Plastics industry FAQs
You asked, we answered these common questions related to the plastics processing industry and rotary valves.
See all FAQs-
A.
Rotary valves can help keep plastic dusts contained within your system and prevent them from leaking out into open areas of your processing facility. If your process generates combustible dust, make sure you choose an NFPA-compliant valve to reduce the risk of fires and explosions in your plant.

A.
A rotary valve with an adjustable side inlet design, such as the S-Pellet Series, can protect plastic pellets, beads, and granules from shearing by controlling the flow of material. More standard valve designs can also be customized to handle the requirements of your plastics processing application, so check with your supplier to find the best fit.

A.
Material buildup and flow issues like bridging can happen when plastic resins flow through the system too quickly, or when your equipment lacks the proper accessories to handle flow issues. Ensure rotary valves are properly sized for your material, system, and desired rate of flow, and consider accessories such as shear protectors and air purge kits to prevent issues such as shearing, jamming, and buildup.
