Dapatkan Penawaran resmi,Harga dan Lead Time untuk membeli kebutuhan proyek Anda melalui website distibutoralatindustri The BelGAS P143 Relieving Gas Pressure Regulator is a direct-operated, spring-loaded pressure reducing regulator designed for accurate control of natural gas, propane, air, and other non-corrosive gases. The regulator features an internal relieving mechanism that automatically vents excess downstream pressure, providing additional protection to gas systems without requiring an external relief valve. It is widely used in commercial, residential, and light industrial applications, including burners, unit heaters, boilers, generators, and HVAC equipment.

The P143 Series is recognized for its compact design, reliable pressure control, high flow capacity, and simple maintenance. It is also available with an optional Low Pressure Cut-Off (LPCO) function and an internal monitor version (P143M) for enhanced overpressure protection.
Product Description
The BelGAS P143 Relieving Gas Pressure Regulator is engineered to reduce higher inlet gas pressure to a stable, controlled downstream pressure for safe and efficient operation of gas-fired equipment. Its direct-operated mechanism uses a large diaphragm and adjustable spring assembly to maintain precise outlet pressure under varying flow conditions. The built-in internal relief valve automatically releases excess downstream pressure when the set pressure is exceeded, helping protect connected equipment from over-pressurization.
Constructed with a durable cast iron body and aluminum bonnet, the regulator provides excellent mechanical strength and long service life in demanding environments. The nitrile diaphragm and seat materials ensure compatibility with natural gas, propane, and compressed air applications. Multiple port sizes, orifice options, and spring ranges are available to accommodate various installation requirements and flow capacities.
