Pinch valves
Pinch valves are used to control the path of the
liquid flow through the system. There are 19 pinch
valves in total. The valves have manually operated
safety locks keeping the tubing in place and pre-
venting the valves from accidentally closing during
flow kit installation.
WARNING
Never put fingers or any objects other than the intended tubing in
to the pinch valve opening.
