Model HIT Corrosion-Resistant PTFE Body Control Valves OVERVIEW
No. SS2-8193-0200
Corrosion-Resistant PTFE Body Control Valves
Model HIT
OVERVIEW
The Corrosion Resistant PTFE Body Control
Valves (model HIT) are best suited for handling
corrosive fluids such as acids and alkali because
the wet parts are made of corrosion-resistant
materials. The valve body employs the structure
not affected by the pipe line stress.
The actuator utilizes a compact, powerful multispring diaphragm motor integrated with simple
mechanism.
