At M&F Tech Services, we recently completed the full servicing of a rotary valve, including the installation of new rotor blades and scraper blades. Rotary valves play a crucial role in many process lines, ensuring precise material dosing and acting as airlocks between areas of different pressures.
One of the key factors in servicing rotary valves is maintaining the correct clearances between the rotor, housing, and blades. Too much clearance can lead to leakage, efficiency loss, and product waste, while too little can cause metal-to-metal contact, excessive wear, or even equipment failure. That’s why our technicians always carefully inspect all components, ensure precise fits, and adjust clearances according to the manufacturer’s specifications — in this case, the tight tolerances required for a DMN valve. With the new blades and scraper blades installed, the valve is now ready to deliver reliable, efficient, and long-lasting performance.
