IVx3 Injection Valve Manual

Operating Procedures:
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:
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).
The PPVS should open and close the IVX3 valve automatically and when the
valve is closed the machine 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.
NOTE: If the valve seal sticks in the purge position after an injection, just supply
air to the inject position airline to driver the actuator upwards. Then operate the
valve between purge and inject positions a number of times and ensure inside of
nose is clean and the valve moves freely.
