Description
Kromschroder Hydraulic oil 74918683 is a specialized working fluid for use in Kromschroder VK series gas and industrial automation. It is used in hydraulic systems and actuators of the VK series, ensuring stable operation, precise control, and protection of internal components from wear. The oil maintains optimal viscosity for VK series systems, resists temperature changes, and is compatible with Kromschroder equipment. It is applied during maintenance, repair, and scheduled replacement of working fluid in boiler plants and burner control systems.
Further details
| Application oil burners | used in hydraulic systems and actuators of the vk series |
|---|---|
| Common failure modes | contamination or degradation of the oil can cause sluggish valve movement, hunting, or failure to reach the correct position, often reported as a modulation fault by the burner control |
| Function | working fluid in the hydraulic actuator that positions the gas valve plug in modulating burners |
| Key matching parameters | viscosity grade, operating temperature range, and compatibility with the valve's seal materials |
| Operating principle | actuator translates control signals from the burner control into linear movement, adjusting the gas flow rate in proportion to the fan speed and heat demand |
| Replacement considerations | drain and flush the actuator thoroughly if the previous oil is of unknown type or condition; do not mix oils of different viscosities or additive packages; use only oil explicitly specified by the valve manufacturer |
Choosing and fitting
Parts of this type are selected by viscosity grade, operating temperature range, and compatibility with seal materials. Before ordering, verify the valve model and the manufacturer's specified oil type. During replacement, drain and flush the actuator thoroughly if the previous oil is of unknown type or condition. Do not mix oils of different viscosities or additive packages.
Signs of failure
Contamination or degradation of the oil can cause sluggish valve movement, hunting, or failure to reach the correct position, often reported as a modulation fault by the burner control. Check oil level and condition if the valve response is inconsistent or slow.
