About the three way ball valve installation limit switch

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

To make a bracket utilize that handle.

Install the switch at the position where the limit is required, adjust the contact distance, and then string the normally closed contacts of the switch in the control loop, that is, the installation is completed.

There is no difference between the travel limit switch and other switches on the wiring, but when wiring, it is necessary to look at the control schematic diagram of the equipment to be controlled and wired according to the requirements of the figure, and the 220V control voltage is generally used in the three-phase electrical equipment, and there is also a safety voltage for control.

The contact capacity of the limit switch is small, generally less than 5A, and if the load capacity is small, it can be applied as the main control device.

It depends on what valve ball valve and butterfly valve are generally good to install, and others are a little difficult.

1. The limit switch is also known as the travel switch, and the function of the limit switch is to convert the mechanical displacement into an electrical signal, so that the operating state of the motor can be changed, so as to control the mechanical action or be used as a program control.

Limit switches can be installed on relatively stationary objects (such as fixed frames, door frames, etc., referred to as still life) or moving objects (such as cars, doors, etc., referred to as animals). When an animal approaches a still life, the connecting rod of the switch drives the contact of the switch, causing the closed contact to break or the disconnected contact to close. The circuit and motor are controlled by the change of the opening and closing state of the switch contact.

2. Wiring method:

The limit switch is connected in series to the contactor starting circuit.

NC stands for normally closed, NO stands for normally open, and C stands for the public end. 7 No. 8 terminal is connected to the power supply, which mainly provides power for the limit switch. Generally, there are 2 sets of switches for limit switches.

1 2 3 is normally open switch, 4 5 6 terminals are normally closed switch, according to the user's own needs to choose normally open or normally closed.

As the name suggests, the limit switch is to limit the position, similar to the car brake, the general lathe, the press have the limit switch, after reaching a certain effective distance, limit the workpiece to continue to move forward, play a protective role.

You're talking about what kind of limit switches. Position switches, magnetic switches...

What do you want to turn to? Installation? Or connect to a PLC?

Limit switch can be widely used in construction, port, mining and other industries of lifting, transmission machinery space coordinate control and limit, limit switch by high-precision large transmission ratio reducer and its output shaft synchronous mechanical memory control mechanism, sensor, because of the WTAU series limit switch has the characteristics of small size, many functions, high precision, adjustable limit, strong versatility and easy maintenance, installation and use of adjustment and other characteristics in construction machinery is extremely widely used.

The limit switch is a mechanical style, which needs to be contacted, and the proximity switch is a non-contact style, in order to make it use for a long time, the proximity switch is better.

Limit SwitchesThe AZ8 series of limit switches (travel switches) is a low-cost detection element suitable for many narrow installation environments. The switches are rugged and available in a variety of actuator options to suit a wide range of applications. Removing the housing, the front and sides of the contact block inside are fully exposed, which is very advantageous for installing the wiring, and the soft cable sheath on the bottom of the switch makes it easier to install the wiring.

This series is mechanical, limit switches, contact type, reliable and safe operation.

Proximity switch proximity switch, also known as non-contact travel switch, in addition to completing stroke control and limit protection, is also a non-contact detection device, used to detect the size of parts and speed measurement, etc., can also be used for frequency conversion counter, frequency conversion pulse generator, liquid level control and automatic connection of processing procedures. It is characterized by reliable work, long life, low power consumption, high complex positioning accuracy, high operating frequency and adaptation to harsh working environment.

Switch installation: Both types of switch installation are available. But it has to be done with minor adjustments. Because no matter what kind of valve stem there is, there is a stop position that must be adjusted to the appropriate position.

Switch selection: If you want to choose, it is better to choose a proximity induction switch. The accuracy of the control is good, that is, the line installation is more complicated.
