3/4-Way Contiflow Valve
valve unit for continuous media conveyance
This valve unit combines two independently switchable 2/2-way valves and a pressure sensor in a compact design to a novel 3/4-way valve. This assembly is perfectly suited for continuous media conveyance with two neMESYS syringe pumps. Due to the integrated pressure sensor and the possibility to close the valve completely, the pressure of the inactive pump can be adjusted to the application pressure in a continuous flow. This minimizes the pressure pulse and thus the flow rate change during switching which results in an extremely uniform continuous flow.
Advantages
- 3/4-way valve with completely closed switching position
- integrated pressure sensor
- compact size
- easy connection to neMESYS I/O interface
- adapter plates for different neMESYS pumps
- integrated screw-in syringe holder for easy fluid connection
- indication of switching position by LEDs
Suitable for different pumps
The perfect complement for your neMESYS pumps
By using different base plates the valves can be used with neMESYS Low- and Mid Pressure syringe pumps. The mounting of the valve is extremely simple and also the exchange of the unit is done quickly.
Suitable for:
Various material combinations
For optimum media compatibility
The valve unit is available in a variety of material combinations, allowing improved media compatibility for various applications. Depending on the application and the media to be dosed, you can choose between these two valve variants:

3-4-Way Contiflow Valve 10 bar
Wetted materials: PPS, FKM, AI2O2

3-4-Way Contiflow Valve 5 bar
