Within the range of the given spring pressure level, the outlet pressure can be continuously adjusted between the maximum value and the minimum value without jamming and abnormal vibration;

Do you know what the selection criteria of Low price pressure reducing valve products are? Let's take a look at it briefly!
1. Within the range of the given spring pressure level, the outlet pressure can be adjusted continuously between the maximum value and the minimum value without jamming and abnormal vibration;
2. For the soft-seal Low price pressure reducing valve products, there should be no leakage within the specified time; for the metal-seal Low price pressure reducing valve products, the leakage should not exceed 0.5% of the maximum flow;
3. When the outlet flow changes, the outlet pressure deviation value of the direct acting type is not more than 20%, and the pilot type is not more than 10%;
4. When the inlet pressure changes, the outlet pressure deviation of the direct acting type is not more than 10%, and the pilot type is not more than 5%;
5. Generally, the post-valve pressure of Low price pressure reducing valve products should be less than 0.5 times the pre-valve pressure;


6. Low price pressure reducing valve products have a wide range of applications. They can be used in equipment and pipelines for steam, compressed air, industrial gas, water, oil and many other liquid media. The medium flows through Low price pressure reducing valve products. The quantity at the outlet is generally expressed by mass flow or volume flow;
7. Bellows direct-acting Low price pressure reducing valve products are suitable for low pressure, medium and small diameter steam media;
8. Thin film direct acting Low price pressure reducing valve products are suitable for medium and low pressure, medium and small diameter air and water media;
9. Pilot piston type Low price pressure reducing valve products, suitable for various pressure, various diameters, various temperatures of steam, air and water media. If made of stainless acid-resistant steel, it can be applied to various corrosive media;
10. Pilot bellows type Low price pressure reducing valve products, suitable for low pressure, medium and small diameter steam, air and other media;
