Dispensing Valves - Animo OptiBean Service Book

3.7.1 Dispensing valves

The dispensing valves [2] used in the OptiBean are all the same and are so called 3-way valves.
Brewer valve DV1, mixer valve DV2 and hot water valve DV4 are used as N.C. valve (Normally
Closed). The connection P [2.1] is connected to the pressurised side. At a de-energized valve, outlet A
[2.7] is in open connection with the outlet R [2.2], so the tubes towards the mixer and hotwater outlet
always runs empty. During a drink selection one of the dispensing valves [DV] is ACTIVATED and
opens. Outlet R [2.2] closes and pressurised water flow from connection P to A.
The (expansion) dispensing valve DV6 is build-in as a N.O. valve (Normally Open). Connection A [2.7]
is connected to the pressurised side. Expansion water from the boiler can escape from connection R
[2.2]. The valve DV6 will be closed when a coffee (10 bar) is made.
