Customer Issue
A small espresso machine manufacturer needed a solenoid valve for a new espresso machine that met the following project requirements.
Project Requirements
- Withstand temperatures up to 100°C (212°F)
- Meet 5 bar system pressures
- Materials that resist coffees oiliness and acidity properties while meeting high temperatures
- Low cost
Custom Valve’s Solution
After testing, we found that Custom Valves’ standard dialysis valve was a perfect fit for the espresso machine. The valve’s wetted materials PPSU, PTFE, and FKM were able to meet the high-temperature requirements associated with making coffee, and that FKM seals would hold up against coffees’ oily properties.
The Result
Despite low manufacturing volumes, Custom Valves was able to provide a low-cost solution for this small manufacturer that met all system requirements and exceeded customer expectations.
