15. Polyol Heater Probe
Provides information on the temperature of the Polyol.
16. Isocyanate Inlet Filter
Avoids the penetration of solid particles inside the Isocyanate pump of the unit.
17. Polyol Inlet Filter
Avoids the penetration of solid particles inside the Polyol pump of the unit.
18. Main Pneumatic Valve
It opens and closes the flow of air coming into the pneumatic system.
19. Retract Valve
Sets the piston rod of the Isocyanate proportioning pump to the retract position and prevents the
