Custom Valves designed the SV0017 valve to mix dialysate fluid and control the fluid removal from the patient in hemodialysis machines. The valve body has two ports that connect to a silicone tube.

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 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
