The SoftTouch 2 automated ball valve (female threaded BSPP), DN 15 up to DN 50, is developed specially for the HVAC market.

Two-Way and Three-Way Assemblies

  • Chilled Water
  • Hot Water
  • Steam

The SoftTouch 2 (ST2) series characterized ball valves provide accurate and cost effective control of a wide range of equipment in HVAC applications. The ST2 series features a forged brass 2-piece body with Stainless Steel balls and stems for water temperature up to   140 °C and saturated steam up to 103 kPa – 121°C.

The Amodel® Flow Characterizing Disk maintains equal percentage Flow Characteristics for optimum temperature control. The blowout-proof stem and mounting flange, combined with an innovative double O-Ring stem seal and self-centering stem bushing design provides quick and easy electric actuator field mounting while ensuring long life and leak-free valve performance.

Graphite reinforced PTFE seats backed with EPDM O-rings significantly reduce operating torque, allowing the use of the most economical actuator to provide the torque required for the application. All valve and actuator assemblies provide 1.38 kPa close-off pressure while ensuring operation after long idle periods. Because of their cost- effective, reliable design, the ST2 Series Ball Valves are maintenance free. The six different 24 V AC, non-spring return and spring return actuators are easily combined in-situ.
