The SV0018 was designed for use in hemodialysis machines to mix the dialysate fluid and control the fluid removal from the patient. The valve body has two ports to connect to a silicone tube. It has a higher flow rate (4.3l/min) than the SV0016 and SV0017 (2.5l/min).
The following features provide superior benefits in hemodialysis machines compared to other valves on the market:
- PPSU valve bodies have better thermal and chemical resistance in comparison to PEI, which plays a role, i.e., regarding the risk of tension cracks
- PTFE bellows are maintenance-free and offer longer dialysis machine lifetimes than rubber bellows used in many machines.
- ISO 10993 certified (not only cytotoxicity), Rohs, and REACH compatibility.
- Designed for worst-case temperatures (T_ambient = 80°C while maintaining a 100% duty cycle).
- Bidirectional flow.
- Standard voltage is 24 VDC – other voltages are available.
- Greater than 3 bar pressure is possible depending on the application.
- Can also be used for food-grade applications, such as coffee machines
