Functional Data:

- Fluid: Cold and warm water, water with glycol up to max. 50% vol.

- Fluid Temperature: -10...120°C [14...248°F]

  - Note: At fluid temperatures of -10...2°C, a spindle heater or valve neck extension is recommended. Fluid temperature limits may vary based on the actuator type.

- Close-off Pressure ∆ps: 1400 kPa

- Differential Pressure Δpmax: 350 kPa

  - Note: 200 kPa for low-noise operation

- Flow Characteristic: Equal percentage (VDI/VDE 2173), optimized in the opening range

- Leakage Rate: Air-bubble tight, leakage rate A (EN 12266-1)

- Angle of Rotation: 90°

  - Note: Operating range 15...90°

- Pipe Connection: Internal thread according to ISO 7-1

- Installation Orientation: Upright to horizontal (in relation to the stem)

- Servicing: Maintenance-free

 

Material Composition:

- Valve Body: Nickel-plated brass

- Closing Element: Stainless steel

- Spindle: Stainless steel

- Spindle Seal: EPDM O-ring

- Seat: PTFE, O-ring EPDM

- Characterised Disc: ETFE

 

Product Features:

Operating Mode: It is adjusted by a rotary actuator controlled by a commercially available modulating or 3-point control system. The ball of the valve (throttling device) moves to the position dictated by the control signal.

- Flow Characteristic: The integrated characterising disc ensures Equal percentage flow control.

 

Additional Accessories:

- Electrical Accessories:

  - Stem heater DN 15...50 (20 W) - Type: ZR24-2

- Mechanical Accessories:

  - Valve neck extension for ball valve DN 15...50 - Type: ZR-EXT-01

  - Pipe connectors for ball valves with internal thread:

    - DN 15 Rp 1/2" - Type: ZR2315

    - DN 20 Rp 3/4" - Type: ZR2320

    - DN 25 Rp 1" - Type: ZR2325

    - DN 32 Rp 1 1/4" - Type: ZR2332

    - DN 40 Rp 1 1/2" - Type: ZR2340

    - DN 50 Rp 2" - Type: ZR2350

 

Installation Notes:

- Permissible Installation Orientation: The ball valve can be installed upright to horizontal, but not in a hanging position (spindle pointing downwards).

- Water Quality Requirements: Adhere to VDI 2035. Ensure valves are free from particle debris. Installation of a suitable strainer is recommended.

 

 

Why You Should Buy:

- Reliability: Designed for robust performance in HVAC systems.

- Efficiency: Optimized for low-noise and efficient fluid control.

- Durability: Constructed from high-quality materials, ensuring long-lasting operation.

- Ease of Installation: Flexible installation orientations and maintenance-free design.
