THERMOSTATIC CARTRIDGE HYDROSTAT COAXIAL ST255
MAIN DATA

• Ø 66 mm
• Handle rotation 330°
• Flow opening/closing handle rotation 90°
• Plant pressure range 0,1-5 bar
• Recommended temperature range from 15° C to 65° C
• Recommended temperature differential 50° C
• Safety system in case of cold water lack
• Building materials:
- high performance thermoplastic materials
- low lead brass alloy
• Opertion:
- gas heaters
- electric storage heaters
- centralized installations

• Designed to be comply to:
o EN1111
o EN200
• Fixing ring torque 10 Nm

Information related to flow-rate and noise with the various resistances have to be measured from time to time with tap where the cartridge must be used.



OPTIONALS

• Customizable temperature handle stem
• Customizable on/off handle spline
• Hi-pressure version, comply to ASME/ASSE requirements

N.B.

Thermostatic cartridges are calibrated at the factory at 38°C ±1°C with a temperature differential of 50°C and 3 bar hot and cold water pressure. A new calibration is required in case of different values.




Dimensional features, technical data and optionals may change without notice as STSR carries on a constant activity of research, evolution and adaptation to the rules requirements of its products.
