What are the common faults of valve actuators

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.

The common problems in the use of electric valves are: improper selection of parameters of the electric device, resulting in too large or too small output torque, causing the damage of the weak structure or the burning of the motor of the electric device; The technical communication between the electric power design institute, the complete set of units and the manufacturer is insufficient, which makes the design of the electronic control system of the electric valve of the design institute inconsistent with the actual electronic control system of the product.

The electric valve has two components, the electric actuation and the valve. The electric valve is mainly used to perform electric and as the main power, and the valve can be opened and closed by using this equipment, which can effectively realize the rapid opening and closing of the valve, and can successfully complete the purpose of the medium switch in the pipeline. The solenoid valve uses a solenoid coil magnetic field to pull the spool, so it can change the on-off of the valve body and the power-off of the coil.

What is an Electric Valve?

The electric valve is a kind of valve that is controlled by an electric actuator, and this equipment mainly uses an electric actuator to open and close the valve. The electric valve can be divided into two parts, one part is the upper part, which is generally composed of electric actuators, and the lower part of it is the valve, which is the same as ordinary valves, but uses an electric device. The advantage of this valve is that it can better control the liquid medium, and will not be affected by the climate and air compressor pressure.

However, the cost of electric valves is relatively high, and they cannot work in a humid environment for a long time, which will affect the electric actuator.

What is the main purpose?

Electric valves are generally used in the pipes of gas, liquid and wind systems, and are medium flow regulators, which can play a controlling role in AO.

Electric valve operation method

Before operating the electric valve, you should carefully read the operation manual, and you should not use it casually. Before operation, it is necessary to be clear about the gas flow direction of the electric valve to be installed, check the appearance of the electric valve to see if it is damp and damaged, dry it when it is damp, and repair it if there is a problem. Before starting the electric valve that has been out of service for 3 months, it is best to check the clutch to see if it can still operate and use properly.

What is an Electric Valve Controller?

The electric valve controller is a product used with a valve electric device to control the opening and closing of the electric valve. It is mainly divided into two types, one is a single-phase valve controller, and the other is a three-phase valve controller.

1. Single-phase valve controller.

Single-phase valve controller is used to control the rotary valve electric device of the instrument, can be switched by the external power supply to achieve on, off and intermediate position control, the product is widely used in chemical industry, civil building air conditioning system, fire protection system and water supply and drainage system.

2. Three-phase valve controller.

The three-phase valve controller is an instrument used to control the three-phase electric device of the valve, which can send instructions to the three-phase valve electric device to open and close, realize the remote control of the valve, and can also be manually operated on the spot. The products are widely used in power stations, petroleum engineering, water supply and drainage, food, light textiles, papermaking, medicine, water conservancy engineering, shipbuilding, municipal engineering, steel, coal and other units.
