Fisher Type B NG turar-joy regulyatorlari | Integratsiyalashgan xavfsizlikka ega yuqori samarali turar-joy regulyatori

Asosiy afzalliklari va afzalliklari

• Two-Stage Reduction for Constant Outlet Pressures: The B NG utilizes a two-stage reduction process. This ensures that the outlet pressure remains virtually constant, even if there are significant variations in the network inlet pressure. This provides superior performance for high-efficiency modern gas appliances.

• Integrated Slam-Shut Safety Valve: The built-in safety shut-off valve automatically cuts off gas flow in three critical scenarios:

  1. Excessive Flow: Protecting against major downstream leaks or broken lines.

  2. Low Outlet Pressure: Monitoring for high gas demand that exceeds safe limits.

  3. Low Inlet Pressure: Detecting network pressure drops or upstream pipe damage.

• Manual Reset Functionality: Once the safety function trips and the underlying issue is resolved, the regulator can be manually reset, putting control back in the hands of the technician or homeowner.

• Internal Relief Valve: To further enhance safety, the unit includes an internal relief valve across the diaphragm to vent excess pressure during minor overpressure events.

• Inlet Strainer: Every Type B NG comes equipped with a built-in inlet strainer. This captures pipe scale and debris before it can reach the valve seat, preventing damage and ensuring a long, maintenance-free service life.

• Compact and Interchangeable Design: The B NG features a space-saving footprint. Specifically, the Type B6 NG is designed with the same key dimensions as the older angle-shaped Type B6 N, allowing for easy drop-in replacement during utility upgrades.

• Factory Preset for Reliability: To ensure out-of-the-box accuracy and reduce installation errors, these regulators are factory preset to standard residential pressure requirements.
