Reliable, durable, low-maintenance shut-off valve for powder processing

When used in pairs the valves, fitted with a safety vented spool, form an airlock for the safe loading of components into dangerous processes. They are often used in toxic or hazardous environments. Not only do they constantly control the flow of product, they insure it stays within the system and that it does not leak into the atmosphere. The valves also perform well under pressure and at elevated temperatures, according to the manufacturer.
