Accumulator discharge valves series TEA are preferably
used in hydraulic systems where high flow rates are
discharged from hydraulic accumulators over a short
operating period (in the range of milliseconds). Typical ap-
plications are injection molding and die casting machines
as well as hydraulic presses.
Basically the function of an accumulator discharge valve
corresponds to the function of a TDA throttle valve. In ad-
dition a directional valve is integrated in the pilot circuit
to meet the relevant safety regulations.
The directional valve provides the safety function. When
the solenoid is deenergized and the spring is in end posi-
tion, pilot pressure from X presses the control piston into
lower end position and the main poppet is closed. As a
result the flow from B to A or from the reservoir system
to the machine is blocked.
