TYPE-8 AIRLOCK: ABRASIVE RESISTANT CERAMIC ROTARY VALVE

Magnum Systems’ abrasive-resistant rotary valve Type-8 airlock is a “paramedic” valve that rescues pneumatic conveying systems that, due to bad design, changes in material, or just bad luck, tend to wear out regular valves. It is also used as an “insurance” valve, installed in locations that are hard and expensive to get to, or used in applications in which it is expensive to shut down the system to replace a rotary valve. What makes the Type-8 our most abrasion-resistant rotary valve, is the closed-end rotor with tungsten carbide inserts on the tips and shroud. The housing is made from cast iron, but the entire bore is covered in ceramic tiles, with the leading edges having tungsten carbide inserts. The Type-8 rotary valve truly shines when coupled with our cavity air purge system on airlock applications.

All of our rotary valves are NFPA Section 12.2.3.2 compliant.
