Rotary Valves (airlocks)

Modern conveying systems require reliable and economical rotary valves. Pelletron developed new energy saving rotary valves including a special device to avoid the cutting of granular products. Valves are designed in stainless steel or with an aluminum, hard-coated housing and stainless steel rotor. For special applications, Pelletron provides quick clean rotary valves, powder valves and blow-through valves. Polished valves and valves with v-shaped rotors, shallow rotors and other special designs are also available.

Rotors

Pelletron rotors are all made of stainless steel and are available with various designs to meet the needs of a variety of applications. The standard rotors for granular products are closed end rotors with patented expanded tips and 10 or 12 vanes, depending on the conveying pressure. The standard rotors for powder products are open end rotors with beveled tips and 10 or 12 vanes, depending on the conveying pressure.

Dosing Rotor

Dosing Rotor

The dosing rotor is a special design with numerous chambers (pockets) and is available for volumetric dosing of material.

Shallow Pocket Rotor

Shallow Pocket Rotor

The shallow pocket rotor is a special design with rounded flat chambers (pockets) and is available for reduced discharge of material.

V-Shaped Rotor

V-Shaped Rotor

The V-shaped rotor is a special design for discharge and conveying of chips, regrind and other uneven materials.
