Fisher Fisher-1098EGR and 1098H-EGR Decompression Regulators

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 ...

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. ...

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...

Fisher valve positioners use an I/P electrical converter that converts an electrical signal into a gas signal. So what do we need to pay attention to during the conversion process? How do I make the switch? Here's how it goes. The I/P electrical converter of the Fisher valve positioner is made from a gas source through a constant throttle ...

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.

Performance characteristics of electric control valves The electric control valve is composed of a combination of electric actuator and control valve, and its main features are: 1. Light weight and beautiful appearance. 2. Functionally, it can replace many products with incomplete functions, simplify the modeling, and solve the complex factory management, complex selection, ...

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 ...

What should I pay attention to when the automatic initialization of the valve positioner is unsuccessful? DVC6200 smart valve positioners need to be initialized before they are put into use, and due to incorrect installation and use, they often run into trouble during the initialization process. place There are several aspects that need to be noted: 1 ...
