Rotary Valves
Shick Esteve’s durable Rotary Valves are designed to meter a wide variety of dry, powdered, granulated or similar material into vacuum or pressurized pneumatic convey lines, as well as gravity applications. Rotary Valves are typically used at the discharge of bulk storage dust cosilos, bins, hand dumps, llectors or scaling hoppers. They are available in two configurations: airlocks (drop through) and feeders (blow through). Each product line comes in various materials of construction and is designed for a wide variety of applications. The airlocks and feeders are designed to handle a maximum pressure of 14.7 psig and maximum vacuum of 29 Hg. Close tolerances exceed NFPA standards for use as an isolation valve.
