Combination Gas MultiBloc Valve Train Assembly

About this part

Multi-functional monoblock gas safety control unit for compatible atmospheric and forced-draft gas burners on industrial steam boilers. Depending on the exact model, the assembly can combine a gas filter, pressure regulator, and dual safety solenoid shutoff valves in one housing to support controlled ignition and rapid gas isolation.

Key features

• Integrated 4-in-1 design: Filter, Pressure Regulator, Fast Valve 1, Adjustable Slow-Opening Valve 2
• Soft-start hydraulic damping on main valve for shock-free burner ignition
• Adjustable outlet governor pressure for precise air-to-fuel ratio control
• Integrated pressure test points upstream and downstream
• Class A safety shutoff conforming to EN 161 gas appliance directives

Typical applications and wear

Natural gas, LPG, and biogas fired industrial steam boilers and burners. Wear involves internal diaphragm fatigue, solenoid coil degradation, and filter clogging.

Compliance

Use as part of a documented gas-train safety system; valve class, certification, and local gas-authority requirements must be confirmed for the installation.
