Author	Topic:   Ball checks
Tom Swartz Junior Member	posted 06-04-2001 11:44 AM             Why would I ever need to use a ball check non return valve? VS. a normal 3-5 piece tip assembly. IP: Logged
admin2 Junior Member	posted 06-05-2001 11:12 AM                ball checks are known for their positive shut-off (quicker/faster than check rings) and potential for material stagnation. Be cautious if considering lots of material/color changes. Not recommended for heat sensitive materials. May be a good choice for short cycle thin wall molding... IP: Logged
