VCS Computer-controlled Valve Control System

Product Summary

The Valve Control System lies at the heart of a multi-valve perfusion system designed to automate and control the delivery of solutions to imaging and recording chambers. The flexible design of these systems allows it to be used in diverse applications. The VCS systems are configured to control up to 8 Pinch, PTFE, or Mini valves.


  • Digital or analog switching for Patch Clamp applications
  • UI programmable valve protocols
  • Save and load protocols on hard drive
  • Download protocols to valve controller for permanent storage
  • Run and monitor protocols

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

The mini valve systems are available in standard size tubes, and with large tubes to support higher flow rates. The standard sized tube model is the most commonly used and is what is supplied with our VCS-77 systems. This is also the preferred tube size for applications using our SF-77C Fast Stepper.

We also have a large tube (LT) version available which is identical to the standard version except the valve input and output tubes have larger ID to permit flow rates up to 10 ml/min.

In all cases, 3-way valves can be configured as strict on/off or as continuous flow to waste if desired. The mini valve systems are ideally suited for use with the SF-77C perfusion stepper systems.

Valve Control Systems

Touch and PC Software controlled


  • 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.

The current VCS software can be downloaded here.
