- 1 - 3rd edition No. SS2-8193-0310 Corrosion-Resistant Type Small Size Ceramic Control Valves Model HMC OVERVIEW The Corrosion-Resistant Type Small Size Ceramic Control Valves (HMC) employs high-performance ceramic with excellent corrosion-resistant capabilities on entrire surfaces of body and trim in contact with fluids. Thus, the HMC are best suitable for control of corrosive fluids such as acid and alkali. The multi-spring type diaphragm motor with small size and large output is used for actruator, resulting in minimizing installation space.
