Application Notes
- This valve is ideal for water, glycol, and compatible liquids in industrial mixing and diverting service.
- Shutoff pressure depends on flange rating; consult factory for higher-pressure needs.
- Actuator selection (EC vs ES) should match system safety and fail-position requirements.
Note: The HB Series stainless steel body and precision electric actuators make these valves suitable for demanding fluid control environments, including HVAC, industrial processing, and temperature control systems.
