Valve/ Switch Combinations

The combination of a multipole electric switch with the Drallim valves heralds a new era in process safety systems. The introduction of an explosion category electric switch further enhances the applications to which these devices are applied.

Typical Applications

Typical applications are feedback to DCS systems, remote and local actuation of fire prevention and damping systems, graduated loading and unloading of compressors, starting and stopping pumping systems. The electric switches below can be fitted to the valves detailed within this catalogue with exception of those with a base entry connection.
