For Heavy-Duty Industrial Service

Coperion Manufactures ZRD Rotary Valve in USA

The ZRD rotary valve from Coperion GmbH, Stuttgart, Germany, is specially designed for plastics, mineral, chemical and food applications. The valve is engineered for heavy-duty industrial service with pressure differentials up to 21 psi(g) and temperatures up to 212°F; higher temperature options are available. The ZRD is often used as a discharging and metering valve for conveying products in powder and granular form.

An extensive range of sizes is available, with large throughputs ranging from 500 to 400,000 + lb per hour (subject to bulk density and application). The valves have a pressure-surge-proof, (pressure shock) rating of 145 psi(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. An alternate seal option includes the popular T3 PTFE and quad ring assemblies, which eliminate the need for air purge. The ZRD comes with a sealed-for-life outboard bearing arrangement that can be supplied with and without air purge seals (separated from the product zone) by way of a dedicated relief openings

In order to shorten delivery times for customers of the Americas market, Coperion K-Tron located in Salina, KS, USA has started the US production of German-designed Coperion rotary valves type ZRD in Salina. 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 shorter delivery times. Standard grey cast iron and stainless steel ZRD rotary valves will now be available to customers within 4 to 6 weeks.
