C2..QP(T)- Zone Valve

Overview:

The C2..QP(T)- series presents a line of PI Zone Valves designed for 2-way control in closed cold and warm water systems. These valves are tailored for modulating control in air-handling and heating systems on the water side. With an internal thread design, they offer easy installation and reliable operation in various applications.

Key Features:

  • Versatile Application: Suitable for closed cold and warm water systems, including those with water-glycol mixtures up to 50% vol., making them adaptable to a range of HVAC setups.

  • Modulating Control: Specifically engineered for modulating control in air-handling and heating systems on the water side, ensuring precise and efficient regulation of flow.

  • Snap-Assembly: Features snap-assembly of the actuator, facilitating quick and hassle-free installation, saving time and effort during setup.

  • Durable Construction: Constructed with high-quality materials such as brass valve body, stainless steel closing element and stem, EPDM seals, and PTFE seat, ensuring longevity and reliability in operation.

Technical Specifications:

  • Fluid Compatibility: Cold and warm water, water with glycol up to 50% vol.
  • Fluid Temperature: -20°C to 120°C (with actuator: 2°C to 90°C)
  • Differential Pressure: 16 kPa to 350 kPa
  • Close-off Pressure: ∆ps 1400 kPa
  • Flow Characteristic: Equal percentage (VDI/VDE 2178), optimized in the opening range
  • Pressure Stability: ±5% with a pressure value of 35 kPa to 350 kPa; ±10% with a pressure value of 16 kPa to 35 kPa

Installation and Maintenance:

  • Pipe Connection: Internal thread according to ISO 7-1, allowing for easy integration into existing piping systems.
  • Installation Position: Can be installed upright to horizontal in relation to the stem, providing flexibility in placement.
  • Servicing: Maintenance-free design, ensuring hassle-free operation and reduced downtime.

Terms and Abbreviations:

  • V'nom: Nominal flow with valve completely opened
  • V'max: Maximum flow, set by the angle of rotation limitation on the actuator
  • Sv: Rangebility kvs/kvr
