Corrosion-Resistant Type Small Size Ceramic Control Valves Model HMC OVERVIEW
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.
