Emerson's new gas detectors protect employees and property by warning of hazards in extreme environments

In the use of Fisher Valve Positioner Control Valve, we may encounter some different situations, such as: positioner signal conditioner force instability, pneumatic valve source regulator force instability, positioner without pneumatic valve, etc., the following editors will introduce these situations. Fisher Fisher ...

The sealing surface is the key working surface of the valve, the quality of the sealing surface directly affects the service life of the valve, and the material of the sealing surface is an important factor to ensure the quality of the sealing surface. Therefore, the following factors should be considered when selecting the valve sealing face material: (1) Corrosion resistance. "Corrosive" ...

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 ...

1. Testing and adjustment 1. Whether it is manual, pneumatic, hydraulic or electric, all parts of this product have been seriously debugged before leaving the factory, and the user should uniformly fix both ends of the import and export when re-checking the sealing function Fixed, close the disc valve, apply pressure to the inlet side, and check whether there is any leakage on the outlet side, ...

FIELDVUE Fisher DVC6200 Series Valve Positioners are FISHER's next-generation high-performance valve controllers designed to respond to market needs and replace the DVC6000 Series DVC2000.

1. Medium (medium state, medium density, medium viscosity)? 2. Pressure range (design pressure?) Pre-valve pressure? After-valve pressure? Large differential pressure? Critical pressure? Saturated vapor pressure? ） 3. Flow rate (*** small?) Normal? Big? ） 4. Temperature? 5. Actuator ...

Ball valves are generally limited by sealing materials, because ball valves are usually formed by some plastic materials, the main principle of ball valves is to rely on metal balls to adjust the gas and liquid under the action of the medium, mainly the extrusion between the metal ball and the plastic valve seat to achieve the effect of adjustment. Between the seats ...

Butterfly valve is used in industry, its characteristics can withstand high temperature, the applicable pressure range is also high, the valve nominal diameter is large, the valve body is made of carbon steel, and the sealing ring of the valve plate is made of metal ring instead of rubber ring. The butterfly valve is a circular butterfly plate as the opening and closing part and rotates with the valve stem to open, close and adjust the fluid.

The opening and closing parts of the butterfly valve are butterfly plates, which are driven by the valve stem and rotate 90° around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjusting. It is mainly used to cut off the medium in the pipeline, with simple structure, flexible operation, fast switching, small size, short structure.

Emerson has introduced the Fisher L2e Level Controller, which provides comprehensive electric level control for a wide range of applications in production and process systems. The new Emerson Fisher L2e controller uses a force-balanced displacement sensor to detect the level of a single liquid or two...

Emerson's Asset Monitor edge analytics appliance improves visibility into critical assets and adds predictive analytics. Emerson introduces the AMS Asset Monitor Edge Analytics Appliance to digitally transform data and analytics for critical assets to improve operational performance and decision-making. AMS ...

In the past operation of natural gas pressure regulating system, terminal equipment such as pressure regulating cabinets, pressure regulating boxes, and pipelines in the distribution network have always been a relatively weak part of the monitoring means. As a result, problems such as non-troubleshooting and emergency gas shutdown accidents also make consumers and operators feel painful. Meanwhile...

When the pressure gauge is connected to the pipeline, a bend should be added between the pressure gauge and the pipe connection. Why is that? What does this do? Let's take a look! This thing that connects the pressure gauge and the pipe is the pressure gauge bend (also referred to as the gauge bend), which is officially called the buffer pipe. ...
