The SQM40/SQM41 actuators are suited for driving oil pressure controller, butterfly valves, dampers or for use on other applications that require rotary motion. Areas of application are oil and gas burners of medium to higher capacity as well as thermal process plants.

• In connection with modulating 3-position controllers or continuous controllers (e.g., 4…20 mA) and/or
• directly by burner controls

Technical description The VPS 504 is the valve proving system for DUNGS multiple actuators. The valve proving system complies with EN 1643:
- Equipment operates independent of residual pressure in the range of the permissible operating range.
- Test volume ≤ 4 l
- Setting work not necessary on site
- Short test period: min. 10 s, max. 26 s
- Tightness or leaks are displayed by an LED
- External fault display possible for series 02, series 04 and S05
- Group fault alarm optional for S01 (SSM)
- Suitable for TRD systems
- Electrical connection possible by plug connection S01, 02, 03. No rewiring is required for contact allocation as per DIN 4791.
- S04 and S05: electrical connection at screw terminals via PG 13.5 cable entry
- Art. Nr. (219881) 

Description: Single-stage solenoid valve, normally when closed, fast opening, fast closing, manual limitation of flowing gas volume by adjusting main volume.

-Connection G 1/8” ISO 228
-Temperature range -40 °F to +150 °F (-40 °C to +65 °C)
-Materials Brass housing (standard version) or stainless steel NBR based rubber
