To ensure safe and efficient use of gas cylinders in applications like welding and cutting, a pressure reducer is essential. These devices lower the high-pressure gas stored inside the cylinder to a stable, usable low-pressure level, maintaining consistent performance throughout operation. This makes them crucial for industrial and commercial applications where precision and reliability are required.

Product Details Introduction
1) This regulator is ideal for industrial manufacturing, construction, and installation projects.
2) The dual-gauge design allows users to easily monitor both the cylinder pressure and the working pressure, ensuring accurate control during use.
3) The main body is made from high-quality brass, while the upper cover is constructed from aluminum alloy with a spray finish. For the 60mm pressure gauge, an external relief valve is included, and sintered bronze filters are installed at the air inlet for enhanced performance and safety.
Different Types and Models of Regulators
1. The SJ7-1O pressure reducer features a brass body. Its two-stage pressure relief system includes components such as a valve jack, pressure regulating spring, elastic membrane device, and pressure relief door. The first stage reduces high-pressure gas to medium pressure (around 2 MPa), which is then further reduced by the second stage to a usable low-pressure level.
In the second stage, adjusting the pressure regulating screw controls the opening and closing of the pressure reducing valve via the pressure spring, elastic membrane assembly, and valve jack rod, allowing precise adjustment of the oxygen supply or complete shut-off.
2. The QD-1 type pressure reducer has an inlet joint thread size of 315.875mm, with an inner diameter of 5.5mm and an outlet inner diameter of 6mm. It can handle a flow rate of 80m³/h. It also includes high and low-pressure oxygen gauges, measuring pressures in the high-pressure chamber (inside the cylinder) and the low-pressure chamber (working pressure). The high-pressure gauge range is 0–25MPa, while the low-pressure gauge covers 0–4MPa.
When using the QD-1 model, turning the adjusting screw clockwise opens the decompression valve, allowing high-pressure oxygen to flow into the low-pressure chamber, where it expands and lowers the pressure—effectively decompressing.
3. The SJ7-10 double-stage pressure reducer has an inlet joint nut thread size of G1/5.875mm, with a joint diameter of 7mm. The outlet joint diameter can be selected as 5mm or 9mm depending on application needs. The high-pressure gauge range is 0–25MPa, and the low-pressure gauge range is 0–4MPa.
