1. Gas pressure regulator specifications and models
Although the specifications and models of gas pressure regulators produced by each manufacturer are similar, there are still certain differences. The specifications and models of gas pressure regulators mainly include the following:
1. Medium and low pressure gas pressure regulator series
RTJ50-0.4TB99Q series gas pressure regulators Pressure regulator
RTJ-0.4 Reynolds-type series gas pressure regulator
RTZ0.4-1.6AQ series direct-acting gas pressure regulator
RTZ50-0.4FQ Type gas pressure regulator
RTZ50-0.4TQ type gas pressure regulator
RTZ-0.4A series direct-acting gas pressure regulator
RTZ-0.4 JK series monitored gas pressure regulator
RTZ-0.4LQ series gas pressure regulator
2. High and medium pressure gas pressure regulator
CG high-pressure pressure regulator
RTJ-DK, DKQ series gas pressure regulator
RTJ-ZL axial flow gas pressure regulator
RTZ-1.6XG series gas pressure regulator
RTZ-G, GQ series gas pressure regulator

8. Nominal pipe diameter: DN25, DN50, DN80, DN100, DN150, DN200.
3. How to choose a gas pressure regulator
1. Choose a suitable gas pressure regulator according to the model and parameters, such as matching different outlets. pressure requirements, optional ultraIt has pressure cut-off, full discharge function, and pressure regulating monitoring function. It is suitable for civil and industrial and commercial users, etc. It is necessary to choose specialized gas pressure regulator equipment accordingly.
2. Choose according to your actual needs and affordability. When choosing a gas pressure regulator, customers cannot blindly pursue high quality. They must choose the one that suits them and can meet the actual requirements but not the other way around. If it puts too much burden on the work, it is better to have good quality and good price.
3. After-sales service is a very important factor to consider when purchasing equipment. As we all know, gas equipment is a very professional equipment. If a problem occurs during use, professional technicians will be required to repair it. If the manufacturer provides after-sales service, it will be much more convenient. Just contact the manufacturer to solve the problem.
4. Things to note when purchasing a gas pressure regulator
1. Do not buy one with adjustable pressure. In order to cater to the market, some manufacturers produce products with adjustable pressure, but this is not allowed by national standards. If the pressure is too high, the heat load of the gas appliance increases and the thermal efficiency decreases. This not only wastes energy but also produces toxic gases due to insufficient combustion, which may poison users.
2. Check the outer packaging to see if there is detailed name, address, phone number and other contact information of the manufacturer; check whether there is a production license number on the regulator shell. Do not buy bulk regulators. . Most bulk voltage regulators are produced by unqualified manufacturing companies, and the quality of the products produced by these companies generally cannot be guaranteed.
3. Due to the requirements of its performance and safety performance, the size and weight of the gas pressure regulator cannot be reduced indefinitely. When purchasing, do not buy one that is too small or light in weight for cheap. Products, small-sized pressure regulators do not have enough cavity buffering and pressure regulation, so the outlet pressure and closing pressure are difficult to meet the standard requirements. The sealing strength of a light-weight pressure regulator cannot be guaranteed, and leakage accidents are prone to occur.
