1. DEVICE DESCRIPTION
1.1. OPERATING PRINCIPLE AND CONSTRUCTION
The device is actuated by means of a horizontal sliding selector
which enables switching of the ports within approximately 0.10 sec.
It is therefore possible to change flow direction or to switch the flow
path, according to the type of installation.
The device is an all aluminum alloy construction. It is not subject to
contacts and interferences between the selector and device body.
The selector acts on special flexible teflon segments which ensure
efficient sealing between the flow chambers, and is returned and
kept in the basic position by means of a coil spring.
The device can be operated either electrically or pneumatically.
2. GENERAL INSTRUCTIONS
