Dialysis machines are complex and require long term reliability of every component – it’s not as simple as switching flow on/off. Valves cannot cause flow variations that might upset the volumetric balance of dialysate solutions. Our dialysis solenoid valves control the mixing of dialysate fluid and fluid removal from the patient.
A dialysis machine manufacturer required a high-quality, high-flow, maintenance-free valve in a compact envelope for their application.
Custom Valves’ isolated solenoid valve technology with PTFE bellows provided the perfect solution.
The customer required a smaller solenoid valve for their dialysis machine. Custom Valves was able to integrate a single valve in the customer’s manifold to save not only space, but money by reducing the amount of silicone tubing needed and allowing components to be easily exchanged for easy maintenance.
The typical pressure tightness for a dialysis valve is 3 bar. But since the water inlet pressure is higher than in the rest of the machine, this dialysis manufacturer required a special solenoid valve with a pressure tightness of 6 bar. Custom Valves rose to the challenge and designed a valve that met all customer requirements.
