Which valve electric head brand is better, and what are the brands and brands of imported electric v

Here are some 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, Chaoda, 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.

Domestic Changzhou Power Station auxiliary, domestic Rotok, Tianjin Baili Ertong, Tianjin North and other first-line brands; International brands include British Rotork, Omar AUMA, German SIPOS and so on.

Shanghai's Huquan valve, Tianjin's tee, Yangzhou's Bell, Wenzhou's Humoss, Shandong's Apocalypse are very good.

Electric valves are usually connected by electric actuators and valves, and become electric valves after installation and commissioning. The electric valve uses electric energy as the power to connect the electric actuator to drive the valve, and realize the opening and closing and adjusting of the valve. So as to achieve the purpose of switching or adjusting the pipeline medium.

The drive of the electric valve is generally driven by a motor, and it takes a certain amount of time to complete the opening or closing action, which can be adjusted. Relatively resistant to voltage shocks. The solenoid valve is quick to open and close quickly, and is generally used in places with small flow and low pressure and large switching frequency; Electric valves are reversed.

The opening of the electric valve can be controlled, and the state is open, closed, half-open and half-closed, which can control the flow of the medium in the pipeline and the solenoid valve cannot meet this requirement.

The three-wire electric valve has three lines, F and N, F stands for forward action (or open action) control line, R stands for reverse action (or close action) control line, and N stands for ground line. Solenoid valves are a type of electric valves; It is to use the magnetic field generated by the electromagnetic coil to pull the valve core, thereby changing the on-off of the valve body, the coil is powered off, and the valve core is returned by the pressure of the spring.

Let's take a look at what kind of valve the imported electric valve is, which refers to the control system composed of electric actuators and valves, which can be divided into two parts, the upper part is the electric actuator, and the lower part is the valve. Electric actuators can be divided into three categories, which are used for different valve categories: 1. Quarter turn:

0 90° quarter-turn for control of quarter-turn valves such as ball valves, plug valves, butterfly valves and louver valves; 2. Multi-turn type: it needs to run more than 360° to realize the opening and closing of the valve, which is mainly used for globe valves, pipe pinch valves and diaphragm valves; 3. Linear stroke: the output is the force, and the displacement is generated, which is mainly used for gate valves and slide valves.

Referring to the 15th International Industrial Brand Selection, the United States Weidun VTON, Germany Siemens, Japan Kitazawa Kitz have won word of mouth praise

There are many imported brands, recommend a few cost-effective bars, Taiwan Shanye, specializing in electric actuators, control valves, if you want to buy electric butterfly valves or electric ball valves, recommend them. The explosion-proof version of the Korean i-tork is more outstanding, and there is also a Japanese koso, if you can accept to buy Japanese products. Siemens is also good.

1. Reliable performance. PK-EP is used for the discharge device material. Compared to all known synthetic materials, PK-EP

There is the best performance and the highest reliability. PK-EP can withstand high temperatures (more than exhaust valves. The operating temperature is much higher). The O-ring uses the optimized material EPDM to ensure that the O-ring still works well at high temperatures.

resilience and operational reliability. The internal spring of the spool of the exhaust valve is made of special material and nickel-plated stainless steel to prevent oxidation (if oxidation affects the movement of the spool); The exhaust mechanism of the exhaust valve is very reliable and works well at the factory.

Each valve has passed the exhaust test and the pressure seal test. The individual components are cast with high precision, resulting in a perfect assembly.

2. Easy maintenance. The automatic vent is fitted with an H18 blocking valve, which allows the exhaust valve to be easily removed from the system for maintenance without the water flowing out of the system, so there is no need to drain the system.

3. Only exhaust, no drainage. The design of the steam and water separation disc adopts a special structure to ensure that there is no drainage during exhaust.

4. As long as the system is under pressure, the Shanghai Guardian valve is good, and the exhaust valve will be continuously exhausted.

Self-produced, joint venture brands are: German Benigo, Swiss Borimo, Danfoss.

OEM, joint venture brands are: Owen Top, Johnson, Honeywell.

Under the recommendation of a friend, the valve of Shanghai Huquan electric valve manufacturer is good, you can go to find out.

Electric valves usually consist of electric actuators and valves. The electric valve uses electrical energy as the power to drive the valve through the electric actuator to realize the opening and closing action of the valve. So as to achieve the purpose of switching the pipeline medium.
