The Difference Between Pressure Reducing Valve And Pressure Reducer

Pressure Reducing Valve is to control the opening of the opening and closing parts of the valve body to regulate the flow of the media, to reduce the pressure of the media, and to adjust the opening of the opening and closing parts by means of the pressure behind the valve, so that the pressure behind the valve remains within a certain range, keep the outlet pressure within a set range to protect the pipes and valves that follow in the event of changing inlet pressure.

The function of the pressure reducing valve is to control the fixed outlet pressure of the main valve. The outlet pressure of the main valve does not change with the change of the inlet pressure and the outlet pressure of the main valve does not change with the change of the outlet flow. The pressure reducing valve is a throttling element whose local resistance can be changed, that is to say, by changing the throttling area, the velocity and the kinetic energy of the fluid can be changed, resulting in different pressure loss, thus the aim of pressure reducing can be achieved. Then rely on the control and regulation back system, so that the pressure fluctuations after the valve and spring force balance, so that the pressure after the valve in a certain error range should be kept constant.

A pressure reducer is used to reduce the high pressure gas stored in the cylinder to low pressure gas because the pressure in the cylinder is higher but the pressure in the Oxy-fuel welding and cutting and the use point is lower, and shall ensure that the required working pressure from beginning to end to maintain a stable state. In short, the regulator is to reduce the high-pressure gas to low-pressure gas, and to maintain the output gas pressure and flow stability unchanged. Decompressor can be divided into oxygen decompressor and acetylene decompressor according to different uses, can also be divided into centralized and post-type two categories.

Although they are called the same, the effect is the same decompression, but their application is not the same.

So before purchasing, please be clear about your requirements, and explain your requirements to us, we will recommend the most suitable pressure relief valve according to your requirements.
