P&ID CRF62
The intended use of the Pressure regulator CRF62 is pressure relief of a gas from an inlet pres-
sure to a fixed or adjustable outlet pressure.
Pressure reduction is performed by the pressure regulator. It is equipped with one pressure
gauge to display the inlet pressure and the outlet pressure. The outlet pressure is set to the de-
sired value by turning the of the handwheel on the pressure regulator and is not permitted to ex-
ceed a defined maximum value given on the label.
The Pressure regulator CRF62 are optionally equipped with a control valve in the output. This
makes it possible to regulate the flow rate.
In the case of the double-stage pressure regulation present here, the set outlet pressure re-
mains virtually constant as the inlet pressure changes.
4.3 Technical data
NOTICE
The technical data can be taken from the data sheet for the relevant product. If this is not avail-
able, you can view and download it at
The maximum input and output pressures and the gas type are given on the identification or la-
bel.
4.4 Boundaries and interfaces
The scope of supply includes the product as described in the "Design" chapter. The transfer
points to process gas, exhaust air and auxiliary media (incl. power supply) are the connections
on the pressure control panel or product.
The following areas and functions have not been included in the scope of supply from Spectron:
– other systems, lines and installations of the overall system
– Process gas source
