XCHANGE™ Utility Module
Heavy Duty Fluid/Coolant Modules
These Modules pass fluid during an automatic tool changing operation.
Advantages
• Flexible Connection Options
• Valved/Checked interface on both Robot and Tool Adaptors
• Clear indication of supply/return lines
o AIR, WATER IN, WATER OUT
• Coolant Modules have Extended Fittings to seal connection prior to flow of coolant
FLOW FORMULAS
Imperial measurement units:
Flow of Gases (Pneumatic Module) Flow of Fluids (Coolant Module)
QG = Gas flow rate in Standard Cubic Feet per Hour (SCFH)
Q = Valve flow rate in gallons per minute (US gpm)
Cv = Flow Coefficient = 1.54 for these modules
P1 = Upstream (inlet) absolute pressure in pounds per square inch (psi)
P2 = Downstream (outlet) absolute pressure in pounds per square inch (psi)
GG = Specific gravity of medium where air at 70°F and 14.7 psia equals 1.0
GF = Specific gravity of fluid related to water
T = Absolute temperature in °R (°F + 460)
Metric measurement units:
Flow of Gases (Pneumatic Module) Flow of Fluids (Coolant Module)
QG = Gas flow rate in Standard Cubic Meters per Hour (m3/h)
Q = Valve flow rate in Cubic Meters per Hour (m3/h)
Cv = Flow Coefficient = 1.54 for these modules
P1 = Upstream (inlet) absolute pressure in bar
P2 = Downstream (outlet) absolute pressure in bar
GG = Specific gravity of medium where air at 20°C and 1 bar equals 1.0
GF = Specific gravity of fluid related to water
T = Absolute temperature in °R (°F + 460)
