W43, release valve in the deionized water circuit

Availability of option
This option is available for the following S120 Cabinet Modules:
● Heat Exchanger Modules
Description
A release valve is installed between the intake and return in the converter-side deionized
water circuit.
The valve limits the pressure of the circulating pumps. It ensures a minimum flow rate by
opening as soon as the pressure exceeds the value set at the valve.
Note
The pressure is only regulated by the release valve
Adjust the "ball valve to reduce the pressure at the intake of the converter-side deionized
water circuit" (77.3) to "open" in order for the release valve to be able to regulate the
pressure.
