Norgren valve classification

Views:1     Author:Site Editor     Publish Time: 2021-03-12      Origin:Site

Norgren solenoid valve is used in many fields because of its control accuracy and flexibility. As a gatekeeper of circuit safety, the application of solenoid valve must be safe and reliable. In different control systems, the required Norgren valve models and functions are also different. Therefore, the appropriate product must be selected according to actual requirements.

 

Here is the content list:

  • What is the intention of the Norgren solenoid explosion-proof valve?

  • What is the difference between Norgren solenoid cryogenic valve and ordinary ones?

  • What working environment is Norgren solenoid anti-corrosion valve suitable for?

  • How to introduce Norgren solenoid proportional valves?

  • What is the working principle of Norgren solenoid pneumatic valve?

 

What is the intention of the Norgren solenoid explosion-proof valve?

Norgren solenoid explosion-proof valve is a special solenoid valve series product specially designed to transmit inflammable and explosive media or dedicated to explosive hazardous locations. To different environments and fluids, the operator should choose solenoid valves with different explosion-proof levels.

The coil shell of the Norgren solenoid explosion-proof valve not only has the explosion-proof effect of withstanding the gas explosion pressure, but also has a blocking effect on the energy transfer of the gas explosion, and the safety performance is higher.

 

What is the difference between Norgren solenoid cryogenic valve and ordinary ones?

All parts of Norgren solenoid cryogenic valve have undergone special low-temperature treatment to ensure the low-temperature performance, suitable for liquid nitrogen, liquid ammonia, liquid oxygen and ultra-low temperature refrigerants, etc. It is a common pipeline switch element in automatic control systems.

The assembly of Norgren solenoid cryogenic valve is also different from ordinary valves. The parts need to be strictly cleaned to remove any oil stains to prevent leakage due to deformation of the valve due to temperature changes when the valve is working at low temperatures.

 

What working environment is Norgren solenoid anti-corrosion valve suitable for?

Norgren solenoid anti-corrosion valve is suitable for a variety of strong acid and alkali gas and liquid working media, and is widely used in medical and pharmaceutical, chemical, environmental protection or cleaning equipment and other automated control systems.

In fact, the service life of the Norgren solenoid anti-corrosion valve under different operating conditions is completely different. Therefore, before purchasing Norgren solenoid anti-corrosion valve, full communication between the user and the manufacturer is essential.

 

How to introduce Norgren solenoid proportional valves?

Norgren solenoid proportional valves are a new type of hydraulic control device. On ordinary pressure valves, flow valves and directional valves, proportional solenoids are used to replace the original control parts.

According to the input electrical signal, Norgren solenoid proportional valves can continuously and proportionally control the pressure, flow or direction of the oil flow remotely. Norgren solenoid proportional valves have pressure compensation performance, output pressure and flow cannot be affected by load changes.

 

What is the working principle of Norgren solenoid pneumatic valve?

Norgren pneumatic valve belongs to domination part in the system. Norgren pneumatic valve is generally divided into two types, direct-acting and pilot-operated, and distinct kinds have various working principles.

  • Direct-acting type

The direct-acting Norgren solenoid pneumatic valve attracts an iron core by the suction force of the solenoid coil after it is energized. The up and down movement of this iron core will control the open or closed state of a small hole, and the open or closed state of the small hole can directly cause the air inlet and the air outlet are connected or isolated.

The direct-acting Norgren solenoid pneumatic valve is limited by the electromagnetic force, and the hole diameter cannot be made too large. Therefore, the flow of the direct-acting solenoid valve is generally small.

  • Pilot-operated type

The pilot-operated Norgren solenoid pneumatic valve realizes a 2-position or 3-position function by moving a sliding core in the valve body to achieve the required state of different working conditions.

 

A solenoid valve occupies very little cost in the entire automatic control system and even the production line, but if it is wrongly selected, the damage caused is huge. But don't worry, Shenzhen Juson Automation Company Limited. provides you compact solenoid valve with hot forging process. We also provide the classification method and applicable occasions of Norgren valve. You can consult our customer service for the most comprehensive explanation.
