ACS Valves - Model MD Series -Rotary Valve for Metering, Feeding and Airlock Applications
FromACS Valves
For long-term savings, ACS designed this valve to reduce total lifecycle maintenance requirements. The MD Series housings are cast in North America and CNC-machined to precise tolerances, eliminating axial shaft movement, seal leakage, and shortened bearing life.
