HERZ Zone Valves are used in heating and cooling systems such as heat pump systems, floor heating and HVAC
applications as a zone management element.
HERZ ball valve is made from high-quality brass and has identical kvs value through AB-A and AB-B. Valves are
available from dimension DN20 up to DN32.
Designed for a multitude of applications including heat pump systems, floor heating, and HVAC setups, our ball valves serve as the cornerstone of zone management:
Usage in heat pump systems: diverting the flow from the preparation of domestic hot water and heating circuit:

Nominal pressure: PN10
Max. operating temperature: 110°C (no steam)*
*when Zone valve is used in combination with HERZ motor
actuator, ambient temperature must not exceed 50°C
Min. operating temperature: 0°C (water 0,5°C)
Working stroke angle (turn): 90°
Opening torque (at PN10): ≤ 5 Nm
Leakage rate: 0%
Medium:
Heating water purity in accordance to ÖNORM H 5195 and VDI- Standard 2035. The use of ethylene, or propylene glycol in a mixing ratio of 25- 50% is allowed. EPDM gaskets will be affected by mineral oils lubricants and thus lead to failure of the EPDM seals. Please refer to the manufacturer’s documentation when using ethylene glycol products for frost and corrosion protection.
