| VCL010..032: 2-way control valve Valveco
How energy efficiency is improved
Automatic dynamic hydraulic balance with the SAUTER Valveco control valve ensures correct supply to the consumers and a reduction of temperature fluctuations in the room, so energy use is more accurate and more efficient.
Areas of application
The multi-function valve is used for accurate flow control for air-conditioning, cooling and heating equipment such as fan-coil units, chilled beams, central underfloor heating systems, recirculated-air units and installation sections in conjunction with the AXT211 thermal actuator for unit valves, the AXS215S continuous actuator for unit valves or the AXM117(S) motorised actuator for unit valves.
Features
- Control valve with three functions: control, preset maximum volume, automatic flow regulation
- Nominal diameters DN 10, DN 15, DN 20, DN 25 and DN 32
- Wide range: 30...3600 l/h
- Simple presetting of maximum volume flow without having to dismantle the actuator
- Control range 15/20...400 kPa = max. Δp across the valve
- Linear characteristic
- Simple to fit the pressure measurement nipples
- When the stem is pressed in, the valve is closed
- Closes against the pressure
- Stuffing box can be replaced under system pressure
- Slight adaptation of the tried-and-tested SAUTER actuator technology
Technical description
- Control valve with external thread to DIN EN ISO 228-1
- Flat-sealing control valve (the DN 20, without the insert, has a conical sealing surface)
- Differential pressure over the regulating unit is kept constant; valve authority 1
- Valve body of dezincification-resistant (DZR) cast brass
- Plug of Teflon (PTFE)
- Stem of stainless steel
- Medium temperature range -10...120 °C
