Two for the right mix
The ebm-papst D01 and E01 gas valves are ideally suited for condensing units with pneumatic composite controls. Depending on the pressure generated in the venturi of the gas blower, the gas valves are controlled pneumatically. The offset (shift in zero point) can be adjusted at the servo controller. At the same time, the desired gas quantity is adjusted using an integrated flow control element. Depending on the design, reference pressure can be connected to the servo controller if required.
The advantages of gas valves from ebm-papst:
- Precise setting of the air/gas ratio
- Compensation of pressure fluctuations in the supply network
