Heated Vacuum Isolation Ball Valve
Overview
Heated Vacuum Isolation Ball Valves are designed with a heater specifically made for the ball. These valves have been designed such that the valve body and actuator are separated by an elongated actuator shaft, allowing the entire valve to not only be heated but insulated from heat loss. The unique ball valve heater covers the entire valve body as well as the heatable stainless steel flange clamps on its ends, protecting from heat loss, maximizing the temperature stability inside the valve.
- KF 40 and KF 50
- Designed with straight-through flow paths and less sensitive to contamination
- Designed for heated use up to 150°C
