Actuator for DR and ZR valves with DN 15 - 65 diameter, 230V power supply, 3-point control signal, 20 Nm VMM20

Valve Actuator – Precise Control in Heating and Cooling Systems

This electric actuator, designed to work with DR and ZR series valves and dampers, is a reliable solution for controlling flow in heating and air conditioning installations. Its design based on a three-point signal ensures effective temperature regulation, and its solid construction guarantees long-lasting and trouble-free operation. The actuator works perfectly in systems with a glycol mixture (up to 50%), offering a wide range of operating temperatures from 2°C to 130°C.

Characteristics and Application

VMM series actuators are designed to control mixing valves with a rotating mushroom. Thanks to a torque of 20 Nm, they effectively open and close valves, allowing for precise temperature adjustment in rooms. The wide range of applications includes both heating and cooling installations, and optional connectors allow mounting on various types of valves and dampers. It is worth mentioning the possibility of use in combination with V5421B valves with diameters DN25 - DN150.

Functionality and Benefits

• Versatility: compatible with DR, ZR valves and V5421B dampers (DN25 - DN150).
• Precision: three-point signal control ensures accurate temperature regulation.
• Durability: solid construction and high-quality materials guarantee reliability.
• Wide temperature range: possibility of operation in the range of 0°C to 60°C ambient and 2°C to 130°C medium.
• Position indicator: equipped with a mechanical position indicator to facilitate monitoring of the valve status.
• Manual operation: possibility of manual control of the actuator in case of power failure or need for quick intervention.
• Expansion options: possibility of mounting optional auxiliary contacts for additional signaling functions.
• Long lifespan: confirmed by a 5-year manufacturer's warranty from the date of production – investment security for years!
• Compliance with standards: IP54 protection class ensures resistance to dust and moisture, allowing installation in various environmental conditions.
• Modulating control: enables smooth adjustment of the valve position, which translates into more precise maintenance of the set temperature.

Additional information: the cycle time is 96 seconds, and the maximum rotation angle is 90 degrees. The housing is made of plastic, which ensures lightness and corrosion resistance. Energy consumption in operating mode is only 3.5W, which translates into low operating costs.
