What is Ammonia?

Ammonia is a colorless, pungent-smelling, poisonous gas. Ammonia is highly volatile, easy to diffuse in the air, and easy to explode when exposed to open flame or high temperature.

Ammonia is an important chemical raw material, widely used in chemical fertilizers, medicine, plastics, synthetic fibers, coatings, dyes and other industries. At the same time, ammonia is also used in refrigeration, freezing and air conditioning and other fields. Due to the toxicity and flammability of ammonia, it is necessary to pay attention to safety measures during use and transportation to avoid accidents.

Therefore, it is necessary to select a suitable valve to build an ammonia transport pipeline or an ammonia storage tank to avoid danger caused by leakage.

Applications of Ammonia

Agriculture

Used to make nitrogen fertilizer to provide nitrogen needed by plants and promote crop growth

Chemical Industry

It’s an important raw material for manufacturing chemicals and is necessary in many industrial processes

Refrigeration And Air Conditioning

It is a refrigerant widely used in refrigeration and air-conditioning systems with good cooling performance and heat conduction properties

Detergent

Used as a cleaning agent to remove dirt and grease, and to have bactericidal and disinfectant properties

Textile

Used as a dye for textiles and an alkaline agent in the printing process, it can help the dye penetrate the fiber and improve the dyeing effect

Why Valves Are Required For Ammonia Service

Flow Control
In the ammonia production process, valves can control the flow of gases, liquids or mixtures. Ensure that flow rates remain within the required range under specific process requirements
Pressure Control
During the production process, valves can be used to regulate the pressure of the system to ensure that the required pressure is maintained within a safe range
Directional Control
During the production process, valves can be used to change the flow direction of fluids to meet the requirements of different process steps

Advantages of Using Actuator Valves For Ammonia Service

Automatic Control To Ensure Personal Safety
Due to the corrosive nature of ammonia, using actuator valves allow for easy remote control and reduces the chance of human injury.
Increase Productivity
The biggest advantage of the actuator valve is that it can carry out targeted flow regulation and improve the production efficiency of the project according to the needs of the project, combined with the control system and transmission signals.
