Diaphragm single stage automatic switchover board with manual reset & with balanced valve - TD502

The TD502 switchover board is ideally suited to insure gas supply from many high pressure sources of high purity non-corrosive gases with high flow. The device is dedicated to supply of gas to analyzers and to create a controlled atmosphere in laboratories, control units, and for petrochemical applications.

Key advantages

Maintains purity: eliminates cross-flow mixing of supply sources
Possible to connect up to 6 cylinders without using the purge line
Outstanding pressure consistency with Balanced Valve Technology
Ready to install with all components pre-mounted on a board
Can be equipped with a collection tube on the relief valve and purge outlet
Can be equipped with an outlet shut-off valve
Using contact gauges, the switchover board can also be equipped with an alarm box to indicate the source status
