Use for Intended Purpose

Use for Intended Purpose
To protect the metering line from impermissible overpressure
caused by the metering pump when a stop cock valve is
connected in the metering line.
• The multi-function valve may not be used to protect the
discharge line from inadmissible excess pressure caused by
anything other than the pressure generated by the metering
pump.
• The valve must not be used as a shut-off.

Mounting / Installation

Safety Requirements, Notes on Safety
IMPORTANT
• Pressurised systems must have a non-return valve fitted at
the metering point because the entire contents of the
system can flow back via the bypass when the valve is
operated.
• The bypass line must always be connected since minimum
overflow into the bypass line can occur during operation of
the valve close to the pressure relief function.
• Multi-function valves are not intended to act as fully sealing
stop taps!
Mounting Description, Mechanical/Hydraulic
The multi-function valve is screwed directly on to the pressure
connection of the pump. The valve can be turned and aligned
through 360°.
The metering line or metering hose is secured on the outlet end by
means of a connection set or GF screw fitting. An EPDM O-ring is
fitted at the factory in the O-ring groove at the outlet. For applica-
tions in which EPDM is not suitable, it is advisable to fit a Viton B
O-ring. This O-ring (brown) is supplied together with the valve.
The bypass line is routed into the supply vessel. It is secured by
means of a hose grommet and union nut.
