Propane reducer, types, operating principle

A propane pressure regulator is designed to convert the pressure of propane-butane gas supplied from a cylinder and automatically maintain its operating pressure. Various models of regulators are available:

• BPO-5DM;
• BPO-5-4DM;
• BPO-5-10DM and others.

If you choose the propane reducer BPO-5-4DM, it has the following characteristics:

• maximum throughput capacity of 5.0 m3/h;
• maximum gas pressure at the inlet 2.5 MPa;
• working gas pressure 0.2 MPa.

This model provides good reliability, high precision and efficiency of gas supply, cost-effectiveness, and increased resistance to operation in severe frost.

Choosing a propane pressure regulator requires careful consideration, as working with gas, especially when the gas is under high pressure, is dangerous and challenging. The specifications of the proposed model, as well as documentation that provides specific quality and safety guarantees, can be very helpful in making your choice. Price also plays a significant role: the higher the price, the better the quality of the pressure regulator, and experience shows that this is generally true.

The BPO-4 propane pressure regulator features dual gas filtration and the option to install a safety device, such as a flame arrester or check valve, at the regulator outlet. This model also has a UHL climate rating, according to GOST 15150, for operation in temperatures ranging from -25°C to +50°C.

Models BPO-5DM:

• have a throughput of 5.0 m3/h;
• gas inlet pressure 2.5 MPa;
• working gas pressure 0.3 MPa, weight no more than 0.5 kg.

This universal model can be used with MAF gas systems. All pressure gauges on the pressure reducer have been thoroughly tested. It features two levels of protection for the pressure reducing unit, a mesh filter, and an EF-2 filter element. The design is robust and wear-resistant, with brass housing and fittings and a return flow of less than 0.1%.

The propane gas reducer is painted red and has an adjustment screw that can be used to set the required pressure for operation. The reducer's design is quite simple, but all of its individual components work very harmoniously, and the pressure gauge shows the adjusted pressure.

A household propane pressure reducer has a similar application for reducing gas pressure from a gas system for gas consumption and automatically maintaining this pressure for stable operation.

Household propane reducers are classified according to GOST 13861:

• according to the principle of direct and reverse action;
• by gas passed through;
• Depending on the application, they can be balloon or ramp type, and they can also be single-stage spring, two-stage, or single-stage pneumatic.

Input pressure parameters are up to 250 atmospheres for compressed gases, and 25 atmospheres for liquefied gases. After conversion, the output is 1-16 atmospheres, with flow rates ranging from tens to hundreds of cubic meters per hour. For 50-liter gas cylinders, a household propane reducer (RDSG1-1.2, 16/3.6 atmospheres, with a 9-gauge fitting) is suitable.
