Variable air/gas ratio controls for maintaining a constant gas/air pressure ratio of 4:1 on systems with air pre-heating, GIKH for continuous control, GIKH..B for high/low/off control, EC type tested and certified.
The magnetic relief valve VAN is designed to monitor gas valves for tightness used in conjunction with a visual discharge unit. It enables the purging of excess or leakage gas. The magnetic relief valve VAN is open when it is de-energized.
