Pneumatic conveying rotary valve ZVD

round-flange

The K-TRON ZVD series rotary valves serve as discharging valves for irregular fine and coarse grained products, such as regrind. They can also be used for regular pellets, that request increased purity levels, due to reduced dead zones that help prevent accumulation of residue. They are made via special inlet geometry principle, offering easy of handling and usability for heavy-duty industrial services. They show quality performance for differential pressures up to 1.5 bar, and temperatures up to 100 °C (212 °F). They are highly shock resistant (10 bar of pressure), contain a rotor with 10 blades, with open end and flat tips, and offer high filling effectiveness due to internal leakage gas venting. The inlet flange is round and drilled, per DIN PN 10 or ANSI 150 lbs. They also contain two NBR lip seals with labyrinth rings, that offer preparation for seal purge. They are also completely CE compliant.
