Easy to Operate

Each valve is individually accessed by a manual touch display, the included PC software, an external analog signal, or an external digital signal (TTL). An event marker pulse, generated each time a valve is switched on, is provided for chart recordings. A syncronization pulse can be generated by use of the trigger/sync connector (digital I/O, TTL) to line up valve triggering and recordings for optimum data analysis.


Pinch Valve Systems

Pinch valves are the simplest to maintain as the solution never comes in contact with the valve and tubings are easily changed.
Valves are dual acting (3-way) with both normally open and closed sides. A Y-connector at the valve input permits solution flow to waste with the valve off.

PTFE Valve Systems

PTFE valves are available for applications where resistance to chemicals is a concern. The valves are 2-way (either on or off).

Mini-Valve Systems

These systems are designed for slow flow perfusion where smaller diameter tubing is used. The mini-valves mount directly to a compact PTFE manifold. The 3-way valves allow for solutions to flow to waste if desired. The system is ideally suited for use with the SF-77C perfusion stepper systems.

Touch and PC Software controlled

Valve Control Systems


  • Up to 8 channels
  • Choice of 3 valve types: Pinch, PTFE, or Miniature Lee Valves
  • Low noise
  • Low self-heating design
  • Just one analog signal to control all valves


The system can be operated either manually via touch display or via provided PC software. Software and updates are free. An SDK ia available for integrating into your own software.
