This detailed product description showcases the superior quality excess flow stop valve offered by Wieländer+Schill, an ideal accessory for body repair and semi-industrial applications, especially for the safe and precise execution of brazing processes. The purpose of the valve is to immediately shut off the gas flow in case of abnormal flow conditions (excess flow), thereby increasing occupational safety and protecting the system.
The excess flow stop valve with part number 808028 is a robustly designed safety component specifically intended for pressurized gas lines. Its main function is to automatically shut off the gas supply if a flow rate higher than designed is detected on the consumer side, which is often an indication of a leak or pipe rupture.
This model With R3/8″ internal thread (i.l.) connection features both an inlet and an outlet side, ensuring standardized and reliable fitment for appropriate high-pressure hoses and equipment.
Main Advantages:
Safety: Immediate reaction in case of overflow, minimizing the risk of accidents.
Reliability: Solid brass construction guarantees long service life and corrosion resistance.
Compatibility: Ideal accessory for use with high-pressure hoses compliant with DIN 4812.
The precise performance and physical characteristics of the valve are summarized in the following table:
| Property | Value | Note |
|---|---|---|
| Part number | 808028 | |
| Material | Brass | Excellent durability and resistance. |
| Connection | R3/8″ × R3/8″ i.l. | Internal thread connections on both sides. |
| Flow Rate (Max.) | 3 kg/h | The maximum flow capacity safely manageable by the valve. |
| Operating Pressure (Max.) | 2 bar | Compatible with low and medium pressure soldering systems. |
| Weight | 0.140 kg | Lightweight yet robust design. |
This excess flow stop valve is an essential safety component in the following areas:
Body Repair: Especially during soldering operations where gas (e.g., propane, LPG) usage is essential.
Semi-Industrial Workshops: General welding and soldering applications where gas line integrity is critical.
Occupational Safety Regulations: Helps comply with strict occupational safety requirements when operating pressurized gas systems.
For safe and efficient work performance, the ideal accessory for the 808028 stop valve is the following high-pressure hose:
This high-pressure hose has been specifically optimized for brazing work and fits perfectly with the stop valve.
Main Features:
Szabvány: Design compliant with DIN 4812 standard.
Material: Made from special rubber compound, with textile reinforcement.
Frost Resistance: Extremely frost-resistant thanks to the special rubber compound, making work possible even up to -30°C.
Pressure Resistance: Suitable for all soldering work where the operating pressure reaches 2 bar.
Pre-installed connectors: Both ends of the hose are pre-fitted R3/8″ left-hand thread connectors, ensuring quick and professional installation.
The combined use of the hose with part number 808025 and the shut-off valve 808028 guarantees the safe and reliable operation of the system even under the most extreme conditions.
