Product data sheet Valveco 010…032: 2-way regulating valve for dynamic hydronic balancing How energy efficiency is improved Automatic dynamic hydronic balancing with the SAUTER Valveco regulating valve provides correct supply to the consumers and a reduction in temperature variations in the room, so that energy use is more accurate and more efficient. Regulating valve with three functions: Control, preset maximum volume, automatic flow regulation Large volume flow range: 30…3600 l/h Simple presetting of maximum volume flow without dismantling the actuator Control range 15/20…400 kPa = max. Δp over the valve Easy fitting of pressure measurement nipples Control passage A–AB is closed when the spindle is moved in Closing against the pressure Stuffing box is replaced under system pressure Slight adaptation of the proven SAUTER actuator technology Regulating valve with male thread as per DIN/EN ISO 228-1 Flat-sealing regulating valve (with conical sealing surface for DN 20, without insert) Differential pressure across the control unit is kept constant; valve authority 1 Valve body made of dezincification-resistant (DZR) brass Stainless-steel spindle Plug of PTFE Technical data Parameters Nominal pressure Valve characteristic Leakage rate Ambient conditions Operating temperature Operating temperature of valve in combination with AXT211, AXS215 and AXM217(S): Operating temperature at valve Maximum operating pressure Pressure and temperature data Flow parameters Overview of types Type Nominal diam- Volume flow eter setting range Accessories Type 1 threaded sleeve, R⅜", flat-sealing, DN 10, with cap nut and flat seal 1 threaded sleeve, R½", flat-sealing, DN 15, with cap nut and flat seal 1 threaded sleeve, R¾", flat-sealing, DN 20, with cap nut and flat seal 1 threaded sleeve, R1", flat-sealing, DN 25, with cap nut and flat seal

Product data sheet Pressure differences with thermal actuators Actuator Control signal ∆p [bar] Closes against the pressure Cannot be used to close with the pressure Description of operation When the spindle is pressed in, the regulating valve is closed. It is returned by the spring force from the spring in the valve. The valve can be controlled to the OPEN or CLOSED positions with the thermal actuator for unit valves AXT 211. Used in combination with the “normally closed” version of the actuator, the control passage of the valve closes in the event of a power failure. The valve can be controlled...

Example of volume flow Example function: DN 15 VCL015F210 with preset max. volume flow 210 l/h Volume flow as a function of the control voltage (e.g. 0...10 V continuous control) and the differential Minimum differential pressure The required minimum differential pressure (min. Ap) over the valve can be found in the diagrams. The system can be set precisely to this value using the two pressure measurement nipples. Design benefits • Minimal labour time is needed in order to specify the components for hydronic balancing (only the volume flow data is needed) • The valve authority does not have to...

Product data sheet Engineering and fitting notes So that impurities are retained in the water (e.g. weld beads, rust particles, etc.) and the differential pressure controller is not damaged, dirt filters must be fitted (e.g. on each floor or pipe run) (see accessories; observe the temperature range and the application, depending on the type). Requirements for water quality as per VDI 2035. All SAUTER Valveco valves must be used in closed circuits only. An excessively high oxygen mixture may damage the regulating valves in open circuits. To avoid this, an oxygen binding agent must be used; compatibility...
