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 influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, 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.

This is not the case with the model on our side.

1. Mechanical steam trap:
The mechanical type, also known as the float type, uses the density difference between the condensate and the steam to make the float lift and drive the valve disc to open or close through the change of the condensate liquid level, so as to achieve the purpose of steam resistance and drainage.
2. Thermostatic traps:
This type of trap uses the temperature difference between steam and condensate to cause the deformation or expansion of the temperature sensing element to drive the valve core to open and close the valve.
3. Thermodynamic traps.
According to the principle of phase change, this type of trap relies on the different thermodynamic principles of flow velocity and volume changes when steam and condensate pass through, so that different pressure differences between the upper and lower parts of the valve plate are generated, and the valve plate is driven to open and close the valve.

Steam traps can be divided into three types according to their different principles of action:
1. Mechanical traps: free float® traps, free semi-float® traps, lever float traps, and inverted bucket traps.
2. Thermostatic traps: diaphragm traps, bellows traps, and bimetal disc traps.
3. Thermodynamic traps: thermodynamic (disc traps), pulse traps, and orifice traps.
Wenzhou Niwei Valve has many years of experience in valve making, and is a high-tech innovative valve production enterprise integrating design, development, manufacturing, testing, sales and service. The technical quality and manufacturing process of the company's steam trap products have reached the level of similar products. Due to the high accuracy of the float, the sealing performance of the trap can be ensured, and the entire spherical surface can be sealed, which has a long service life and is easy to use.

Commonly used trap models are:
1. Thermostatic type: including bimetal sheet type, bellows type, membrane type, and liquid expansion type.
2. Thermodynamic type: including disc type, pulse type, labyrinth type, orifice type.
3. Mechanical type: including bell-shaped float type (inverted bucket type), float type, bell-shaped float type is divided into lever inverted bucket type, differential pressure inverted bucket type, semi-float type and positive floating bucket type.
The float type is divided into free float type, lever float type, three-point support float type, and pilot float type.
4. Pump traps: including inverted bucket type and lever float type.
The type of trap varies from manufacturer to manufacturer, and the problem should be in the form of a trap.

This is an adjustable bimetal disc trap, model TB6F, TB11F, which is a thermostatic type suitable for heat tracing systems.

Yongjia Yijie Valve Factory is a professional manufacturer of steam traps, we have gone through a variety of tests before leaving the factory, **0577-57999577

Free Float® traps, '-i' indicates a float diameter of 50mm, which is equivalent to the JH3F of TLV.
Since the provisions of JB T308 cannot meet the characteristics of this trap, the manufacturer can only add the code to show the difference. For example, TLV's JH3F, JH5F, JH7F, F, are 6 specifications of traps with different ball diameters, and the displacement is kg H, but according to the provisions of JB T308, their models are CS41H-16C, which is obviously unreasonable and cannot truly represent the characteristics of the product. Adding an endnote number is necessary.

You may have this as a matter of which factory made it yourself, and it may be the size of the float inside.

It's easy to use, it's imported. But it is recommended that you support domestic production and do not use imported ones.

In fact, the technology in China is almost the same as that in foreign countries, and the most important thing is that the Spirax Sarco traps you buy are basically copycat products, not imported from the UK. It should be noted that the traps used in our factory are all designated Shanghai Mingao traps, and the old state-owned factories are in the wild, and the quality and after-sales service are more guaranteed. Hope it helps.

It should be good, and the trap should be used on the right steam equipment to reflect its function.

Our company is doing engineering projects, in the trap and steam valves this piece of the pursuit of cost-effective products, long-term cooperation of a few, I think the valve of Shanghai pants casting Zhuo is not bad, the quality is OK, but also affordable to take a friend Jane, pre-sales and after-sales are very powerful,
1.Operating Differential Pressure: Operating Differential Pressure: The pressure difference between the inlet pressure and the outlet pressure (back pressure) of the trap. If the outlet end is atmospheric, the back pressure is zero; If the pressure fluctuates, the maximum pressure difference should be taken. >>>More
Inverted bucket traps and free float® traps are both mechanical traps. They work on the basis of the density difference between condensate and steam, have a relatively small degree of supercooling, and are suitable for hydrophobicity of heating equipment in production processes. >>>More
Venturi. A steam trap is a type of steam trap that appears to be a new type of steam trap. It seems to be new to say that the basic principle is still thermodynamic orifice plate type (which has long been obsolete) hydrophobic. >>>More
