INTRODUCTION

The Rada TF31 is a press action water flow control valve which automatically turns
the flow off. The full cycle is reactivated each time the flow button is pressed.

The flow rate is constant and is automatically turned off after a period of approximately
30 seconds. For economy in the use of energy and water an economical flow rate can
be obtained by adjustment of the internal flow adjuster.
