DZR Brass Pressure Independent Control Valve

Features and benefits

• Accurate and stable control of the flow rate of water determined by the operating spindle position independent of the circuit pressure changes
• Flow accuracy ±5% of max flow or ±10% of set flow, whichever is greater
• Test points, where fitted, are used for verification of the necessary operating pressure
• Can be used with actuator as a full pressure independent control valve or without actuation as a constant flow regulator
• With threaded M30x1.5 connection for linear actuator
• Maximum operating differential pressure of 400kPa
• Full stroke modulation independent from the presetting
• Separate flow rate adjuster allows control modulation to always use the whole valve stroke
• Can be fitted on the flow and return (flow must be in direction of arrow on the body)
• Easy setting of the graduation scale
• Suitable for heating and chilled water systems
• Temperatures from -10 to 130°C. Pressure rating max 20bar up to 100°C and max 10bar up to 130°C
• Ethylene glycol or propylene glycol mixtures up to 50% may be used
• Threaded F/F ISO 7/1
• Compatible with threaded pipe. For use with other piping systems, threaded adapters are required from the piping system manufacturer
