Info

Project planning information The inlet pressure p e and the outlet pressure p G can be measured on both sides of the valve body. VAD: Measurement point for the gas outlet pressure p G on the governor body. > 20 mm The VAD, VAG may not be in contact with masonry. Minimum clearance 20 mm. p e p G p G p L VAG: Additional measurement point for the air control pressure p L on the governor body. VAD, VAG: To increase the control accuracy, an external impulse line can be connected to the pressure test point p G . a a GFK GFK VAD VAG Ensure that there is sufficient installation space around the flange screws and the actuator. Sealing material and thread cuttings must not be allowed to get into the valve housing. We recommend that a filter be installed upstream of every system. Installation Installation position vertical or horizontal, not upside down. > +80 ° C The solenoid body heats up during operation – up to 90°C depending on ambient temperature and voltage. To ensure that the air/gas ratio control VAG can react quickly when the load is changed, the impulse line p L should be kept as short as possible. Do not store or install the unit in the open air.
