Overview of High Sensitivity Steam Pressure Reducing Valves

The high-sensitivity steam pressure reducing valve is an essential accessory of the pneumatic control valve, which is mainly used to reduce the pressure of the air source and stabilize it to a fixed value, so that the control valve can obtain stable air source power for regulation and control.

According to the structural form, it can be divided into diaphragm type, spring film type, piston type, lever type and bellows type; According to the number of seats, it can be man-made single-seat and double-seater; According to the position of the disc, it can be divided into positive and negative type.

The operation of the high-sensitivity steam pressure reducing valve is controlled by the pressure behind the valve. When the pressure sensor detects that the valve pressure indication is rising, the valve opening of the pressure reducing valve decreases; When the pressure reducing valve is detected, the pressure decreases and the valve opening of the pressure reducing valve increases to meet the control requirements.

High Sensitivity Steam Pressure Reducing Valve – The pressure reduction ratio of this valve must be higher than the system value to a certain extent; It should be able to respond to positive or negative control signals even at maximum or minimum flow rates. These valves should be selected for the useful control range, i.e. 20% to 80% of the maximum flow rate. Normal is isometric or has isometric characteristics.

These types of valves inherently have the optimal flow characteristics and flow range required for proportional control.

There are many types of pressure reducing valves, the common ones are: pilot piston pressure reducing valves, membrane pressure reducing valves, bellows pressure reducing valves, proportional pressure reducing valves, self-operated pressure reducing valves, direct-acting piston pressure reducing valves, back pressure regulating valves, etc. They are suitable for different working media.

Different forms have different specific working principles. But the general principle is that the pressure reducing valve reduces the inlet pressure to a certain required outlet pressure through the throttling of the opening and closing parts, and keeps the outlet pressure stable. However, the general pressure reducing valve requires that the inlet and outlet pressure difference must be.

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following are the top ten domestic first-line valve brand manufacturers in 2022-2023, but for reference only: Suzhou Neway Valve Co., Ltd., Shanghai Guanlong Valve Machinery, Shanghai Qizhong Valve Manufacturing, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

The high-sensitivity steam pressure reducing valve uses the opening of the opening and closing parts in the control valve body to adjust the flow of the medium, reduce the pressure of the medium, and at the same time adjust the opening of the opening and closing parts with the help of the pressure behind the valve, so that the pressure behind the valve is kept within a certain range, and the outlet pressure is kept within the set range under the condition of changing the inlet pressure, so as to protect the living and production appliances behind.

1.For ease of operation and maintenance, the valve is generally installed upright on a horizontal pipeline.

2.The pressure reducing valve must be installed in strict accordance with the direction of the arrow on the valve body and the direction of fluid flow. If the water quality is not clean and contains some impurities, it must be in the pressure reducing valve.

Install a filter at the upstream inlet (we recommend a filtration accuracy of not less than.)

3.In order to prevent overpressure behind the valve, a pressure reducing valve should be installed not less than 4m away from the valve outlet.

4.The pressure reducing valve plays a certain role in the pipeline, in order to prevent the harm of water hammer, a small expansion tank can also be installed to prevent damage to the pipeline and valve, the filter must be installed in front of the inlet pipe of the pressure reducing valve, and the expansion tank must be installed behind the outlet pipe of the pressure reducing valve!

5.If you need to install a pressure reducing valve in a hot water system, you must install a check valve between the pressure reducing valve and the expansion tank. This not only allows the expansion tank to absorb the increased volume of water due to thermal expansion, but also prevents the influence of hot water backflow or pressure fluctuations on the pressure reducing valve, ensuring that the pressure reducing valve works normally for a long time.
