Series 550 LP and 560 HP Manual Dispense Valve 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 flow.)
