Applications and prospects of Fisher DVC6200 valve positioner in the chemical industry

1. Selection of gate valves In general, gate valves should be preferred. In addition to steam, oil and other media, gate valves are also suitable for media containing granular solids and high viscosity, and are suitable for venting and low vacuum system valves. For media with solid particles, the gate valve body should be equipped with ...

In recent years, with the development of mechatronics, electric valves, an important mechanical product, have ushered in the world's leading market. Compared with traditional valves (manual valves, pneumatic valves), electric valves are more resource-saving, safe and reliable in operation. In today's increasingly loud call for environmental protection and safety, electric ...

The vibration of the control valve is generally divided into two states, one is the overall vibration of the control valve, that is, the entire control valve frequently vibrates on the pipeline or base. The other is the vibration of the spool of the regulating valve, which can be seen from the frequent movement of the valve stem up and down, and the following are the causes of these two vibrations and their treatment Measure...

The gas pressure reducing valve is to control the opening of the opening and closing parts in the 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 cooling water is sprayed in the valve body or behind the valve to reduce the pressure of the medium.

The power of Fisher is huge, the power of example is infinite, in today's market to achieve a better survival of our goods, we must have the characteristics of our own products, from the development of our valve industry, in the current market, such equipment ...

Fisher control valves are divided into electric control valves, pneumatic control valves and manual control valves, and the following mainly introduces pneumatic control valves and electric control valves.

Sensor - A device or device that can sense a measured pattern and convert it into a usable output signal according to the rule. It is generally composed of sensitive elements and conversion elements. A simple sensor is composed of a component (which also serves as a conversion element), which directly outputs electricity when it senses the measurement, such as thermoelectric ...

Routine maintenance is a planned overhaul before a control valve fails, which can be understood as preventive maintenance and usually includes the following tasks. 1. Stress relief Pipelines can produce various stresses due to improper combination or installation, such as thermal stress caused by high-temperature media, uneven tightening force during installation, etc.
