The inexpensive Series 550 LP (shown at right) and
560 HP Valves are intended for low pressure and
high pressure meter mix applications, respectively.
These manual valves are ideal for dispensing beads
or RTM casting. The design is simple: two ball
valves are threaded into the back of the manifold
and are connected to a common lever so that both
valves open and close at the same time.

(The 550 LP Valve is not intended for “feathering”
or otherwise attempting to meter the ow.)
