Series 550 LP and 560 HP Manual Dispense Valves

The inexpensive series 550 low pressure valve is intended for low pressure meter mix applications. This manual valve is ideal for dispensing beads or RTM casting. The design of the 550 LP dispense valve 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 simultaneously. The 550 LP valve is not intended for this "feathering" or otherwise attempting to meter the flow.
