RMG 658-DP

658-DP is a pilot for outlet pressure control (pd min and pd max) and differential pressure control (Δp). It can be used with standard gas pressure regulators according to DIN EN 334.

The pilot works with two outlet pressure stages, which may be set independently of each other – one to a lower (pd min stage), and the other to an upper (pd max stage) limit value. Control tasks between the two limit values will be handled by the differential pressure stage Δp. The transition between the functions of the stages is automatic.

Features and Benefits:

  • Pilot with automatic modular load-limiting stage, pilot stage pd min, pd max and differential pressure stage Δp
  • With inlet pressure and loading pressure gauges and upstream fine-mesh filter HON 905, also available with outlet pressure gauge (optional)
  • Optionally with vent valve RMG 915
  • Suitable for non-aggressive gases, other gases on enquiry
  • CE registration according to PED in combination with RMG gas pressure regulators
  • According to DIN EN 334, the pilot is an integral component of this device
  • Max. admissible pressure PS: 100 bar
  • Max. inlet pressure pu max: up to 100 bar
  • Outlet pressure range Wd
  • Outlet pressure pilot stage 1: 0.3 to 90 bar
  • Outlet pressure pilot stage 2: 0.3 to 90 bar
  • Differential pressure stage Δp: 0.05 bar to 1.2 bar
  • Load-limiting stage: 0.5 bar to 15 bar above pd

All mechanical components of this device are without potential ignition sources and/ or hot faces. They are not subject to ATEX 95 (94/9/EC). All electronic accessories, on the other hand, meet ATEX requirements.
