Fast coupler brass gas valve is a gas pipeline control device made of brass. It features a quick-connect design for easy connection and disconnection of pipelines, while providing on-off control for gas flow.
Core strengths
1. Quick Connect Design, Easy Installation and Disassembly
Tool-Free Operation: Uses a snap-on or rotary quick-connect design, requiring no tools for connection/disconnection, saving installation time (only 5-10 seconds per connection).
Sealing and Leak Prevention: Dual sealing rings (Nitrile rubber + PTFE), sealing pressure ≥0.3MPa, leakage rate ≤1×10⁻⁶ m³/h, effectively preventing gas leakage.
Wide Compatibility: Supports common pipe sizes such as DN15, DN20, DN25, and is compatible with domestic, European, and American pipeline interfaces, suitable for gas stoves, water heaters, and other devices.
2. Steel Handle Design, Durable Operation
High-Strength Steel Handle: Made of 304 stainless steel, tensile strength ≥520MPa, wear-resistant, impact-resistant, with a service life of ≥100,000 cycles.
Comfortable and Safe Design: Sandblasted anti-slip handle, torque ≤2N·m, easy to operate for elderly people and women.
Anti-Detachment Structure: The handle is fixed to the valve stem with dowels and reinforced with welding to ensure stability; optional lock control device, suitable for commercial and public spaces.
3. Gas-Specific Configuration, Safety Assurance
Valve Body Material: Made of HPB 59-1 brass, gravity-cast and precision-machined, resistant to gas corrosion, withstands high pressure (≤0.1MPa), and operates in temperatures ranging from -20°C to 60°C.
Sealing and Valve Core: The valve core is precision-machined and pairs with a PTFE modified valve seat for zero-leakage sealing; graphite + PTFE mixed packing reduces friction and ensures smooth operation.
4. Compact Structure, Wide Application
Space-Saving: The quick-connect design eliminates the need for reserved space for wrenches, making installation possible in tight spaces (e.g., inside cabinets or behind wall-mounted boilers), suitable for small apartments or densely piped environments.
Universal Compatibility: Supports various bellows specifications (e.g., φ9.5mm, φ16mm) to meet different flow requirements; one end has a quick-connect interface and the other end has male/female threads, flexibly connecting to gas meters, stoves, water heaters, etc.
5. Additional Safety Features (for Some High-End Products)
Automatic Locking Device: After the bellows are inserted, the locking ring automatically engages to prevent accidental disconnection (requires pressing the unlock button for disassembly).
Overflow Cut-Off Function: In case of abnormal gas flow (e.g., rapid leakage due to pipe rupture), the internal mechanism automatically shuts the valve to cut off the gas supply.
Anti-Static Design: Brass material is conductive, preventing static buildup from gas flow and reducing safety risks.
