HERZ 4037 Mixing & Diverting Valve from HERZ Armaturen is a precision-engineered 3-way control valve manufactured from dezincification-resistant DZR brass, CW602N, for corrosion resistance and long-term operational reliability.
The valve provides linear regulation of heating and cooling water or air in closed systems and can operate as either a mixing valve or a diverting valve.
Its stainless-steel spindle, glass-fibre-reinforced PTFE seat, and EPDM O-ring seals support smooth operation, dependable sealing, and minimal internal leakage.
The valve is designed for integration with compatible HERZ actuators and automation systems, supporting proportional and linear control in HVAC and hydronic applications.
Operating Conditions
- Nominal pressure rating: PN16.
- Operating temperature range from -15°C to +130°C.
- Nominal size range from DN15 to DN50.
Flow & Leakage Performance
- Linear flow characteristic.
- Mixing leakage below 0.02% of the Kv value.
- Diverting leakage of 1%.
- Suitable for mixing and diverting duties.
Actuator Compatibility
- Compatible with HERZ 7712 Series electric drives.
- Suitable for integration with HERZ automation systems.
- Supports proportional and linear control.
Accurate Flow Control
The linear flow characteristic supports accurate regulation in heating and cooling systems.
Minimal Internal Leakage
The valve design provides low leakage during both mixing and diverting operation.
Corrosion Resistance
DZR brass construction supports reliable operation and extended service life in water-based systems.
Automation-Ready Response
The linear response characteristic makes the valve suitable for automated HVAC and hydronic control.
Compact Installation
