Safety Valve
Activate the safety valve piston. This prevents the material from blocking the
safety valve.
Procedure:
1. Relieve pressure as described in section Installation.
2. Disconnect all hoses.
3. Close hose connections with Nordson port plugs (Fig. 5-15).
Fig. 5-15
4. Pressure Control Valve: Measure and make a note of the insertion
depth (Fig. 5-16: dimension X) of the setting screw (2). This ensures that
the insertion depth can be reproduced. Close the pressure control valve
by turning it all the way clockwise.
5. Operate the melter at full motor speed and with hose connections
closed. Switch the motor on and off several times.

CAUTION: For safety reasons, the safety valve may not be disassembled.
The complete valve must be replaced every time. Refer to section Repair.
Nordson recommends keeping a supply of replacement safety valves.
There is a spare parts kit available for the outer O-rings.
