Operating Procedures:
NOTE: Limit air pressure to 6bar (90psi) or the PPVS can be damaged.
NOTE: Apply release agent to the internal 10mm bore of the valve (inside the
nose) when the valve is actuated in the inject position (shaft up-most) to prevent
the seal sticking up.
Operating Procedures using PPVS and IVX3:
1. Put the IVX3 Valve in the Off mode (CLOSED).
2. Set MPG pressure and pump pressure.
Caution: Do not exceed the Pressure Rating of the injection hose for the MPG or
Pump pressure note the ratio of the pump powerhead to fluid section in this
calculation.
3. Put the IVX3 Valve in Purge mode (PURGE)
4. Start machine and wait for the resin to start to flow into the supply line, prime valve,
resin flows into flush line.
5. Now put the IVX3 Valve in the Off mode (CLOSED). Reset the counter before
injecting into the mould for an accurate count.
6. When you are ready to Inject put the IVX3 Valve in Inject mode (Inject position).
PPVS should open and close the IVX3 valve automatically and when the valve is
closed the machine (Innovator) should stop on the MPG.
7. When the mould is full, put the IVX3 Valve in the Off mode (CLOSED) and stop the
machine.
8. Put the IVX3 Valve in Purge mode (PURGE) and then flush. Leave the IVX3 Valve
in the Purge mode (PURGE) unit the material is gelled.
NOTE: Leave IVX3 valve in purge mode (with air on the actuator) while the resin
cures, this stops resin curing in the valve.
