For this Phase
If Using Only this Control Then Skip the Section(s) Titled:
clamp close velocity FCC, SCC, TCC Profiles - Pressure Valves
pressure: and your valve
configuration is the same for all
four profiles FCC, SCC, TCC, LPC
LPC Profile - Low Pressure Valve
and
FCC, SCC, TCC Profiles - Velocity Valve
injection velocity INC Profile - Pressure Valve
pressure INC Profile - Velocity Valve
clamp open velocity FOC, SOC, TOC, OSC Profiles - Pressure Valve
pressure FOC, SOC, TOC, OSC Profiles - Velocity Valve
ejection velocity EAC, ERC Profiles - Pressure Valves
pressure EAC, ERC Profiles - Velocity Valves
For each of the available profiles, decide which ones you will:
span for pressure control
span for velocity control
operate in closed loop
operate in open loop
not use
To assist you, we provide worksheet 9.A. Use it to select only the valve-
spanning procedures required for your particular application.
