Frequently asked questions

Common questions about PLAST-O-MATIC Check Valve from 3G Electric.

How do I choose between a poppet and an inline diaphragm PLAST-O-MATIC check valve?

Poppet designs suit clean liquids and give quick, positive shutoff with low cracking pressure. Inline diaphragm models handle slurries, crystallising or particle-laden media where a poppet could foul. Match the choice to your fluid, then confirm body material, size and end connections.

Which PLAST-O-MATIC check valve material suits my chemical service?

PVC is the common choice for acids, bases and general water treatment at moderate temperatures. Polypropylene offers broader chemical resistance and higher temperature capability. Always verify the wetted materials against your specific media concentration and operating temperature before specifying.

Can 3G Electric supply PLAST-O-MATIC check valves worldwide, and what is the lead time?

Yes. We source and ship PLAST-O-MATIC check valves worldwide, with 16 catalogued items across PVC and polypropylene poppet and inline diaphragm types. Lead time depends on model and quantity; send your part numbers or line conditions and we will confirm availability and delivery.
