Kromschroeder GEH20R10 (03352507) flow adjusting cock for gas

Gas adjustment cock (setting valve) Kromschroder GEH 20R10 (03352507) is a manual needle valve for precise adjustment of gas or air flow in burner fuel supply systems. The device allows smooth flow adjustment and position locking with a tool, which is necessary to ensure the correct gas-air ratio during burner commissioning and operation. Technical specifications: Parameter Value; Part numbers 03352507, 624.439.065; Model GEH 20R10; Manufacturer Kromschroder / Honeywell (Germany); Valve type Adjustment (setting); Nominal diameter (DN) 20 (corresponds to 3/4" connection); Connection type External thread R 3/4" and internal thread Rp 3/4" (combined); Maximum pressure (gas) 1 bar; Maximum pressure (air) 4 bar; Weight 0.21 kg. Key advantages: Precise flow adjustment: The needle mechanism allows smooth and metered change of gas volume to the burner for optimal gas-air ratio. Position locking: Changing the flow requires a tool, preventing accidental adjustment during operation. Versatility: When used with air, the valve withstands pressure up to 4 bar, making it suitable for both fuel and air lines. Certified safety: The valve is certified for gas operation, confirming compliance with high safety standards (DIN-DVGW). Reliability and quality: Original Kromschroder component, resistant to natural and liquefied gas, designed for long service life in industrial conditions. Installation recommendations: Sealing: Use sealing materials resistant to gas (e.g., gas-impregnated PTFE tape, special sealants).
