Applications

• For extractive gas analysis
• For emission and process monitoring
• For switching over of several measuring points to one analyser
• For "hot gas" analysis, e.g. with FTIR

Benefits

• No influence on pressure conditions in the analysis system resp. the measuring value due to absolutely constant internal volume of the ball
• Valves in contrast to solenoid valves
• Maximum operational safety
• No damage of the analyser in case of failure
• No change of sample gas
• No cold spots
• Low noise operation also in case of switching
• Low and easy maintenance effort
• Easy mounting and integration in gas analysis systems

Features

• For 2 to 4 measuring points
• For 19" rack mounting, 3HU or 4HU
• Consistent heating
• Controlled heating up to max. 220 °C
• Low and excess temperature status contact
• "Fail Safe" condition in case of power failure
• Power supply 115 or 230 VAC 50/60 Hz
• Stainless steel ball valves with full bore for switching over the measuring points
• Pneumatic actuators for switching the ball valves
• 3/2-way solenoid valves for control of the pneumatic actuators
• Silencer at ventilation outlets of solenoid valves
• Optical shift indication
