Pneumatic operated blocking valves

Download technical datasheet

The pneumatically operated blocking valve provides the opening/closing function and the automation of the latter in a single, space-saving product.
Its operation is independent of the upstream and downstream pressures of the circulating fluid.
It is available in two versions: "normally closed" and "double acting", and in two different materials: brass and stainless steel.
