KRAFT Throttle Valves
KRAFT throttle valves from Germany regulate the flow of bulk solids, powders and gases; sizes DN 50 to DN 800, wafer or lug type.
Product Overview
KRAFT throttle valves control flow in pipelines carrying bulk solids and gases where full shut-off is not required. Several series cover different sizes, installation types and materials, and can be built to the customer's flange dimensions and requirements.
The valves are suitable for explosion-hazard areas (ATEX zones 0/20 to 2/22). Applications: thermal power, waste incineration, building materials, chemicals, pharmaceuticals, food and animal feed.
