Globe control valves BAELZ precisely control the flow rate of steam in steam systems.
What is a BAELZ Globe Control Valve?
BAELZ linear control valves are a line of industrial control valves from Germany, specifically designed to regulate the flow rate of steam, hot water, heat transfer oil, and other industrial fluids.
BAELZ valves stand out for:
• Precise linear control
• High stability
• PID compatibility
• Reduced hunting
• High temperature resistance
• Good sealing
Strong applications in:
• Steam systems
• Boilers
• Heat exchangers
• Textile dyeing
• Food processing
• Rubber
• Wood processing
• HVAC

BAELZ valve controls temperature and steam flow in a Steam System.
Steam System
Controls steam supply to the heating coil.
Heat Exchanger
Controls stable heat exchange temperature.
Boiler
Regulates steam supply according to load.
HVAC
Mixing or diverting.
BAELZ Valve Selection Experience
Based on practical implementation:
• Steam coil systems should prioritize 2-way valves
• Heat exchanger bypass systems should use 3-way valves
• If PID fluctuates strongly → choose a fast-response actuator
• If the load changes continuously → use a precise linear positioner
Common mistakes:
• Incorrect Cv selection
• Incorrect signal selection
• Incorrect fail action selection
• Incorrect flow arrow orientation
