On the issue of not having SIS on the production plant or storage tank farm, share your opinions: First of all, we have to figure out what SIS is for, in fact, SIS is not as mysterious as imagined, its function is the same as safety valves, rupture discs, etc., is a safe protective layer. That...

Use and Maintenance: 1. It is recommended that the user unit appoint a special person to be responsible for the use and maintenance 2. Regular maintenance 1-2 times a year is the best way for the solenoid valve to work reliably and live long. The following 4 conditions inside the solenoid valve are the reasons that hinder the normal operation of the solenoid valve and shorten the life of the solenoid valve. ⑴ ...

How Fisher Pneumatic Control Valves Work: Pneumatic control valve is usually composed of pneumatic actuator and control valve connection, installation and commissioning, pneumatic actuator can be divided into single-acting and double-acting two-acting, single-acting actuator has a return spring, and double-acting actuator has no return spring. ...

1. Pre-treatment of pickling passivation If there is surface dirt before pickling and passivating the stainless steel workpiece, it should be cleaned mechanically, and then degreased and degreased. If the pickling solution and passivation solution can not remove the grease, the presence of grease on the surface will affect the quality of pickling passivation.

Emerson's TopWorxTM PD series uses Hall effect technology to reliably detect and control valve position. Emerson's TopWorxTM PD series is designed for demanding applications. Hall effect technology is used to reliably detect and control valve position. High resolution imag ...

FISHER Valve Positioner From mechanical to intelligent, FISHER Intelligent Valve Positioner can effectively reduce the labor intensity of maintenance personnel in the first line. Intelligent communication mode: The obvious feature of intelligent valve positioner is intelligent communication. For our process industry ...

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 ...

1. The pipeline of the pipeline centrifugal pump is matched Some users of pipeline centrifugal pumps think that this can improve the actual head, but in fact, the actual head of the pump = total head - loss head. When the pump model is determined, the total head is fixed; The loss head is mainly due to the resistance of the pipeline, and the smaller the pipe diameter ...

There are many different types of Fisher Fisher controllers, and today I will share with you some small knowledge of Fisher valve controllers. Fisher Fisher Valve Controller Classification: Pneumatically operated valves are operated by means of a positioner to receive an input signal from the process controller.

There are intelligent positioners and mechanical positioners for valve positioners, and today we are talking about the latter mechanical positioner, which is the same as the positioner shown in the picture Schematic diagram of valve positioner structure In the figure, the components of the mechanical pneumatic valve positioner are basically explained one by one, and the next thing is to look at it.

This article today gives you a detailed introduction to the basic information of the United States Fisher control valve nameplate, the information on the Fisher nameplate, you can click on the attachment to view. location + number 865 represents Tianjin Fisher factory production, 382 represents Malaysia factory production, and of course ...

The Fisher Series 299H Regulator is a pilot regulator with VSX2 type, which provides customers with controllable regulation of pressure and flow, mainly used in branch and commercial portals of industrial conveying and LNG regulator skids. The product has been verified and improved by the market for a long time, and has been fully tested to f...

Rules of thumb for flow characterization selection Different applications favor different valve flow characteristics. These rules of thumb do not cover all situations, but they can address many of the typical situations encountered in the process industry. Linear control valves are often chosen for pressure control, including near-constant ...

Fisher Fisher Valve Positioner Type, according to the structure, is divided into Fisher 3660/3661/3710/Pneumatic Valve Positioner, FISHER3528I Electric-Pneumatic Valve Positioner and Fisher DVC6200/DVC2000 Digital Intelligent Valve Positioner, which has single acting and double acting, and is the main attachment of the control valve.

1. Definition of dead zone In the field of instrumentation, it is also known as the insensitive area of the instrument. A finite interval in which a change in the input does not cause any perceptible change in the output of the instrument. The dead zone is mainly caused by friction and intermittent intermittent between the internal components of the instrument. In the field of valves, valves are dead ...

The filter, pressure reducing valve and lubricator together form a pneumatic triplet. The filter is mainly responsible for filtering liquid water, oil and impurities in the compressed air, the pressure reducing valve is mainly responsible for controlling the system pressure, and the lubricator is responsible for the oil lubrication of the back-end components. In general, the lubricator is not used much, because ...

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 ...

When choosing a valve stem packing, it should be determined according to the specific conditions. The method we generally choose is: between pressure and temperature, only one *** value can be satisfied; When choosing a high-temperature valve packing, the temperature should be considered first; For corrosive media with low temperature and pressure, the ...
