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...

The Fisher Fisher controller is primarily a system that uses digital codes representing processing parameters, processing sequences, and processing methods as control commands. Its processing efficiency and machining accuracy are both It is used in many places where small batches are produced, and it is also very popular. Then the editor is a big ...

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 ...

What is the difference between a valve limit switch and a valve positioner? Many novices don't know much about the product, and today I think I will answer the difference between the valve limit switch and the valve positioner! 1. The valve limit switch is also called a return signal, which is actually a display (reaction) valve switch ...

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 ...

United States Fisher Pneumatic Valve Positioner is the primary accessory to the Pneumatic Control Valve, which is a single-output valve positioner. It describes the main features and common faults of the valve positioner, as well as the treatment methods and protection methods. 1. The main features of the locator (1) Large-diameter pilot ...

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 ...

We often see such a scene on the steam pipeline, the pipe section that can be "straight" suddenly bent a section, I believe that many people who have seen it will have such doubts like me, this is not "painting snakes", in fact, the design of the pipeline operation has its own original...

Gate valves usually have single ram, double ram, wedge, parallel and other structural designs, among which wedge double ram (Z42, Z62 series) and wedge elastic ram (Z40, Z60 series) are widely used, the former when the gate is closed, the gate automatically fits the valve seats on both sides, and automatically compensates the processing position of the wedge angle.

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. Compressed filler (1) Plant fiber filler Made of hemp or cotton impregnated with oil, wax or other impermeable materials for use on low-pressure valves below 100°C. It is suitable for water, ammonia and other media. (2) Asbestos fiber filler Asbestos fibers have good heat resistance, can resist weak acids, strong alkalis, ...

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 ...

Fisher's broad range of sensing technology products provide customers with cost-effective process monitoring and inspection as well as process optimization Pervasive Sensing technology helps improve operational visibility to address safety, reliability, production, energy management, and environmental compliance. ...

When the Fisher controller is in use, we need to understand the classification of the controller and the control method of the controller. Through an in-depth understanding of the controller, we will be more proficient and convenient in use. Then the editor below will introduce these two aspects for us. Fisher Controller's ...

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 ...

Solenoid valves are selected for different media 1. Corrosive medium: it is advisable to choose plastic king solenoid valve, all stainless steel solenoid valve; For the strong corrosive medium must be selected isolation diaphragm type, such as: neutral medium, it is also advisable to choose copper alloy as the solenoid valve housing material, otherwise, there are often rust chips falling off in the valve housing.

Cavitation: When the static pressure of the liquid entering the first-class impeller in the pump is lower than or equal to the saturated vapor pressure at this temperature, the liquid vaporizes and produces bubbles. This vaporization and condensation produce ...

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 ...
