Karl Dungs GasMultiBloc Multifunctional Gas Controls for Industrial Burners

Karl Dungs GasMultiBloc modular systems series MBE, MBC, and MB-DLE combine a fine-mesh filter, a spring-loaded pressure regulator, and two Class A automatic safety shut-off valves in a unified compact assembly.

Engineered for modulating and two-stage gas burner systems, the integrated design reduces gas train installation dimensions and eliminates intermediate connecting nipples. The unified housing withstands operating pressures up to 360 mbar with rapid shut-off response times under one second.

When requesting technical selection, provide inlet and required downstream gas pressure, maximum fuel flow rate, burner model, and electrical supply voltage.

Karl Dungs DMV and MVD Solenoid Safety Shut-Off Valves for Gas Lines

Fast-closing solenoid safety shut-off valves Karl Dungs series DMV, MVD, and SV provide automatic fuel gas isolation for boiler rooms and industrial furnaces.

Available in single and compact double valve configurations from DN 15 to DN 150, these units maintain Class A tightness with zero leakage under high pressure. DLE versions integrate a hydraulic damper to deliver smooth adjustable opening for soft burner ignition and flame stability.

The rugged aluminum body and high-temperature NBR seals ensure long operational life across demanding industrial environments. For technical inquiries, confirm pipeline bore size, working gas pressure, opening speed, and solenoid coil ratings.

Karl Dungs GW and LGW Pressure Switches for Safety Interlock Circuits

Karl Dungs diaphragm pressure switches series GW A5, GW A6, LGW A2, and LGW A4 monitor positive, negative, and differential pressures in gas and combustion air ducts. High-precision elastomeric measuring diaphragms actuate gold-plated microswitches, preventing false trips from industrial vibrations.

The devices safeguard burner firing by verifying minimum gas supply pressure, air blower draft, and filter differential loading. Weatherproof IP54 housings feature calibrated setting dials for convenient commissioning and tuning.

When ordering pressure switches, indicate process fluid, required adjustment range in millibars, electrical connection style, and manual reset lockout needs.

Karl Dungs FRS and FRM Spring-Loaded Gas Pressure Regulators

Karl Dungs pressure regulators series FRS and FRM deliver accurate pressure reduction and maintain stable downstream pressure despite fluctuating inlet pressures or changing burner demands.

An internal balancing diaphragm counteracts inlet pressure swings against the valve seat, increasing regulating accuracy across all firing loads. FRM models handle medium inlet pressures up to 1000 kPa, making them suitable for commercial and district gas reducing stations.

When dimensioning a gas regulator, state upstream supply pressure, target downstream operating pressure, flow rate variations, gas relative density, and pipeline flange standards.

Karl Dungs VPS 504 and VDK Valve Proving Systems for Seat Integrity

Automatic valve proving systems Karl Dungs VPS 504 and VDK test the closure tightness of dual solenoid safety shut-off valves before burner ignition or immediately after shutdown.

An integrated motor-driven diaphragm pump pressurizes the intermediate chamber between valve seats without venting fuel gas to the ambient boiler room. The electronic monitoring module measures pressure trends during a short testing cycle lasting 10 to 26 seconds.

When submitting an inquiry for a VPS system, specify the valve group model, intermediate test volume between valves, supply voltage (230 VAC or 24 VDC), and flanged adapter hardware.
