Combining German designs with American production, Coperion K-Tron recently began manufacturing its Coperion ZRD rotary valves at its Salina, KS facility, resulting in shorter delivery times for bulk solids industry customers in the U.S.

Coperion and Coperion K-Tron will appear this April 24-26, 2018 at the International Powder & Bulk Solids Conference & Exhibition at the Donald E. Stephens Convention Center in Rosemont, IL to showcase the new American-made valves, as well as the firm’s next generation of pharmaceutical loss-in-weight screw feeders, and a range of other feeder, pneumatic conveying and systems engineering solutions.

Geared toward end users in plastics, minerals, chemicals, and food industries, Coperion’s ZRD rotary valve offers pressure differentials ranging from 21 psi(g) [1.5 bar(g)] and temperatures up to 212°F [100°C], with additional options for higher temperatures available. The company offers a large array of sizes, featuring throughputs from 50 lb/hr to 400,000+ lb/hr, depending on the material’s bulk density and the specific application.

The valves have a pressure-surge-proof, (pressure shock) rating of 145 psi(g) [10 bar(g)], and are suitable for isolation according to NFPA standards (for select sizes up to 12 inch). The ZRD comes standard with air purged seals completely mounted with plastic or stainless-steel tubing, solenoid and filter regulator with gauge. Standard seal option includes the popular T3 PTFE and quad ring assemblies, which eliminate the need for air purge in most applications. In addition, the ZRD comes with a sealed-for-life outboard bearing arrangement, separated from product, with and without purge gas by way of a dedicated relief opening.

Local production of the valves, along with a considerable investment of stocked inventory, will allow Coperion to deliver and repair valves for the Americas market with significantly shorter delivery times. Standard grey cast iron and stainless steel ZRD rotary valves will now be available to customers within 4 to 6 weeks.
