In injection molding, you need two things from a non-return valve: rapid material shut
off for part weight consistency; and a smooth, high-flow profile to prevent material degradation.

The QSO valve from Glycon gives you both. And that means higher quality parts, fewer rejects, improved yield, and a better return on every pound of material you run.
