
150, 300, 600
•
15° F to 400° F (-26° C to 204° C)
•
Using FKM O-rings
•
Temperature range is dependent of O-ring T
•
Max temperature of valves with solenoid pilots is standard -20° F
to 150° F (-29° C to 66° C) (if applicable), Optional 250° F (121° C)
•
Consult the factory for other safe working temperatures
